After you add, edit, or delete the parameters and click Save, TeamCity will reload the DSL configuration and apply the changed values to the project settings. 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. script { The following example shows how to use context parameters in DSL: Each context parameter is expected to have a value, either the default one, set in the DSL, or a project-specific one, set in the UI. version = "2020.2" org.gradle.api.artifacts.component. TheKotlin tutorialhelps you learn most Kotlin features in a few hours. We use Kotlin's property here to pass the property related to StringBuilder, as we use the power of extension functions in buildString function. Is it easy to copy over an existing build configuration’s “View As Kotlin DSL” to the KTS file? In this case the following error can be shown: Build configuration id '' should have a prefix corresponding to its parent project id: ''. }) The corresponding objects for VCS root and the build configuration are declared in the same script. In the DSL code, a build chain is declared inside a project by the sequential method that lists chained builds one by one. project { You can leverage all the functionalities of Kotlin in your Gradle file. /* disable the last build step depending on the value of the `environment` parameter */ }, import jetbrains.buildServer.configs.kotlin.v2019_2. teamcity-configs-maven-plugin Compared to a general guide we had in the past, the new documentation provides more details and offers better navigation between sections. buildType(BuildA) id("HelloWorld") Fix the URL in the Kotlin DSL in the version control and push the fix. For instance, it is impossible to have a condition and change something depending on the current state of a build. Thanks for the feedback. Let's take a look! In this tutorial, we'll see how powerful Kotlin language features can be used for building type-safe DSLs. buildType(HelloWorld) In this series of posts, we are going to explain how to use Kotlin to define build configurations for TeamCity. The Kotlin DSL API documentation is available at /app/dsl-documentation/index.html. However, the plugins you have installed on your TeamCity instance may provide the extensions for the DSL, and therefore our pom.xml needs to pull the dependencies from the corresponding server. import jetbrains.buildServer.configs.kotlin.v2019_2.buildSteps.script * steps { You will be redirected to the Attach Build History tab. Do not confuse Job DSL with Pipeline DSL, both have their own syntax and scope of application. You can refer to the configuration in the other project by the id, but you cannot obtain the instance. 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. You can create different entities in this project by calling vcsRoot(), buildType(), template(), or subProject() methods. To start working with Kotlin DSL, go to the project settings page, click the Actions menu and select Download settings in kotlin format, the option available since TeamCity 10.0.3.This will generate a .zip archive with project settings which can be used in your sandbox project.. All necessary dependencies will be resolved automatically right away. }), Storing Project Settings in Version Control. The Gradle Kotlin DSL provides support for writing Gradle build scripts using JetBrains' Kotlin language. The changes to the settings are then always reflected on the server. For the build configuration, there’s the View DSL toggle that would display the preview of the configuration in Kotlin format. Imports omitted, this is how the settings.kts for our demo project looks: version indicates the TeamCity version, and project() is the main entry point to the configuration script. For an existing project, changing Kotlin DSL settings of an existing source root doesn't take. However, since TeamCity 2019.2, it is possible to customize generation of project settings with help of DSL context parameters. }, project { uuid = "05acd964-b90f-4493-aa09-c2229f8c76c0" As a result, the new project will include one VCS root and a build configuration with a Maven build step and a VCS trigger. With context parameters, it is possible to maintain a single Kotlin DSL code and use it in different projects on the same TeamCity server. Problem: I want to generate a TeamCity build configuration based on the data in some file residing in the VCS inside the .teamcity directory. steps { For this, specify all the required credentials in the Maven settings file (mavenSettingsDsl.xml) and upload it on the Maven Settings page of the Root project. } Since TeamCity 2019.2, you can customize the DSL generation behavior using context parameters configured in the TeamCity UI. name = "Command Line Runner Test" Select a required VCS root. 