Yesterday downloaded IDEA Irida EAP B#3075, imported a (J2EE) project from 4.5.
First, the JBoss plugin from Fuhrer failed... ok, I expected this and removed it (deploying to JSAS anyhow), remoed JBoss DDs and restarted.
Still, J2EE features didn't work, Irida didn't recognize DDs (ejb-jar, application etc.), strange enough, some XML-entities/elements were recognized, some not (???); also, building an EJB module doesn't seem to work when a dependent-upon module is set to "JAR, link via manifest" (fails with "Library.jar is a directory"), "copy to /" works; the module's directory is filled with "crap" (the various library-jars, a "Library.jar" directory (probably from my module "Library", but contains all classes) and the EJB-jar file seems to contain ALL classes of the project (?).
Just a first experience, regards,
