             Summary: Jenkins cleanup script can delete the current build's directory
                 Key: ISPN-9488
                 URL: https://issues.jboss.org/browse/ISPN-9488
             Project: Infinispan
          Issue Type: Bug
          Components: CI
    Affects Versions: 9.4.0.CR1
            Reporter: Dan Berindei
            Assignee: Dan Berindei
            Priority: Critical
             Fix For: 9.4.0.Final


Our {{Jenkinsfile}} runs {{cleanup.sh}} (provisioned on each agent via Ansible) to make room for the new build. The idea is to keep the checked-out sources after a build, so that the next build for the same branch is faster, and {{cleanup.sh}} only deletes the workspace directories of old builds if there's less than 10gb of free space. 

There is a problem, however: the agent may have less than 10GB of free space after deleting all the old workspace directories, and {{cleanup.sh}} will happily delete the current build's workspace to make more room. Obviously, the build fails afterwards:

{noformat}
ERROR: missing workspace /home/infinispan/workspace/Infinispan_PR-6236-6TTBGFU5OA5XZXKEPJRZI245GOIWTNAUH3HC5M6B36G25UNJPTCA on rhos-infinispan-slave-4.localdomain
{noformat}

Unfortunately we also use `returnOutput: true` when running the cleanup script, so it's not obvious who is deleting the build directory.
