No, currently it is not possible. Part 2: Testing and building projects If you omit it, there will be a validation error on an attempt to generate settings from this script. Currently, if Kotlin DSL uses context parameters then the settings of such projects cannot be edited via the TeamCity UI (see TW-63565 for details). } In this part of the series, we’ve looked at how to get started configuring the builds in TeamCity with Kotlin DSL. When a new commit is detected in a settings repository, TeamCity runs the DSL scripts found in this commit and applies the result to the settings on the TeamCity server or reports errors on the project's Versioned Settings tab. import jetbrains.buildServer.configs.kotlin.v2019_2.buildSteps.script asked Aug 6 at 11:46. Locate the task node: Plugins | teamcity-configs | teamcity-configs:generate, the Debug option is available in the context menu for the task: TeamCity allows editing a project settings via the web interface, even though the project settings are stored in Kotlin DSL. Problem: I changed the URL of the VCS root where settings are stored in Kotlin, and now TeamCity cannot find any settings in the repository at the new location. Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language). The build chain exists in repo RA. project { Kotlin provides first-class support for DSLs, which allows us to express domain-specific operations much more concisely than an equivalent piece of code in a general-purpose language. All changes to the one project will be replicated to another. For instance, instead of using TeamCity templates, one can create a function or class which will encapsulate project common settings. We will start with the basics on how to get started with configuration-as-code in TeamCity. There’s also a Kotlin DSL for Gradle available: Gradle-Script-Kotlin s1m0nw1 Simon is a software engineer based in Germany with 7 years of experience writing code for the JVM and also with JavaScript. } Contribute to fkorotkov/k8s-kotlin-dsl development by creating an account on GitHub. In the example above the id must be specified. You really should have mentioned very clearly at the start of the article (or at least at the start of Enable Versioned Settings) that TeamCity was going to automatically, and without prompting, try to commit to a branch. }, fun readScript(path: String): String { In general, TeamCity processes a DSL parameter as a string. This plugin bundles the Kotlin 1.x Standard Library for JDK 8, which can be used by other plugins as a dependency.It allows managing library updates independently from plugins. Each of these projects can have own values of context parameters, and the same DSL code can produce different settings based on values of these parameters. https://kotlinlang.org/docs/reference/mpp-dsl-reference.html Teamcity 10 – Configuration As Code With Kotlin DSL. } name = "Hello world" // build chain definition: In this series, we've been explaining how TeamCity can integrate with .NET and walking you through a tutorial. Since TeamCity 2019.2, you can customize the DSL generation behavior using context parameters configured in the TeamCity UI. Configuration as code is a well-established practice for CI servers. Non-default values of options for implicit snapshot dependencies can be set via the options lambda argument of any block. , project { In part two, we’ll dive a little deeper into the DSL, modify the script, and see some of the benefits that Kotlin and IntelliJ IDEA already start providing us with in terms of guidance via code assistants. The benefits of this approach include versioning support via VCS repository, a simplified audit of the configuration changes, and improved portability of the configurations. This is actually described in the next article: https://blog.jetbrains.com/teamcity/2019/03/configuration-as-code-part-2-working-with-kotlin-scripts/. scriptContent = "echo 'Hello world!'" 17 Mar 2017 | Jeffrey Palermo. We can also create custom DSL using, Infix. } } } A general-purpose language, such as Kotlin or Java, on the other hand, can be used in multiple parts of one application. The following example illustrates a typical pipeline for compiling and deploying an application: If you define a build chain in a pipeline style, ensure there are no explicit snapshot dependencies defined within the referenced build configurations themselves. The generated settings layout is a .teamcity directory with two files: settings.kts and pom.xml. It aims to provide Gradle users with a rich, flexible and statically-typed approach to developing build logic in conjunction with the best IDE and tooling experience possible. As a result, the new project will include one VCS root and a build configuration with a Maven build step and a VCS trigger. }) You can leverage all the functionalities of Kotlin in your Gradle file. Since TeamCity 2019.2.1, you can establish access to external libraries in private repositories. buildType(Deploy) This project has already been built on the demo TeamCity server. To define specific values for context parameters, add the block to your pom.xml file. ... In this tutorial, we'll see how powerful Kotlin language features can be used for building type-safe DSLs. Select Kotlin as the format. The result of scripts execution is configuration files, which are loaded by TeamCity server and then behavior of the newly triggered builds changes. import jetbrains.buildServer.configs.kotlin.v2019_2. You can refer to them by their relative paths. }), val dataFile = File(DslContext.baseDir, "data/setup.xml"), project { Click Ok and follow the wizard. If you