What patches have been made to Maven before this error appears? When you
say "heavily customized" are you talking about patches that change the
way Maven handles POM metadata, things like that?
I'm not sure I've ever seen it in an unaltered version of Maven.

Hi,
During the maven 2.2.x update for Fedora I've met a problem:
org.apache.maven.lifecycle.LifecycleExecutionException: Internal error
in the plugin manager getting plugin
'org.apache.maven.plugins:maven-enforcer-plugin': Plugin
'org.apache.maven.plugins:maven-enforcer-plugin' has an invalid descriptor:
1) Plugin's descriptor contains the wrong group ID: org.codehaus.plexus
2) Plugin's descriptor contains the wrong artifact ID: plexus-maven-plugin
3) Plugin's descriptor contains the wrong group ID: org.codehaus.plexus
4) Plugin's descriptor contains the wrong artifact ID: plexus-maven-plugin
To analyze this problem more carefully, I'v added some log in
'maven-core/src/main/java/org/apache/maven/plugin/MavenPluginCollector.java' :
...
if ( !pluginsInProcess.contains( key ) )
{
line61: pluginsInProcess.add( key );
added log: System.out.println("*DEBUG*: Putting in plugin descriptor list
" + key + " and goal prefix is " + pluginDescriptor.getGoalPrefix());
pluginDescriptors.put( key, pluginDescriptor );
...
And then I get:
*DEBUG*: Putting in plugin descriptor list
org.apache.maven.plugins:maven-enforcer-plugin and goal prefix is enforcer
*DEBUG*: Putting in plugin descriptor list
org.apache.maven.plugins:maven-enforcer-plugin and goal prefix is enforcer
*DEBUG*: Putting in plugin descriptor list
org.codehaus.plexus:plexus-maven-plugin and goal prefix is plexus
*DEBUG*: Putting in plugin descriptor list
org.codehaus.plexus:plexus-maven-plugin and goal prefix is plexus
The above output is strange to me: seems when maven-enforcer-plugin invoked,
it's overwritten by org.codehaus.plexus:plexus-maven-plugin.
Because in Fedora the maven is heavily customized and its called 'mvn-jpp', and
I'm not quite familiar with the internal scheme of maven. Can anyone gives me
some clue about where to find the above problem? In which situation will
multiple plugins collected by MavenPluginCollector.java?
Here's the detail log:

Thanks for any help!
