Jenkins pipeline plugin how to run parallel tasks
jenkins, jenkins-pipeline
Solution
I have the same problem. Perhaps I found the depending plugin: https://wiki.jenkins-ci.org/display/JENKINS/Pipeline+Supporting+APIs+Plugin See Release Note for Version 2.10 Regression in log handling with certain steps inside parallel in 2.9.
Yes updating the PlugIn works!
Problem
Jenkins pipeline plugin how to run parallel tasks I am a beginner in jenkins, I want to launch few tasks in parallel on available slave nodes of jenkins using pipeline plugin. I installed pipeline plugin and added below in the pipeline inline script section. ``` grovvy script : parallel firstBranch: { node('master'){ echo 'firstBranch' } }, secondBranch: { node('slave1'){ echo 'secondBranch' } } ``` NOTE: master and slave1 are my nodes What are firstBranch and secondBranch ideally ???? Console output: Started by user anonymous [Pipeline] parallel [Pipeline] [firstBranch] { (Branch: firstBranch) [Pipeline] [secondBranch] { (Branch: secondBranch) [Pipeline] [firstBranch] node [firstBranch] Running on master in /scratch/gnithyan/.hudson/workspace/pipeline_test [Pipeline] [secondBranch] node [Pipeline] [secondBranch] // node [Pipeline] [secondBranch] } [secondBranch] Failed in branch secondBranch [Pipeline] [firstBranch] { [Pipeline] [firstBranch] echo [firstBranch] firstBranch [Pipeline] [firstBranch] } [Pipeline] [firstBranch] // node [Pipeline] [firstBranch] } [Pipeline] // parallel [Pipeline] End of Pipeline java.lang.IllegalStateException: cannot start writing logs to a finished node org.jenkinsci.plugins.workflow.cps.nodes.StepStartNode[id=8] at org.jenkinsci.plugins.workflow.support.actions.LogActionImpl.(LogActionImpl.java:110) at org.jenkinsci.plugins.workflow.support.actions.LogActionImpl.stream(LogActionImpl.java:81) at org.jenkinsci.plugins.workflow.support.DefaultStepContext.get(DefaultStepContext.java:73) at org.jenkinsci.plugins.workflow.steps.StepDescriptor.checkContextAvailability(StepDescriptor.java:252) at org.jenkinsci.plugins.workflow.cps.DSL.invokeStep(DSL.java:179) at org.jenkinsci.plugins.workflow.cps.DSL.invokeMethod(DSL.java:126) at org.jenkinsci.plugins.workflow.cps.CpsScript.invokeMethod(CpsScript.java:108) at groovy.lang.GroovyObject$invokeMethod$0.call(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