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. ... https://dzone.com/articles/kotlin-dsl-from-theory-to-practice 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. Here are some: In some cases, Kotlin DSL might be slower than the Groovy one. import jetbrains.buildServer.configs.kotlin.v2019_2.buildSteps.script These IDs usually look like: _. To restore the builds' history after changing the build configuration ID, go to the Build Configuration Settings of the build configuration whose ID was changed, open the Actions menu, and click Attach build history. /* some comment text */ kts is a Kotlin Script file, different from a Kotlin file (.kt) in that it can be run as a script. password("", "credentialsJSON:") To keep your settings files neat, it is convenient to store lengthy code instructions in separate files. buildChain.buildTypes().forEach { buildType(it) } Select Modules under the Project Settings section. 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. In this tutorial you will use Gradle Kotlin DSL (GKD) in a new Kotlin project to script Gradle builds. The issue is though that currently the TeamCity DSL does not provide this functionality. val buildChain = sequential { buildType(Test2) Since Kotlin is statically typed, you automatically receive the auto-completion feature in an IDE which makes the discovery of available API options much simpler. } In Kotlin, we can find examples of DSL implementations in several libraries, for example Anko. }, import jetbrains.buildServer.configs.kotlin.v2019_2. filesCleanup = Swabra.FilesCleanup.DISABLED version = "2020.2" This format can still be enabled by turning off the Generate portable DSL scripts checkbox on the Versioned Settings page. } So I want to run two builds (A –> B) in a build chain. Enable versioned settings with the same VCS root and the Kotlin format again. }), params { The parent type of the object, GitVcsRoot, indicates that this is a git repository that we’re going to connect to. The generated settings layout is a .teamcity directory with two files: settings.kts and pom.xml. Creating NuGet packages Teamcity 10 – Configuration As Code With Kotlin DSL. If you are using IntelliJ IDEA, you can easily start debugging of any Maven task: Navigate to View | Tool Windows | Maven Projects. This API allows you to declaratively compose your graph in your Kotlin code, rather than inside an XML resource. 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. Open the folder in IntelliJ IDEA, you will see the following layout: Essentially, the .teamcity folder is a Maven module. } script { Kotlin DSL API versions. Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language).. Part 2: Testing and building projects I was able to locate the configs-dsl-kotlin-10.0.0.jar file and it resolved some of my reference problems. Job DSL can be used to create Pipeline and Multibranch Pipeline jobs. If existing Kotlin settings are detected, the wizard will suggest importing them. object BuildA: buildType ({ Some of the dependencies are downloaded from JetBrains’ own Maven repository. 2. But this will not work if not all of the project entities have this prefix in their IDs. }, params { For instance, the following are the files checked in to version control for the spring-petclinic application. There is not much use for the standard Maven project layout here. One of the advantages of the portable DSL script is that the script can be used by more than one project on the same server or more than one server (hence the name: portable). 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. All changes to the one project will be replicated to another. This project has already been built on the demo TeamCity server. 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. , project { org.gradle.api.artifacts.dsl. scriptContent = "echo Deploy" To display the hidden files and directories, press Command + Shift + . This is the main difference of the non-portable DSL format from portable. As stated earlier, DSLs (domain-specific languages) are "languages specialized to a particular application domain". buildType(Deploy) If there are many such IDs, use the Bulk edit IDs project action to change all of them at once. Then, before starting the generation process, the TeamCity server will fetch the necessary dependencies from the Maven repository, compile code with them, and then start the settings generator. } Code navigation between files becomes easy in Kotlin DSL. No, currently it is not possible. Creating our own Pipeline definition buildTypesOrder = arrayListOf(BuildC, BuildA, BuildB) For instance, instead of using TeamCity templates, one can create a function or class which will encapsulate project common settings. In Android, every tutorial teaching you the basics describe how to design screen through XML files. uuid is some unique sequence of characters. A general-purpose language, such as Kotlin or Java, on the other hand, can be used in multiple parts of one application. I strongly believe Transition X style DSL reduces complexity and simplifies workflow when working with transitions. This project ID and name can be accessed via a special DslContext object but cannot be changed via the DSL code. object HelloWorld: BuildType({ scriptContent = "echo 'Hello world!'" A is in repo RA and B is in repo RB in teamcity. For example. I’ll add a warning about it. buildType(Package) Once you enable Versioned Settings for the project, TeamCity will generate the corresponding files and immediately commit/push them into the selected repository. In the example above the id must be specified. swabra { password("pass-to-bucket", "credentialsJSON:12a3b456-c7de-890f-123g-4hi567890123") buildType(BuildC) 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. ... If you already have an IntelliJ IDEA project and want to add a Kotlin DSL module to it, follow related instructions. 