Olivier, If the project you are pointing is what is behind "Maven Integration" in Jenkins then it does things wrong by not taking into account maven core-extensions.
I just retested now: - download Jenkins.war 2.232 - launch as java -jar - default installation - add plugin "Maven integration" - in settings add a local JDK 11 - in settings add a default maven 3.6.3 - create new job "jgitver in jenkins" - set git url : https://github.com/jgitver/jgitver.git - set goal : validate - run the job You will see in the output that the version of the project is 0 whereas it should have been computed by a core extension. ... [INFO] ---------------------< fr.brouillard.oss:jgitver >---------------------- [INFO] Building GIT versioning using jgit 0 [INFO] --------------------------------[ jar ]--------------------------------- ... If you do the same in CMD/sh you should see the automatic computation [INFO] Using jgitver configuration file: C:\workspace\projects\oss\jgitver\jgitver-lib\.mvn\jgitver.config.xml [INFO] Using jgitver-maven-plugin [1.5.1] (sha1: e45d1669b39cedb98720dd33cc14d0185b455ca1) [INFO] version '0.12.1-SNAPSHOT' computed in 15595 ms [INFO] [INFO] Scanning for projects... [INFO] jgitver-maven-plugin is about to change project(s) version(s) [INFO] fr.brouillard.oss::jgitver::0 -> 0.12.1-SNAPSHOT [INFO] [INFO] ---------------------< fr.brouillard.oss:jgitver >---------------------- [INFO] Building GIT versioning using jgit 0.12.1-SNAPSHOT [INFO] --------------------------------[ jar ]--------------------------------- ... This is not particular to jgitver but to any core extension (takari polyglot, tycho pom less, ...). The way this jenkins project loads the Maven Project Object Model is somehow wrong or at least not complete. IMO the POM loading is better done in maven-flatten-plugin.
