Title: Message Title

Yoram Michaeli created an issue   Jenkins / JENKINS-50307 While running in parallel for a loop, the index is wrong for each iteration Issue Type: Bug Assignee: Unassigned Attachments: Jenkinsfile Components: pipeline Created: 2018-03-21 04:20 Labels: parallel pipeline Priority: Minor Reporter: Yoram Michaeli When using a parallel step for an indexed loop, using the loop-iterator-index for internal usage results with wrong value (showing the max-index-value for all iterations). A workaround for it is to set a local variable for saving the current iteration-index and use the local variable. The following pipeline demonstrates the problem (the issue is demonstrated with the internal 'echo' steps): // code placeholder pipeline { agent any stages { stage('Explore bug') { steps { script { int maxIndex1=3 def loopers1 = [:] for (int loopIndex1 = 0; loopIndex1 < maxIndex1; loopIndex1++) { echo "loopIndex1=${loopIndex1}" loopers1["loop-$\{loopIndex1}"] = { echo "loopIndex1=${loopIndex1}" } } parallel loopers1 } } } stage('Bug workaround') { steps { script { int maxIndex2=3 def loopers2 = [:] for (int loopIndex2 = 0; loopIndex2 < maxIndex2; loopIndex2++) { int index2=loopIndex2 echo "index2=${index2}" loopers2["loop-$\{index2}"] = { echo "index2=${index2}" } } parallel loopers2 } } } } } Add Comment   This message was sent by Atlassian JIRA (v7.3.0#73011-sha1:3c73d0e) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