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. script { Gradle Inc first announced GKD in May 17 2016. The goal of this post is to demonstrate an approach for building an existing application with Kotlin DSL. Referencing context parameters in DSL To reference a context parameter in the DSL code, use the getParameter() method of the DslContext object. Hello! With these settings, the build configurations will be displayed in the UI in the following order: C, A, B. app/dsl-documentation/index.html on our Teamcity server displays "Kotlin DSL API documentation is not initialized yet", OutOfMemoryError during TeamCity startup with org.jetbrains.dokka in stack trace. Disable versioned settings to enable the UI. After we tested and built our applications for different platforms, we can finally pack and deploy them! } If you omit it, there will be a validation error on an attempt to generate settings from this script. version = "2020.2" This is similar to the checks performed by TeamCity when you create a new build step in the UI. The &q, TeamCity REST API is a powerful tool which lets you integrate external applications with the TeamCity server and create diverse script interactions. 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. In Kotlin, infix helps us to create custom DSL similar to like how we write in English. Good call! All I need is to be able to run these two builds in the order A –> B. Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language). If the build history is important, it should be restored as soon as possible: after the deletion, there is a configurable timeout (5 days by default) before the builds of the deleted configuration are removed during the build history clean-up. ... For example, Spring configuration and Vaadin screen design allow both. }), val dataFile = File(DslContext.baseDir, "data/setup.xml"), project { 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. If all dependencies have been resolved, no errors in red will be visible in settings.kts. Or, fork the source repo and build the project yourself. Since TeamCity 2019.2.1, you can establish access to external libraries in private repositories. The following examples shows how to add a build configuration with a command line script: Here, id will be used as the value of the Build configuration ID field in TeamCity. To mark a DSL value as secure, you can assign it to a parameter of the password type: where is a unique name which can be used as a key for accessing the secure value via DSL (for example, in the File Content Replacer build feature); is the token corresponding to the target secure value. However, I appear to be missing a further subset of v10 classes that do not want to import? To fix this problem, change the ID of the affected entity. project { Try customizing your watch face even further using DSL by reviewing all the options in the model/AnalogWatchFaceStyleModels.kt class. Validation checks that the mandatory properties are specified, for example a build step like this: will produce a validation error saying that the mandatory path property is not specified. scriptContent = readScript("scripts\\test.sh") WARNING! This is the same project where you enabled versioned settings on the previous step. For beginners, it offers a quick start guide and describes common use cases. You can also perform validation locally by generating XML configuration files with help of generate task. Make sure it specifies correct credentials; TeamCity won't be able to commit changes if anonymous authentication is used. Managing context parameters in UI You can manage project context parameters on the Versioned Settings | Context Parameters tab. Jenkins Pipeline is often the better choice for creating complex automated processes. The Navigation component provides a Kotlin-based domain-specific language, or DSL, that relies on Kotlin's type-safe builders. The object is registered in the project using a buildType(...) function call. The uuid is a unique identifier which associates a project, build configuration or VCS root with its data. I want to be able to add dependencies and pass parameters to it. } // build chain definition: Wow. Could you describe your use case a little more in detail? https://kotlinlang.org/docs/reference/mpp-dsl-reference.html In TeamCity, we can use Kotlin DSL to author build configurations. 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. } For our demo project, TeamCity will detect the presence of the Maven pom.xml and propose the required build steps. import jetbrains.buildServer.configs.kotlin.v2019_2. 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. The result of scripts execution is configuration files, which are loaded by TeamCity server and then behavior of the newly triggered builds changes.
