Building multiple matrix builds (of one job) at once results in the following exception from the p4 plugin. The job is configured as: Multi-configuration project Execute concurrent builds if necessary: true p4 scm with a Manual workspace: jenkins-$ {NODE_NAME}-${JOB_NAME} //depot/tool/... //jenkins-${NODE_NAME} -$ {JOB_NAME} /... User-defined Axis Name: "FOO" with Values "bar baz" And a single build step executing a Windows batch command: "ping -n 10 127.0.0.1 >nul" to sleep for 10 seconds. Trigger the same job at least twice in quick succession. The first succeeds but the subsequent ones get the above exception. It appears to be a problem when the matrix per-configuration build uses the same node as the flyweight job. This is reproducible with a system with 1 executor on master. {{Building on master in workspace C:\jenkins\jobs\matrix_p4_multiple_executions\ws@2\FOO\bar FATAL: 1 java.lang.ArrayIndexOutOfBoundsException: 1 at org.jenkinsci.plugins.p4.tasks.AbstractTask.setEnvironment(AbstractTask.java:108) at org.jenkinsci.plugins.p4.PerforceScm.checkout(PerforceScm.java:312) at hudson.scm.SCM.checkout(SCM.java:485) at hudson.model.AbstractProject.checkout(AbstractProject.java:1269) at hudson.model.AbstractBuild$AbstractBuildExecution.defaultCheckout(AbstractBuild.java:607) at jenkins.scm.SCMCheckoutStrategy.checkout(SCMCheckoutStrategy.java:86) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:529) at hudson.model.Run.execute(Run.java:1738) at hudson.matrix.MatrixRun.run(MatrixRun.java:146) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:410)}} |
