Preserve Jenkins workspace

问题

I have Jenkins set up to run concurrent builds, so I end up with workspace, workspace@2, workspace@3, etc. If Jenkins thinks the build is finished, a new build will overwrite the workspace. Is there a way of occasionally preventing that? E.g. Don't overwrite workspace@3 until I say. We have various scenarios where this would be very useful.

You could simply archive the complete workspace at the end of a build. It would then get deleted when the job is deleted.

To do this:

Add post-build action -> "Archive the artifacts"
Enter ** as "Files to archive"

If you want to make that configurable per run, you could create a build parameter:

(enable "This is a parametrized build" if not yet enabled)
add parameter of type "Choice Parameter" and name it ARCHIVE
with choices being <blank line> and ** (literally, put a blank first line, then second line is exactly **. No quotes)
use ${ARCHIVE} as "Files to archive" in "Advanced" setting of "Archive the Artifacts" action
enable checkbox "Do not fail build if archiving returns nothing"

You can define the agent in the hole pipeline, so the jenkins will use only the "workspace" dir.

For example (this is a NOT WORKING example):

pipeline {
    agent any 
    environment {
        // Environment variables
    }    
    stages {
        stage('Clear dir') {
            steps {
                deleteDir()
            }
        }
        stage('Make checkout') {
            agent any    // **THIS IS WRONG!!!!** 
            steps {
                echo 'Making checkout'
            }
        }
    } 
}

In the previous example, the "agent any" inside the stage will allow jenkins to create a "workspace@2" folder.

To prevent this, leave the agent only in the pipeline. Correct example:

pipeline {
    agent any   // This is right! leave only this mention of agent 
    environment {
        // Environment variables
    }    
    stages {
        stage('Clear dir') {
            steps {
                deleteDir()
            }
        }
        stage('Make checkout') {
            steps {
                echo 'Making checkout'
            }
        }
    } 
}

Jenkins stores current workspace as an environment ${WORKSPACE} variable. You can rename it at any moment of the job as long as you also set the renamed absolute directory path to ${WORKSPACE} variable within the build. When to do that is your choice now.

Another option is to schedule a downstream job and pass the ${WORKSPACE} to that job as parameter so that you can rename it.

This answer comes a bit late and probably not totally correct answer to your question, but this is the first ticket which I found when searching solution for my problem.

I had problem with having two folders JobName_XXXX and JobName_XXXX@2. At first my build worked well and I added parallel build for another Jenkins node. After I removed the parallel build, I encountered problem with build. It did not anymore work. I used blueocean's pipeline editor to create Jenkinsfile. By removing the parallel build I set "agent: any" to each step. It caused jenkins to reset scm inside the step. So I could not use previous steps' build results and build crashed. Solution was to remove "agent: any" from steps/stages. It is ok to have agent: any; directly inside the pipeline. With pipeline editor you cant remove those "agent: any" things -- at least not now? So edit Jenkinsfile manually.
