After the post on dev@, I received some consents and some hints.
So I must add this features:
1) a better and more explicit dependencies selection;
2) add some properties from build.properties (like samples, javadoc, sources in jars, etc);
3) call ant task for build the project;
4) start/stop of jetty;
5) better UI’s look&feel;
For the point number 5 I’m searching for a volunteer, anyone?
