The
junitplugin displays stdout & stderr separately, following the separated streams in SurefireTEST-*.xml. This is just confusing when you are trying to see the sequence of events: you need to mentally collate by timestamp to reconstruct the log you would see frommvn test -Dtest=…output (compare https://github.com/jenkinsci/plugin-pom/blob/8561e2e8c77c344d0465ec6c77e2e3eedc927c00/pom.xml#L1070-L1080) particularly if the output includes a mixture ofLoggerlines from the Surefire JVM and the Jenkins JVM.
