I tried the suggested command with the current version:
mvn org.apache.maven.plugins:maven-compiler-plugin:2.3.1:help
-Ddetail -Dgoal=compile
and things are fine (as I was searching for).
However for the old version I was searching for (2.0.2) it doesn't
work..such auto-documentation was not implemented for that version..?
mvn org.apache.maven.plugins:maven-compiler-plugin:2.0.2:help
-Ddetail -Dgoal=compile
