Huh! I just found out, there is a fine Maven2 Plugin for J2ME. It comes with an archetype to jump-start developing J2ME applications with maven.
Use the archetype like this:
$ mvn archetype:create -DarchetypeGroupId=com.pyx4me
-DarchetypeArtifactId=j2me-simple -DarchetypeVersion=2.0.3-SNAPSHOT
-DremoteRepositories=http://www.pyx4me.com/maven2 -DgroupId=org.example
-DartifactId=myapp
And if you develop against a nokia phone, it comes even better – there’s a gammu maven plugin, too!
