Based on the log output below this looks like
http://jira.codehaus.org/browse/MNG-5346
ie. the descriptor goal is running before the classes are compiled, and the
Java5 annotation extractor works off the classes.
You’ll need to update your plugin configuration to look like the example in
this link:
http://maven.apache.org/plugin-tools/maven-plugin-plugin/examples/using-annotations.html
ie. add additional executions to run the descriptor goal after the classes have
been compiled.
