Build Environment Variables

Table of Contents

When a Jenkins job executes, it sets some environment variables that you may use in your shell script, batch command, Ant script or Maven POM. The following table contains a list of all of these environment variables.

Environment Variable

  • BUILD_NUMBER

The current build number, such as "153"

  • BUILD_ID

The current build id, such as "2005-08-22_23-59-59" (YYYY-MM-DD_hh-mm-ss, defunct since version 1.597)

  • BUILD_URL

The URL where the results of this build can be found (e.g. http://buildserver/jenkins/job/MyJobName/666/)

  • NODE_NAME

The name of the node the current build is running on. Equals 'master' for master node.

  • JOB_NAME

Name of the project of this build. This is the name you gave your job when you first set it up. It's the third column of the Jenkins Dashboard main page.

  • BUILD_TAG

String of jenkins-${JOB_NAME}-${BUILD_NUMBER}. Convenient to put into a resource file, a jar file, etc for easier identification.

  • JENKINS_URL

Set to the URL of the Jenkins master that's running the build. This value is used by Jenkins CLI for example

  • EXECUTOR_NUMBER

The unique number that identifies the current executor (among executors of the same machine) that's carrying out this build. This is the number you see in the "build executor status", except that the number starts from 0, not 1.

  • JAVA_HOME

If your job is configured to use a specific JDK, this variable is set to the JAVA_HOME of the specified JDK. When this variable is set, PATH is also updated to have $JAVA_HOME/bin.

  • WORKSPACE

The absolute path of the workspace.

  • SVN_REVISION

For Subversion-based projects, this variable contains the revision number of the module. If you have more than one module specified, this won't be set.

  • CVS_BRANCH

For CVS-based projects, this variable contains the branch of the module. If CVS is configured to check out the trunk, this environment variable will not be set.

  • GIT_COMMIT

For Git-based projects, this variable contains the Git hash of the commit checked out for the build (like ce9a3c1404e8c91be604088670e93434c4253f03) (all the GIT_* variables require git plugin)

  • GIT_URL

For Git-based projects, this variable contains the Git url (like git@github.com:user/repo.git or [https://github.com/user/repo.git])

  • GIT_BRANCH

For Git-based projects, this variable contains the Git branch that was checked out for the build (normally origin/master)
