For example, with netbeans 6.9.1:
libs.CopyLibs.classpath=/opt/netbeans-6.9.1/java/ant/extra/org-netbeans-modules-java-j2seproject-copylibstask.jar
libs.CopyLibs.javadoc=
libs.CopyLibs.maven-pom=
libs.CopyLibs.src=

Thanks, and I’ll come back later to read about the root cause.

I’ve changed it as you suggest and all is back.
Thanks

Anyway, this issue came back on 6.7RC1.
…interesting, ain´t?

I have my IDE (nb). I have my java. It compiles, runs like a charm. But it is absolutely riddled with nasty version issues such as the above, ant snafus like “else” statements in 1.6.5 that break 1.6.1, annotations in Junit you name it.

So when I try to check in my code with everyone else’s the thing b0rk5 big time. What a tedious business. I have actually gond back to HAND CODING my java in Emacs and using Makefiles, javac and jar because that way everyone knows what going on.

I am severely annoyed with this. Not content with layer upon layer of complex, superfluous XML, config and all the other bollox that utterly removes any vestiges of usefulness from J2EE – I now find even the most basic tasks on Netbeans have become fundamentally unusable to.

Its embarrassing. Ive got Python wankers LAUGHING at me here because between my wonderful OS and my wonderful programming language the propellorheads have inserted so many dependencies and magic happenings that any java development is now more or less impossible.

Thanks. But not thanks. Netbeans is gone.
