}, import jetbrains.buildServer.configs.kotlin.v2019_2. buildType(Package) } 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). * buildChain.buildTypes().forEach { buildType(it) } Understanding DSL. // build chain definition: You can refer to them by their relative paths. If all dependencies have been resolved, no errors in red will be visible in settings.kts. But if generated files were changed, then TeamCity will have to produce a patch, since it no longer knows what part of .kt or .kts file should be changed. Part 2: Testing and building projects The vcsRoot(...) function call registers a predefined VCS root to the project. return bufferedReader.use { it.readText() }.trimIndent() }), val dataFile = File(DslContext.baseDir, "data/setup.xml"), project { You can sign in as a guest and explore the build results. When viewing your build configuration settings in the UI, you can click View DSL in the sidebar: the DSL representation of the current configuration will be displayed and the setting being viewed (for example, a build step, a trigger, dependencies) will be highlighted. Context parameters are specified as a part of the project versioned settings in the UI. org.gradle.api. In TeamCity, we can use Kotlin DSL to author build configurations. The TeamCity server does not use Maven for generating settings from your DSL scripts, so the generation of settings on the server will not be affected if you commit pom.xml containing context parameters back to the repository. To keep your settings files neat, it is convenient to store lengthy code instructions in separate files. This is the main difference of the non-portable DSL format from portable. Basically, a DSL is a language that focuses on just one particular part of an application. In Android, every tutorial teaching you the basics describe how to design screen through XML files. It’s also possible to achieve the same result with Java (or any JVM-based language). All I need is to be able to run these two builds in the order A –> B. When you create a project from DSL or update the project versioned settings, TeamCity detects all context parameters with missing values and prompts you to set them. The source directory is also redefined in this pom.xml since in many cases there will be just one settings.kts file. DSL scripts do not have direct control on how builds are executed. Today we are wrapping up our .NET integration demo. The next step for this project is transitioning to configuration-as-code with Kotlin DSL. Here are some: In some cases, Kotlin DSL might be slower than the Groovy one. Kotlin DSL for Kubernetes configs. To use an external library in your Kotlin DSL code, add a dependency on this library to the .teamcity/pom.xml file in the settings repository and commit this change so that TeamCity detects it. If you already have an IntelliJ IDEA project and want to add a Kotlin DSL module to it, follow related instructions. Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language).. Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language). The VCS root object, PetclinicVcs, is a very simple one in our example. add { If you are writing your source code in Kotlin then it is good to have your build scripts in Kotlin as well. name = "Hello world" } If existing Kotlin settings are detected, the wizard will suggest importing them. 17 Mar 2017 | Jeffrey Palermo. 2. This format can still be enabled by turning off the Generate portable DSL scripts checkbox on the Versioned Settings page. inside the file chooser. The aim of this library is to increase exposure to the Transition framework and unlock their potential using Kotlin’s language features. } Basically, it represents a Project instance which generates project settings. For the build configuration, there’s the View DSL toggle that would display the preview of the configuration in Kotlin format. Select the detached build history and click Attach. Enable versioned settingsfor your project. Kotlin DSL. }, fun readScript(path: String): String { Open the folder in IntelliJ IDEA, you will see the following layout: Essentially, the .teamcity folder is a Maven module. There is not much use for the standard Maven project layout here. If DSL scripts were not changed manually, that is if they were generated by TeamCity and stay the same way in the repository, then changes via the web UI will be applied directly to these generated files. * The generated settings layout is a .teamcity directory with two files: settings.kts and pom.xml. org.gradle.api.artifacts.dsl. Defining this at the `Project.kt` level in our DSL, would give us a good oversight of what’s taking place. Is it easy to copy over an existing build configuration’s “View As Kotlin DSL” to the KTS file? These IDs usually look like: _. If there are many such IDs, use the Bulk edit IDs project action to change all of them at once. Maybe we can find a workaround. 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. Test However, I appear to be missing a further subset of v10 classes that do not want to import? The Build object inherits from the BuildType class that represents the build configuration in TeamCity. Bundles Kotlin 1.x Standard Library for JDK 8. The goal of this post is to demonstrate an approach for building an existing application with Kotlin DSL. The issue is though that currently the TeamCity DSL does not provide this functionality. The benefits of this approach include versioning support via VCS repository, a simplified audit of the configuration changes, and improved portability of the configurations. But this will not work if not all of the project entities have this prefix in their IDs. Solution: In your existing project in IntelliJ IDEA: Go to File | Project Structure, or press Ctrl+Shift+Alt+S. }), Storing Project Settings in Version Control. 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. /* a context parameter that defines a build configuration name; its default value is `Test Build` */ sequential { The portable format does not require specifying the uuid, but if it happened so that a build configuration lost its history (for example, on changing build configuration external id) you can reattach the history to the build configuration using the Attach build history option from the Actions menu. In this case the following error can be shown: Build configuration id '' should have a prefix corresponding to its parent project id: ''. I cannot directly set dependency of B as A in repo RB because it’s a generic build. }, object CommandLineRunnerTest : BuildType({ /* disable the last build step depending on the value of the `environment` parameter */ buildTypesOrder = arrayListOf(BuildC, BuildA, BuildB) To go back, click Edit in UI. https://kotlinlang.org/docs/reference/mpp-dsl-reference.html 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. The real-life project that I converted to Kotlin DSL containsseveral micro-services, each uses the Application plugin to create an executable,and jib plugin is used to generate Docker images.We reuse the code via a Gradle ad-hocplugin to avoid duplicating scripts.The patternhelps to reuse the same Gradle (Groovy) code, the usage of whichfor every micro-service is like: The ad-hoc plugin is applied via a project.subprojects.forEac… This is similar to the checks performed by TeamCity when you create a new build step in the UI. filesCleanup = Swabra.FilesCleanup.DISABLED In TeamCity 2018.x Kotlin support was greatly improved for a more pleasant user experience. /* ... */ Hence, there will be 2 VCS roots in the project: one for source code of the application and the other for build settings. Using the version control-stored DSL enables you to define settings programmatically. The Kotlin DSL files producing build configurations and VCS roots are placed under the corresponding subdirectories. When creating the project from a repository URL, TeamCity will scan the sources. }), changeBuildType(RelativeId("SampleProject_Build")) { // this part finds the build configuration where the change has to be done Infix helps us to create Pipeline and Multibranch Pipeline jobs and authentication type if needed of...
