Description

Actual:

$ mvn -f .../mojo-archetypes/ear-javaee6/src/main/resources/archetype-resources/pom.xml versions:help
...
[ERROR]     Resolving expression: '${version}': Detected the following recursive expression cycle: [version] -> [Help 2]
[ERROR]     Resolving expression: '${artifactId}': Detected the following recursive expression cycle: [artifactId, version] -> [Help 2]

...

Expected:

...

[ERROR]     Resolving expression: '${artifactId}': Detected the following recursive expression cycle: [artifactId] -> [Help 2]
[ERROR]     Resolving expression: '${groupId}': Detected the following recursive expression cycle: [groupId] -> [Help 2]
...

PLXCOMP-159 is responsible (confirmed by substituting patched JAR). I am not positive but I believe this is also the cause of a critical (if sporadic) error in the NetBeans embedder, starting to appear I think when RC1 was integrated (maybe RC2): https://netbeans.org/bugzilla/show_bug.cgi?id=190530

PLXCOMP-158 is also related.

Please consider producing a new release of plexus-interpolation containing these two patches and using it in Maven 3.0 RC3.
