buildType(BuildA) 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). If you are using IntelliJ IDEA, you can easily start debugging of any Maven task: Navigate to View | Tool Windows | Maven Projects. A is in repo RA and B is in repo RB in teamcity. The &q, TeamCity REST API is a powerful tool which lets you integrate external applications with the TeamCity server and create diverse script interactions. Hence, there will be 2 VCS roots in the project: one for source code of the application and the other for build settings. We can also create custom DSL using, Infix. For example, Spring configuration and Vaadin screen design allow both. https://kotlinlang.org/docs/reference/mpp-dsl-reference.html 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. Solution: set the internal property teamcity.kotlinConfigsDsl.docsGenerationXmx=768m and restart the server. The changes to the settings are then always reflected on the server. git clone https://github.com/antonarhipov/spring-petclinic-teamcity-dsl.git. Does Kotlin have tools to change its syntax to create APIs that are more suitable for the problem? For our example, we'll create a simple tool for constructing SQL queries, just big enough to illustrate the concept. Regardless of whether you are starting from scratch or you have an existing project. Example of a Maven plugin with context parameters: This is useful if you want to verify locally that your DSL scripts produce settings correctly for different values of DSL context parameters. 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. ... In Android, every tutorial teaching you the basics describe how to design screen through XML files. Creating NuGet packages buildType(Test2) 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. swabra { For those who have programming skills it allows for more natural reuse of build configuration settings. First, create a new project in TeamCity by pointing to a repository URL. If there are no errors during the script execution, you should see a build configuration named "Hello world" in your project. buildType(BuildC) script { Context parameters are specified as a part of the project versioned settings in the UI. buildType(Deploy) Check out the blog post series on using Kotlin DSL in TeamCity. project(MyProjectId.Project), package MyPackage However, one of the reasons why portable DSL is called portable is because the same settings.kts script can be used to generate settings for two different projects even on the same server. steps { Could you describe your use case a little more in detail? 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. 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. }), changeBuildType(RelativeId("SampleProject_Build")) { // this part finds the build configuration where the change has to be done I need the result of B reported back in RA so that if B is not successful, the pull request in RA should fail. Examining it, we can see that it has a series of classes that describe pretty much the entire TeamCity user interface. parallel (options = { onDependencyFailure = FailureAction.CANCEL }) { // non-default snapshot dependency options Point TeamCity to your repository, and it will detect the .teamcity directory and offer to import settings from there: It seems pointless to keep two projects using the same DSL scripts on one server, as such projects will be identical. For our demo, however, we are going to use a specific VCS root dedicated to only the settings. The DSL API version is encoded into the package name, for example: jetbrains.buildServer.configs.kotlin.v2019_2 The version part there corresponds to TeamCity version when this DSL API was introduced. 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. Kotlin DSL. Kotlin is a great general purpose programming language, you can use it to develop applications for almost any kind of platform. You will be redirected to the Attach Build History tab. The Gradle Kotlin DSL provides support for writing Gradle build scripts using JetBrains' Kotlin language. 17 Mar 2017 | Jeffrey Palermo. This Kotlin tutorial helps quickly learn most Kotlin features. * So I want to run two builds (A –> B) in a build chain. 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. There is not much use for the standard Maven project layout here. After we tested and built our applications for different platforms, we can finally pack and deploy them! In this tutorial, we'll see how powerful Kotlin language features can be used for building type-safe DSLs. There are several domain-specific languages that we’re already familiar with, like … import jetbrains.buildServer.configs.kotlin.v2019_2. 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. For example. I was able to locate the configs-dsl-kotlin-10.0.0.jar file and it resolved some of my reference problems. 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. But, there are a few disadvantages also. Job DSL can be used to create Pipeline and Multibranch Pipeline jobs. ... Click the plus sign, select Import module and choose the folder containing your project settings. Maybe we can find a workaround. The declarations in the object are self-explanatory: you can see the name of the build configuration, artifact rules, the related VCS root, build steps, and triggers. import jetbrains.buildServer.configs.kotlin.v2019_2.buildSteps.script It is possible to import existing Kotlin settings. script { * buildType(Test1) script { 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. 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. name = "Hello world" Finally, we will take a look at advanced topics such as extending the DSL. DSL is also good in case when you need to have a big amount of similar build configurations. } For the build configuration, there’s the View DSL toggle that would display the preview of the configuration in Kotlin format. The next step for this project is transitioning to configuration-as-code with Kotlin DSL. 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. Using the version control-stored DSL enables you to define settings programmatically. /* some comment text */ You can refer to the configuration in the other project by the id, but you cannot obtain the instance. Gradle Inc first announced GKD in May 17 2016. The uuid is a unique identifier which associates a project, build configuration or VCS root with its data. Question: How to add the .teamcity settings directory as a new module to an existing project in IntelliJ IDEA? A general-purpose language, such as Kotlin or Java, on the other hand, can be used in multiple parts of one application. As a result of this change, the build configuration will not contain the builds' history anymore. buildType(Package) 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). The settings using the DSL API version v2017_2+ are validated during DSL execution on the TeamCity server. Spring Petclinic is a Java project that uses Maven for the build. Kotlin DSL API versions. All I need is to be able to run these two builds in the order A –> B. Make sure it specifies correct credentials; TeamCity won't be able to commit changes if anonymous authentication is used. }, object CommandLineRunnerTest : BuildType({ You can sign in as a guest and explore the build results. buildType(Compile) The Kotlin DSL files producing build configurations and VCS roots are placed under the corresponding subdirectories. 