Jenkins pipeline - Remove @tmp folder

5
votes

I am using "Workspace Cleanup Plugin" to clean workspace after the job finishes. But still @tmp directory is not deleted.

Any way we can delete this @tmp folder using pipeline script.

It looks like a known issue as far as I see in Jira:

You failed to point out where you see this directory. When Project@tmp is found on the jenkins MASTER it is used if you Replay the Project pipeline. Deleting the directory would save space, but cause functional loss. - Steven the Easily Amused

I used custom workspace in Jenkins then deleteDir() will not delete @tmp folder.

So to delete @tmp along with workspace use following

pipeline {
    agent {
        node {
            customWorkspace "/home/jenkins/jenkins_workspace/${JOB_NAME}_${BUILD_NUMBER}"
        }
    }
    post {
        cleanup {
            /* clean up our workspace */
            deleteDir()
            /* clean up tmp directory */
            dir("${workspace}@tmp") {
                deleteDir()
            }
            /* clean up script directory */
            dir("${workspace}@script") {
                deleteDir()
            }
        }
    }
}

This snippet will work for default workspace also.

You can use deleteDir() as the last step of the pipeline Jenkinsfile (assuming you didn't change the working directory).

The following code snippet works great. 

//@tmp clean up
stage ('cleanup') 
{
  withEnv(['PATH+EXTRA=/usr/sbin:/usr/bin:/sbin:/bin']) {
  dir('<your directory path>') {
  sh "rm -rf <directory `enter code here`name>@tmp"
  }
  }
}

Not a direct answer to your question, but might help someone.

If you are using the dir Jenkins pipeline step to change directories, then you'll see these @tmp folders getting created. Instead, use the cd command and they won't get created in the first place.

So, instead of,

def myFunc(String folder) {
  dir(folder) {
   // work
  }
}

Do this.

def myFunc(String folder) {
  bat "cd ${folder}"
  // work
}
