Description

rm -rf test && mvn -DarchetypeVersion=1.0 -DgroupId=test -DarchetypeArtifactId=osgi-archetype -Dversion=1.0-SNAPSHOT -DarchetypeGroupId=org.codehaus.mojo.archetypes -Dpackage=test -DartifactId=test -B org.apache.maven.plugins:maven-archetype-plugin:2.0-alpha-4:generate

succeeds. The same with 2.0-alpha-5 fails:

[ERROR] Cannot parse archetype descriptor
org.codehaus.plexus.util.xml.pull.XmlPullParserException: Unknown attribute 'id' for tag 'archetype-descriptor' (position: START_TAG seen ... id="osgi-archetype" partial="false" name="OSGI Bundle archetype">... @2:88) 
	at org.apache.maven.archetype.metadata.io.xpp3.ArchetypeDescriptorXpp3Reader.checkUnknownAttribute(ArchetypeDescriptorXpp3Reader.java:99)

Indeed the id attribute is not supposed to be there, and http://fisheye.codehaus.org/browse/mojo/trunk/mojo/mojo-archetypes/osgi-archetype/src/main/resources/META-INF/maven/archetype-metadata.xml?r2=12260&r1=11739 fixed this and will be in the next archetype release.

In the meantime, though, anyone trying to use the latest maven-archetype-plugin with the latest released archetype will be unable to, even though the unrecognized attribute did not actually harm anything. Please downgrade this class of error to a warning, at least for a while until corrected archetypes are broadly available.

Will try to create & submit a patch upon request.
