Sorry guys, my analysis was premature. I figured out the issue (which
likely applies to java5 annotations on java mojos as well as groovy).
By default, the maven-plugin-plugin:descriptor mojo runs in the
generate-resources phase. But of course, the class files (from compile
phase) with the java-annotations are not there yet. So all I have to do is
add:
<executions>
<execution>
<id>default-descriptor</id>
<phase>process-classes</phase>
</execution>
</executions>
to my maven-plugin-plugin declaration and it works even with mvn clean
install.
Perhaps this should be updated on
http://maven.apache.org/plugin-tools/maven-plugin-plugin/examples/using-annotations.html
As well, the mvnref book is out of date:
http://www.sonatype.com/books/mvnref-book/reference/writing-plugins-sect-custom-plugin.html
which
says Maven does not support java5 annotations.
My misguided analysis before was caused by mvn install working but mvn
clean install not (when eclipse generated the class files prior to the
build).
Thanks,
Ben
