    • Jenkins 1.598
      Workflow Plugins 1.2

      Steps to Reproduce:
      1) Create a new workflow job that pulls from git and is set to poll scm infrequently (as appropriate for using scm hooks).
      2) Run the job once manually.
      3) Trigger an scm poll by invoking jenkins-url/git/notifyCommit with appropriate query string.

      Result: Status 200 & Body of response states that polling of the test job was scheduled.

      4) Restart Jenkins (sudo service jenkins restart or similar)
      5) After Jenkins returns to normal running status repeat step 3.

      Result: Status 500 and the stack trace appended to the end of this report.

      6) Run the job again manually (step 2).
      7) Repeat Step 3.

      Result: Status 200 & Body of response states that polling of the test job was scheduled.

      In summary, scm triggers fail post-jenkins restart for workflow jobs until each such job is run once. I did not thuroughly test with multiple jobs but I believe it is the case that every workflow job must be run manually before any job (even non-workflow) can be triggered.

          Description Original: Steps to Reproduce:
          1) Create a new workflow job that pulls from git and is set to poll scm infrequently (as appropriate for using scm hooks).
          2) Run the job once manually.
          3) Trigger an scm poll by invoking jenkins-url/git/notifyCommit with appropriate query string.

          Result: Status 200 & Body of response states that polling of the test job was scheduled.

          4) Restart Jenkins (sudo service jenkins restart or similar)
          5) After Jenkins returns to normal running status repeat step 3.

          Result: Status 500 and the stack trace appended to the end of this report.

          6) Run the job again manually (step 2).
          7) Repeat Step 3.

          Result: Status 200 & Body of response states that polling of the test job was scheduled.

          In summary, scm triggers fail post-jenkins restart for workflow jobs until each such job is run once.

          In summary, scm triggers fail post-jenkins restart for workflow jobs until each such job is run once. I did not thuroughly test with multiple jobs but I believe it is the case that _every_ workflow job must be run manually before _any_ job (even non-workflow) can be triggered.

          Description Original: Steps to Reproduce:
          1) Create a new workflow job that pulls from git and is set to poll scm infrequently (as appropriate for using scm hooks).
          2) Run the job once manually.
          3) Trigger an scm poll by invoking jenkins-url/git/notifyCommit with appropriate query string.

          Result: Status 200 & Body of response states that polling of the test job was scheduled.

          4) Restart Jenkins (sudo service jenkins restart or similar)
          5) After Jenkins returns to normal running status repeat step 3.

          Result: Status 500 and the stack trace appended to the end of this report.

          6) Run the job again manually (step 2).
          7) Repeat Step 3.

          Result: Status 200 & Body of response states that polling of the test job was scheduled.

          In summary, scm triggers fail post-jenkins restart for workflow jobs until each such job is run once. I did not thuroughly test with multiple jobs but I believe it is the case that _every_ workflow job must be run manually before _any_ job (even non-workflow) can be triggered.

          Hmm, will see if I can reproduce in a test. WorkflowRun.checkouts is not transient and is only ever set to a non-null value when the build begins, but I am guessing onLoad fails to set it, implying that this should actually be a RunAction2 or something. 81a052f dealt with a variant NPE.

          Independently, GitStatus.doNotifyCommit ought to catch RuntimeException in a listener, warn, and continue.

          If reproducible, this on its own merits a 1.3 release.

          Was not able to reproduce. Using Linux and Java 8, I ran 1.598 from the WAR with a fresh home directory, installed Workflow plugins (1.2), added the Git plugin (2.3.5), restarted Jenkins to complete the installation. Created a new Git repository /tmp/testrepo, added one file to it and committed. Defined a job

          <?xml version='1.0' encoding='UTF-8'?>
          <flow-definition plugin="workflow-job@1.2">
            <actions/>
            <description></description>
            <keepDependencies>false</keepDependencies>
            <properties/>
            <definition class="org.jenkinsci.plugins.workflow.cps.CpsFlowDefinition" plugin="workflow-cps@1.2">
              <script>node {
            git &apos;/tmp/testrepo&apos;
            sh &apos;ls&apos;
          }</script>
              <sandbox>false</sandbox>
            </definition>
            <triggers>
              <hudson.triggers.SCMTrigger>
                <spec>@daily</spec>
                <ignorePostCommitHooks>false</ignorePostCommitHooks>
              </hudson.triggers.SCMTrigger>
            </triggers>
          </flow-definition>
          

          Ran a build; it checked out the repo as expected and listed the one file.

          From a shell, ran

          $ curl -i http://localhost:8080/jenkins/git/notifyCommit?url=/tmp/testrepo
          HTTP/1.1 200 OK
          Triggered: http://localhost:8080/jenkins/job/<JOBNAME>/

          as expected.

          Restarted Jenkins (/restart), and when it was back up, ran the same curl command again, with the same result.

          Also committed a change to the Git repo and ran the notify command. Again the same curl output, and now build #2 of the job was triggered, with the expected changelog.

          If you can still reproduce this problem, please attach $JENKINS_HOME/jobs/$JOBNAME/builds/lastSuccessfulBuild/build.xml. There should be a section beginning

          <checkouts class="linked-list">
          

          Your stack trace suggests that it is missing for some reason, but I am not sure how that could have happened.

          Jesse Glick added a comment - Was not able to reproduce. Using Linux and Java 8, I ran 1.598 from the WAR with a fresh home directory, installed Workflow plugins (1.2), added the Git plugin (2.3.5), restarted Jenkins to complete the installation. Created a new Git repository /tmp/testrepo , added one file to it and committed. Defined a job <?xml version= '1.0' encoding= 'UTF-8' ?> <flow-definition plugin= "workflow-job@1.2" > <actions/> <description> </description> <keepDependencies> false </keepDependencies> <properties/> <definition class= "org.jenkinsci.plugins.workflow.cps.CpsFlowDefinition" plugin= "workflow-cps@1.2" > <script> node { git &apos;/tmp/testrepo&apos; sh &apos;ls&apos; } </script> <sandbox> false </sandbox> </definition> <triggers> <hudson.triggers.SCMTrigger> <spec> @daily </spec> <ignorePostCommitHooks> false </ignorePostCommitHooks> </hudson.triggers.SCMTrigger> </triggers> </flow-definition> Ran a build; it checked out the repo as expected and listed the one file.