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… If all dependencies have been resolved, no errors in red will be visible in settings.kts. Click Applyand TeamCity will commit the settings to your repository. 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. val bufferedReader: BufferedReader = File(path).bufferedReader() Select Kotlin as the format. Once you enable Versioned Settings for the project, TeamCity will generate the corresponding files and immediately commit/push them into the selected repository. /* ... */ 3. inside the file chooser. uuid = "05acd964-b90f-4493-aa09-c2229f8c76c0" There are more possibilities that we can use, which we will cover in further posts. Let's take a look! // register all build configurations, referenced in the chain, in the current project: name = "Hello world" 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. org.gradle.api.artifacts.component. 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. 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. The result of scripts execution is configuration files, which are loaded by TeamCity server and then behavior of the newly triggered builds changes. 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. buildType(BuildB) This format can still be enabled by turning off the Generate portable DSL scripts checkbox on the Versioned Settings page. Select Modules under the Project Settings section. The new DSL API version is usually introduced when there are significant incompatible changes in DSL API. The issue is though that currently the TeamCity DSL does not provide this functionality. However, I appear to be missing a further subset of v10 classes that do not want to import? The VCS root selected to store the settings can be the same as the source code of the application you want to build. Disable versioned settings to enable the UI. enabled = DslContext.getParameter(name = "Environment") != "Staging" 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. Select the detached build history and click Attach. } The Configuration as Code plugin can be used to manage the global system configuration of Jenkins. version = "2020.2" }) This is the main difference of the non-portable DSL format from portable. buildType { Good call! 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. buildType(Compile) This is the same project where you enabled versioned settings on the previous step. He’s very passionate about learning new things as often as possible and a self-appointed Kotlin … name = "Command Line Runner Test" Contribute to fkorotkov/k8s-kotlin-dsl development by creating an account on GitHub. Note: DSL scripts is essentially another way of writing TeamCity configuration files. We recommend keeping this ID constant, so the changes made in the DSL code are consistently applied to the respective build configuration in TeamCity. For beginners, it offers a quick start guide and describes common use cases. buildType(Test1) parentId("MyParent") Patches generation allows you to continue using the user interface for editing of the project settings and at the same time use the benefits of Kotlin DSL scripts. asked Aug 6 at 11:46. In the example above the id must be specified. Bundles Kotlin 1.x Standard Library for JDK 8. 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. 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). For example, Such auxiliary scripts can be put in the .teamcity directory alongside the settings files. import jetbrains.buildServer.configs.kotlin.v2019_2. The only way to restore the data is to revert the uuid to the original value. DSL scripts do not have direct control on how builds are executed. In this series, we've been explaining how TeamCity can integrate with .NET and walking you through a tutorial. Now we can pull the changes from the settings repository and start editing. kotlin We explored the main components of a TeamCity configuration script and its dependencies. Try customizing your watch face even further using DSL by reviewing all the options in the model/AnalogWatchFaceStyleModels.kt class. It is a function call, which takes as a parameter a block that represents the entire TeamCity project. } On the other hand, the id of an entity can be changed freely, if the uuid remains the same. We plan to describe more popular cases and explore advanced topics in the future. object Project : Project({ org.gradle.api.artifacts.ivy. It is best to add a Kotlin DSL configuration to an existing project in TeamCity. To keep your settings files neat, it is convenient to store lengthy code instructions in separate files. Is it easy to copy over an existing build configuration’s “View As Kotlin DSL” to the KTS file? You can also extend the validation in a way relevant for your setup. name = "${DslContext.getParameter("BuildName", "Test Build")}" Managing context parameters in UI You can manage project context parameters on the Versioned Settings | Context Parameters tab. The TeamCity specific classes that we use in the Kotlin script are coming from the dependencies that we declare in the pom.xml as part of the Maven module. The object is registered in the project using a buildType(...) function call. See the documentation on the public TeamCity server as an example. The buildType(...) function registers a build configuration. Is it possible to get BuildType if extId (or buildTypeId) is known? Alternatively, you can register all listed builds after the chain declaration with a simplified syntax: Explicit snapshot dependencies can be defined via a dependsOn() statement within both parallel and sequential blocks, with an optional lambda argument that allows setting dependency options. password("", "credentialsJSON:") Using the version control-stored DSL enables you to define settings programmatically. 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. Updating Android studio project and migrating to Kotlin dsl. In addition to this, it is possible to define which settings to take when the build starts. Non-default values of options for implicit snapshot dependencies can be set via the options lambda argument of any block. Problem: I want to generate a TeamCity build configuration based on the data in some file residing in the VCS inside the .teamcity directory. target/generated-configs TeamCity Kotlin DSL provides an alternative way to configure a build chain in a pipeline style. object BuildC: buildType ({ Since these IDs must be unique, there cannot be two different entities in the system with the same ID. } Besides storing settings in version control in XML format, TeamCity allows storing the settings in the DSL (based on the Kotlin language)..
