Compiling source using Eclipse 3.2 + Maven 2

Hi!
I have a problem compiling subsonic 3.2 with Eclipse 3.2 and Maven2.
I've downloaded the sources, let Maven download the needed files and added some files manually when Maven wasn't able to download them (jdic and jgoodies looks/forms).
Now I want to build/compile/package the project but this doesn't work.
I think it's because the subsonic author is using IDEA as IDE and not Eclipse.
There is a special "maven-idea-plugin" section in the main pom.xml file.
Who has a solution?
EDIT: I think I got it. It works when I run it from the commandline... mvn compiler:compile
Background why I want to compile the source again:
I want to backport Subsonic to an older Java Version (1.4). I have a target platform where no Java 1.5 or greater is available.
Thanks!
