Maybe you miss a reply: I tried also with help:describe but, with this command, not all parameters have an associated description of default value (although it exists because I remember that the old site documentation says that the default value for source is 1.4, for version 2.0.2 of the compiler plugin).
The command I wrote was: mvn help:describe -DgroupId=org.apache.maven.plugins -DartifactId=maven-compiler-plugin -Dversion=2.0.2 -Dcmd=compiler:compile -Ddetail did I miss something? 2010/8/3 Anders Hammar <and...@hammar.net>: > As I describe in my blog post, the help mojo doesn't always exist.
