Hi, it seems in 3.1.x, since Aether was swapped from Sonatype one to Eclipse one, the filtering was not updated, and Eclipse Aether is getting into plugin Class Realms...
See https://github.com/apache/maven/blob/892b464683645bcdc1d28febf0bf3cc1c3181350/maven-core/src/main/java/org/apache/maven/DefaultArtifactFilterManager.java#L83 I just hit this problem, see aether-users list [1] Created issue [2] [1] http://dev.eclipse.org/mhonarc/lists/aether-users/msg00251.html [2[ http://jira.codehaus.org/browse/MNG-5513 Thanks, ~t~
