Description

Added these jars to M2_HOME/custom to allow using scm based remote repos

bin/m2.conf

main is org.apache.maven.cli.MavenCli from plexus.core.maven

set maven.home default ${user.home}/m2

[plexus.core]
load ${maven.home}/core/*.jar

[plexus.core.maven]
load ${maven.home}/custom/*.jar
load ${maven.home}/lib/*.jar

When running "mvn install" and "mvn testwagonscm:test" in the attached test case you get a ClassCastException although the Class to assign to and the assigned one are the same. The problem seems to be that they come from different classloaders. This problem makes the project-info-report:scm goal fail.
