How to clear workspace in Jenkins pipeline before job starts

问题

I need to clear workspace before build starts. I tried using cleanDir() in stages, but in the declarative pipeline, check out happens first and when stage with cleadDir runs, checked out code also gets cleared which is not desired. How can we clear the workspace before check out in the declarative pipeline?

回答1:

Use the means of your VCS, with Git run

git clean -fdx

Actually, I have to revise my answer based on recent changes to the pipeline plugins, e.g. GitHub Branch Source Plugin 2.2.0 with JENKINS-43507.

Besides the different branch discovery behaviours, which can be configured, one can now define additional steps to take, including Clean before checkout (and Clean after checkout):

The resulting output in the pipeline execution will then be

Cleaning workspace
  > git rev-parse --verify HEAD # timeout=10
Resetting working tree
 > git reset --hard # timeout=10
 > git clean -fdx # timeout=10

so, pretty close to the calling git clean yourself.

stage('Git') {
            steps {
                step([$class: 'WsCleanup'])
                checkout scm
            }
        }

the WsCleanup does the trick

A slightly different approach would be to use the stash step to stash your code first:

stash includes: 'src/**', name: 'source-code'

After that you can delete everything in your current Workspace. In a later stage you can simply unstash the source code again:

unstash 'source-code'

Another advantage of stash/unstash is that you can use it to share files between multiple jenkins nodes.

Something like this should work:

            env.WORKSPACE = pwd()
            sh "rm ${env.WORKSPACE}/* -fr"
