Yes, AFAIC it doesn't use maven.

The latest gwt plugin for eclipse (since 2.0.3) isn't hardcoded to the
/war directory, so the /war issues is not longer relevant normally.
See the note on
http://mojo.codehaus.org/gwt-maven-plugin/user-guide/war-folder.html
So don't use an old gwt plugin for eclipse.
Toni Rikkola is working fine with eclipse, maybe you can ask him how he
said it up?

There is the sources wierdness. Basically gwt needs the *.java sources
of all the java to javascript it needs to compile, not just the *.class
sources. So to be able to compile drools-guvnor it needs the sources of
drools-ide-common.
- If you have drools open in IntelliJ/Eclipse, this isn't a problem: the
sources are there anyway and you don't need to configure anything
special. Note you can't have just drools-guvnor open without
drools-ide-common open... I would expect this to be the same for netbeans
- In Maven, things are different because modules need to be able to
compile individually. There are 2 ways to handle it:
-- the GWT hack way: just add the sources to the jar. This is the bad
way as it violates the maven repository contract.
-- the maven way (which we follow): also install/deploy the sources into
the repository as a separate jar (so as a
drools-idea-common-...-sources.jar) and re-use that to build
drools-guvnor (and note that the maven intellij/eclipse reuse those
sources to automatically download sources etc).

idem dito :) Hope this helps too
