Now it's working!!!!! \o/
Ive downloaded the alpha4(tried SNAPSHOT, Betas 2 and 3 without success)
release and just changed the FORGE_HOME to point to it and solved the
injection problem.
I also had to add
<dependency>
<groupId>org.jboss.shrinkwrap.descriptors</groupId>
<artifactId>shrinkwrap-descriptors-api</artifactId>
<version>0.1.7</version>
</dependency>
in order to use forge-shell-api 1.0.0-SNAPSHOT.
And finaly added commons-lang-2.4.jar, commons-collections-3.1 to
forge_home/lib
and now i can see "Wrote
/JAVA/Projetos/Conventions/Conventions/ConventionsLayers/src/main/java/com/jsf/conventions/layers/controller/Per
nMBean.java" after my command execution
many thanks for your help, keep the great work!
