Jenkins LTS 1.532.1
Flexible publisher plugin 0.12
Jenkins Subversion Tagging Plugin 1.16
I have a matrix job with 2 labels and the flexible publisher as post build action.
I checked the check butten "Condition for matrix aggregation", set "Run on parent?" to "Always" and set "Perform subversion tagging on successful build" as action.
Result: The matrix parent job performs no tagging! The parent jobs console output even shows no output from the flexible publisher plugin.
Originally I hoped the new matrix support will solve this problem: https://issues.jenkins-ci.org/browse/JENKINS-9683
