Nick Cross updated MNG-7160: ---------------------------- Affects Version/s: 3.6.2 > Extension And Classloaders > -------------------------- > > Key: MNG-7160 > URL: https://issues.apache.org/jira/browse/MNG-7160 > Project: Maven > Issue Type: Bug > Affects Versions: 3.6.2, 3.8.1 > Reporter: Nick Cross > Priority: Major > > I have a project that we use for all of our internal Red Hat builds (although > primarily through its CLI mode hence not noticing this until > [https://github.com/release-engineering/pom-manipulation-ext/issues/832] was > submitted in the community). This project creates an extension (lib/ext > style) but trying to use it as a ".mvn/extensions.xml" it _seems_ to get a > classloader problem as _I think _the Maven Model/Plugin objects are created > within a different classloader which means when the Plugin configuration is > retrieved and cast to a Xpp3Dom object it fails. Is there some configuration > we are missing or is there a problem in how the classloading in Maven for > core extensions is working when using Xpp3Dom ? > An reproducer branch is > [https://github.com/rnc/pom-manipulation-ext/tree/ISSUE832] > (Simply build and install the project, then use it on any simple Maven > project with an extensions.xml with the command e.g. "mvn -X >