are writing your source code in Kotlin then it is good to have your build scripts in Kotlin as well. buildType(BuildB) name = "My project" project { But there is also another way to define the same build configuration: In this case the usage of the id() function call is optional because TeamCity will generate the id based on the class name (HelloWorld in our case). To go back, click Edit in UI. You can refer to the configuration in the other project by the id, but you cannot obtain the instance. script { When creating the project from a repository URL, TeamCity will scan the sources. Or, fork the source repo and build the project yourself. There are more attributes that we can specify for the VCS root object, like branches specification, and authentication type if needed. This is the main difference of the non-portable DSL format from portable. Gradle’s Kotlin DSL provides an alternative syntax to the traditional Groovy DSL with an enhanced editing experience in supported IDEs, with superior content assist, refactoring, documentation, and more. The new DSL API version is usually introduced when there are significant incompatible changes in DSL API. script { } In addition to this, it is possible to define which settings to take when the build starts. The changes to the settings are then always reflected on the server. import jetbrains.buildServer.configs.kotlin.v2019_2. Make sure the Generate portable DSL scriptsoption is enabled. } }) Solution: Since TeamCity 2019.2, it is possible to access the location of the .teamcity directory from DSL scripts with help of the DslContext.baseDir property, for example: Since 2019.2, this is the preferable approach as TeamCity no longer guarantee that the current working directory for DSL scripts is the same as the .teamcity directory. As a result of this change, the build configuration will not contain the builds' history anymore. Defining this at the `Project.kt` level in our DSL, would give us a good oversight of what’s taking place. Click Apply, and TeamCity will commit the generated Kotlin files to your repository. But what about cases when a domain-specific language is the better fit for our task? } * When we use Kotlin DSL and make changes to the scripts in our favorite IDE, the “source of truth” is located in the VCS repository. The Maven Projects tool window is displayed. Check out the blog post series on using Kotlin DSL in TeamCity. You will be redirected to the Attach Build History tab. If you have a repository with .teamcity containing settings in portable format, you can easily create another project based on these settings. Our TeamCity configuration may not change often depending on the project, but when they do they could introduce a slew of headaches when “things don’t work no mo”. Could you describe your use case a little more in detail? } As stated earlier, DSLs (domain-specific languages) are "languages specialized to a particular application domain". }), params { I strongly believe Transition X style DSL reduces complexity and simplifies workflow when working with transitions. Creating our own Pipeline definition After the commit to the repository, you will get the .teamcity settings directory with the following files: settings.kts – the main file containing all the project configuration, pom.xml – required when opening the project in an IDE to get the auto-completion feature, and ability to compile code and write unit tests for it. This would be awesome. org.gradle.api.artifacts.ivy. Note: DSL scripts is essentially another way of writing TeamCity configuration files. }, object Build : BuildType({ All the code relevant to the TeamCity configuration can be stored in this file, but it can also be divided into several files to provide a better separation of concerns. Click the plus sign, select Import module and choose the folder containing your project settings. Fix the URL in the Kotlin DSL in the version control and push the fix. import jetbrains.buildServer.configs.kotlin.v2019_2.Project buildType(Compile) org.gradle.api.artifacts.component. The parent type of the object, GitVcsRoot, indicates that this is a git repository that we’re going to connect to. Creating NuGet packages As in, I can just copy and paste it over? ${teamcity.dsl.version} You can sign in as a guest and explore the build results. Such auxiliary scripts can be put in the .teamcity directory alongside the settings files. To do that, you need to override the validate() method. Open the folder in IntelliJ IDEA, you will see the following layout: Essentially, the .teamcity folder is a Maven module. Kotlin DSL. I was able to locate the configs-dsl-kotlin-10.0.0.jar file and it resolved some of my reference problems. buildType(BuildA) Since then some organisations like JetBrains have started to use GKD in production which makes it a great time to start using it, even in non production level projects. The Build object inherits from the BuildType class that represents the build configuration in TeamCity. If the uuid is changed, then the data is lost. Android screen design is not the only domain where XML and Java are valid options. This can be useful if you wish to build your app's navigation dynamically. The Kotlin DSL files producing build configurations and VCS roots are placed under the corresponding subdirectories. This chapter provides details of the main Kotlin DSL constructs and how to use it to interact with the Gradle API. Usually it takes a minute or two, depending on the Changes Checking Interval defined for the VCS root where the DSL is located. For instance, you can add a new build step, and hit