To open the Kotlin DSL project in IntelliJ IDEA, open the .teamcity/pom.xml file as a project. All necessary dependencies will be resolved automatically right away. If all dependencies have been resolved, no errors in red will be visible in the settings.kts.
If you already have an IntelliJ IDEA project and want to add Kotlin DSL module to it, see this section.
Editing Kotlin DSL
If you created an empty project, that’s what you’ll see in your IDE when you open settings.kts:
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. 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.
View DSL in UIUI
There is an option in the UI to help those using Kotlin-based DSL. 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 (e.g. a build step, a trigger, dependencies) will be highlighted. To go back, click Edit in UI.
