"ERROR: missing workspace" and chaining builds

[Vincent Massol]

Hi guys,

I regularly get the following errors in our Jenkins pipeline on XWiki:

ERROR: missing workspace /home/hudsonagent/jenkins_root/workspace/XWiki_xwiki-platform_master-ZGNMAWOYB6APYNMYWF7HH475RM4M6C6RE2U76Y5M5RWNQJWOLFGA on agent-2-1

[main] Caused by: java.io.IOException: /home/hudsonagent/jenkins_root/workspace/XWiki_xwiki-platform_master-ZGNMAWOYB6APYNMYWF7HH475RM4M6C6RE2U76Y5M5RWNQJWOLFGA/xwiki-platform-core/xwiki-platform-flamingo/xwiki-platform-flamingo-themes/xwiki-platform-flamingo-theme-test/xwiki-platform-flamingo-theme-test-tests/target/xwiki doesn't exist.

Our Jenkins file does this:

stage ('Platform Builds') {
  parallel(
    'main': {
      build(
        name: 'Main',
        goals: 'clean deploy',
        profiles: 'legacy,integration-tests,office-tests,snapshotModules',
        properties: '-Dxwiki.checkstyle.skip=true -Dxwiki.surefire.captureconsole.skip=true -Dxwiki.revapi.skip=true'
      )
      build(
        name: 'Distribution',
        goals: 'clean deploy',
        profiles: 'legacy,integration-tests,office-tests,snapshotModules',
        pom: 'xwiki-platform-distribution/pom.xml'
      )
      build(), ...
  }, ...

(Full file here: https://github.com/xwiki/xwiki-platform/blob/40cf4cf65e73728d53ee30ffcabd1534640dc9c5/Jenkinsfile#L26 )

And build() is running Maven on a node() (xwikiBuild() is pipeline library running Maven):

def build(map)
{
  node {
    xwikiBuild(map.name) {
...
    }

  }
}

In this situation, do you see any reason for Jenkins to delete a workspace on "main" and a reason for each node() call to not request a new workspace? So in short I guess I'm asking for some clarification on when workspaces are initialized.

Thanks!

Could it be that the workspace is deleted once the node() ends and that it happens that some other node() calls happen to run on the same node and that Jenkins would allocate a workspace only once per job? That would be strange though.

Thanks

Hi Vincent,

 

does it work most of the times? If so, could it be related to https://issues.jenkins-ci.org/browse/JENKINS-27329 “WorkspaceCleanupThread may delete workspaces of running jobs”?

Indeed it works most of the time and the problem only happens from time to time. The issue you reference could well be the cause, thanks for pointing it (I'll try to workaround mentioned in it).

Thanks

Note that we're having this problem only since we moved to pipeline.

Thanks

Hi Vincent

I got this problem on pipeline deployment , says ERROR : Missing Workspace and failed the job which is very annoying.

Were you able to figure out the fix or any workaround ? any help would be much appreciated.

Thanks

Hi Rashi,

 

If it happened/happens sporadically and you have Jenkins < 2.125 it may be related to https://issues.jenkins-ci.org/browse/JENKINS-27329