the preview toggle without saving the changes – you will see the DSL snippet that you need to add to the build configuration. object HelloWorld: BuildType({ The Configuration as Code plugin can be used to manage the global system configuration of Jenkins. buildType(Compile) A is in repo RA and B is in repo RB in teamcity. Click Apply. These IDs usually look like: _. parallel (options = { onDependencyFailure = FailureAction.CANCEL }) { // non-default snapshot dependency options steps { val buildChain = sequential { Consider the following code:This is completely legitimate Kotlin code.You can play with this code online (modify it and run in the browser) here. TeamCity Kotlin DSL provides an alternative way to configure a build chain in a pipeline style. After making the necessary changes in settings.kts file, you can submit them to the repository – TeamCity will detect and apply them. Build steps and other configuration changes work as advertised, with the exception of the VCS root - changes in settings.kts to things like branchSpec do not reflect in the build. I want to be able to add dependencies and pass parameters to it. Kotlin Expertise Blog - In this article, I am taking a look at the Gradle Kotlin DSL as an alternative to the classic Groovy approach: It offeres much better support in IDEs as it is backed by a statically typed language instead of a dynamic one. buildType(Package) You can also perform validation locally by generating XML configuration files with help of generate task. scriptContent = "echo Build Successful" We will then dive into the practicalities of using Kotlin DSL for build configurations. In Kotlin, we can find examples of DSL implementations in several libraries, for example Anko. * To catch up with the demo, read the previous posts: DSL is also good in case when you need to have a big amount of similar build configurations. For our example, we'll create a simple tool for constructing SQL queries, just big enough to illustrate the concept. Before 2019.2, the following code could be used: To reorder subprojects or build configurations inside a project via DSL, similarly to the respective UI option, pass their lists to subProjectsOrder or buildTypesOrder respectively. It is best to add a Kotlin DSL configuration to an existing project in TeamCity. To make this instrument more useful and easier to understand, we have reworked the REST API documentation. Since these IDs must be unique, there cannot be two different entities in the system with the same ID. The other dependencies that we see in the list are the Kotlin DSL extensions contributed by TeamCity plugins. It has just two attributes: the name, and the URL of the repository. teamcity-configs-maven-plugin Make sure it specifies correct credentials; TeamCity won't be able to commit changes if anonymous authentication is used. buildType(Test1) Thanks for the feedback. Managing context parameters in UI You can manage project context parameters on the Versioned Settings | Context Parameters tab. We recommend keeping this ID constant, so the changes made in the DSL code are consistently applied to the respective build configuration in TeamCity. The buildType(...) function registers a build configuration. When versioned settings in Kotlin format are enabled, TeamCity commits the current settings to the specified settings repository. 2. Try customizing your watch face even further using DSL by reviewing all the options in the model/AnalogWatchFaceStyleModels.kt class. script { Select a required VCS root. Let's take a look! To open the Kotlin DSL project in IntelliJ IDEA, open the .teamcity/pom.xml file as a project. } swabra { For instance, you can find a project that defines settings you want to use in your Kotlin DSL project and use the Download... action to see what the DSL generated by TeamCity looks like. For our demo project, TeamCity will detect the presence of the Maven pom.xml and propose the required build steps. Note: right after the Kotlin DSL settings are enabled in your project, the web UI for this project will become read-only until the TeamCity server detects its own commit and applies it back to the project. In Kotlin, infix helps us to create custom DSL similar to like how we write in English. There are several domain-specific languages that we’re already familiar with, like … } To fix this problem, change the ID of the affected entity. Regardless of whether you are starting from scratch or you have an existing project. In the non-portable format each project has the following settings.kts file: This is the entry point for project settings generation. Using the version control-stored DSL enables you to define settings programmatically. Basically, it represents a Project instance which generates project settings. Summary. org.gradle.api.artifacts.dsl. ... id is the absolute ID of the project, the same ID you'll see in browser address bar if you navigate to this project, parentId is the absolute ID of a parent project where this project is attached. Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language).. Test /* a context parameter that defines a build configuration name; its default value is `Test Build` */ However, if you need to modify the build configuration ID in the DSL, note that for TeamCity this modification will look like if the configuration with the previous ID was deleted and a new configuration with the new ID was created. To group builds that will run in parallel to each other inside a chain, use the parallel method: the first subsequent build after the parallel block will depend on all the preceding parallel builds. password("pass-to-bucket", "credentialsJSON:12a3b456-c7de-890f-123g-4hi567890123") To get familiar with Kotlin API, see the online documentation on your local server, accessible via the link on the Versioned Settings project tab in the UI or by running the mvn -U dependency:sources command in the IDE. steps { Basically, a DSL is a language that focuses on just one particular part of an application. It has clear advantages over Groovy like having auto suggest support and writing custom Gradle tasks becomes easier as it is in the same language as your source code using kotlin dsl. My build exists in another project in teamcity and all I have is the extId for it. See details. The DSL comes in a series of packages with the main one being the actual DSL which is contained in the configs-dsl-kotlin-{version}.jar file. object BuildB: buildType ({ } In the project configuration, under Versioned Settings, select the Synchronization enabled option, select a VCS root for the settings, and choose Kotlin format. In Android, every tutorial teaching you the basics describe how to design screen through XML files. I need the result of B reported back in RA so that if B is not successful, the pull request in RA should fail. 3. kts is a Kotlin Script file, different from a Kotlin file (.kt) in that it can be run as a script. object BuildA: buildType ({ I’ll add a warning about it. We explored the main components of a TeamCity configuration script and its dependencies. See the documentation on the public TeamCity server as an example. /* some comment text */ To start working with Kotlin DSL in TeamCity, create an empty sandbox project on your server and follow these steps: Enable versioned settings for your project. id = "script.from.file.1" The goal of this post is to demonstrate an approach for building an existing application with Kotlin DSL. To identify a build configuration in a project based on the portable DSL, TeamCity uses the ID assigned to this build configuration in the DSL. Right-click on the pom.xml file and select Add as Maven Project – the IDE will import the Maven module and download the required dependencies. Downloading Settings in Kotlin. Hello! You can specify a default value of this parameter as an optional second argument: getParameter("", ""). When creating an empty project, that's what you see in settings.kts in your IDE: Here, project {} represents the current project whose settings you'll define in the DSL (in DSL code it is sometimes referenced as _Self). On the other hand, the id of an entity can be changed freely, if the uuid remains the same. object BuildC: buildType ({ Kotlin DSL API versions. Examining it, we can see that it has a series of classes that describe pretty much the entire TeamCity user interface. Solution: set the internal property teamcity.kotlinConfigsDsl.docsGenerationXmx=768m and restart the server. It’s also possible to achieve the same result with Java (or any JVM-based language). The Gradle Kotlin DSL provides support for writing Gradle build scripts using JetBrains' Kotlin language. Test Today we are wrapping up our .NET integration demo. TheKotlin tutorialhelps you learn most Kotlin features in a few hours. buildType(Test2) Enable versioned settings with the same VCS root and the Kotlin format again. Spring Petclinic is a Java project that uses Maven for the build. For instance, it is impossible to have a condition and change something depending on the current state of a build. buildChain.buildTypes().forEach { buildType(it) } uuid = "05acd964-b90f-4493-aa09-c2229f8c76c0" return bufferedReader.use { it.readText() }.trimIndent() * With the introduction of the Pipeline plugin, users now can implement a project’s entire build/test/deploy pipeline in a Jenkinsfile and store that alongside their code, treating their pipeline as another piece of code checked into source control. I am currently using the kotlin-dsl Gradle plugin 0.18.2, Kotlin 1.2.51 and Gradle 4.10.2 in my Android project (take a look at the temporary project-setup branch). } dependsOn(Extra) // extra dependency to be defined in all builds in the parallel block To generate a token for a secure value, follow this instruction. So when TeamCity generates portable Kotlin DSL scripts, it has to remove the parent project ID prefix from the IDs of all of the generated entities. In case of a non-portable DSL, patches are stored under the project patches directory of .teamcity: Working with patches is the same as in portable DSL: you need to move the actual settings from the patch to your script and remove the patch. Is it easy to copy over an existing build configuration’s “View As Kotlin DSL” to the KTS file? This is similar to the checks performed by TeamCity when you create a new build step in the UI. }, package MyProject WARNING! The new module is added to your project structure.\. The uuid is a unique identifier which associates a project, build configuration or VCS root with its data. I see the above warning wrapping the buildFeatures block where i enable dataBinding and more recent viewbinding features, my AS and gradle, ... android android-studio kotlin build.gradle gradle-kotlin-dsl. This task can be started from IDE (see Plugins | teamcity-configs | teamcity-configs:generate node in the Maven tool window), or from the command line: The result of the task execution will be placed under the .teamcity/target/generated-configs directory. buildType(Test2) Some users may also prefer code to configuring the builds with point-and-click via UI. buildType(Package) If existing Kotlin settings are detected, the wizard will suggest importing them.
