Automation Environment Variables

In your automation script, you have access to a number of Automation environment variables. Use these variables to get data about your execution context: current Git branch name and Git revision number, Space URL, and so on. Don't confuse Automation environment variables with the container environment variables (set with job.container.env ).

If you run Kotlin code inside the kotlinScript block, you can get variable values directly or using the API commands:

job("Example") { container("openjdk:11.0.3-jdk") { kotlinScript { api -> println("Project key: " + System.getenv("JB_SPACE_PROJECT_KEY")) println("Project key: " + api.projectKey()) } } }

When does Automation resolve environment variables

The work of an Automation script consists of two phases:

  1. Script compilation: Automation checks the .space.kts file for errors and compiles the necessary script parts. This phase is performed in a separate container that cannot be anyhow accessed from within the script. Automation environment variables are not resolved on this phase.

  2. Script run: Automation runs the content of kotlinScript , shellScript , and docker.beforeBuildScript in a container. On this phase, Automation environment variables are resolved inside the specified container. This means that you can access Automation environment variables only inside the kotlinScript, shellScript, and beforeBuildScript items .


Variable API method Description
JB_SPACE_API_URL spaceUrl(): String The URL of your JetBrains Space instance. For example:


Variable API method Description
JB_SPACE_CLIENT_ID JB_SPACE_CLIENT_SECRET spaceClientId(): String spaceClientSecret(): String Temporary OAuth 2.0 credentials issued to the current script. The script uses them to authenticate in various Space modules. For example, you may need them to authenticate in a Packages repository in order to publish script artifacts.

Project settings

Variable API method Description
JB_SPACE_GIT_REVISION gitRevision(): String The current Git revision number
JB_SPACE_GIT_BRANCH gitBranch(): String The current Git branch name
JB_SPACE_PROJECT_ID projectId(): String The ID of the current project
JB_SPACE_PROJECT_KEY projectKey(): String The key of the current project
JB_SPACE_GIT_REPOSITORY_NAME gitRepositoryName(): String The name of the current Git repository (the one that contains the currently running .space.kts file)


Variable API method Description
JB_SPACE_EXECUTION_NUMBER executionNumber(): String The current build number. For example, you can use it to generate application version number. Learn more

Example. Use environment variables to generate a product version

For example, you want to generate a Docker container tag based on the current branch name and the job run number like version-0.123-mybranch:

job("Build and push image") { docker { beforeBuildScript { // Create an env variable BRANCH, // use env var to get full branch name, // leave only the branch name without the 'refs/heads/' path content = """ export BRANCH=${'$'}(echo ${'$'}JB_SPACE_GIT_BRANCH | cut -d'/' -f 3) """ } build { context = "docker" file = "./docker/Dockerfile" } push("") { // Use the BRANCH and JB_SPACE_EXECUTION_NUMBER env vars tag = "version-0.\$JB_SPACE_EXECUTION_NUMBER-\$BRANCH" } } }
