org.jenkinsci.plugins.workflow.cps.steps.ParallelStepException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • In out pipeline we at first build multiple upstream Maven projects and then build the main project. Upstream projects are build in parallel: {code:java} parallel( projA: { projects.buildDependency('projA') }, projB: { projects.buildDependency('projB') } ... ) {code} projects.buildDependency() just checks-out each project from SVN and starts Maven build. The problem is that we often (in about 20% of builds) have errors caused by concurrent / parallel SVN check-outs. Sometimes it is ConcurrentModificationException and sometimes "SAXParseException: changelog11.xml; lineNumber: 1; columnNumber: 1; Premature end of file". See stacktraces below. As a temporary workaround we added {noformat} sleep time: random.nextInt(1000), unit: 'MILLISECONDS' {noformat} just before the checkout step to introduce time shifts between check-outs. We used random numbers because we were not sure if some local or env counter variable would be thread-safe in case of parallel steps. Now error happens only if time difference between check-outs is narrow, e.g. 5 milliseconds if 2 generated random numbers are close. Would it be possible to make Pipeline plug-in more resilient in case of parallel check-outs? {noformat} Caused by: org.jenkinsci.plugins.workflow.cps.steps.ParallelStepException: Parallel step projA
