Did you download the source from the distribution or from the svn repo? You may want to try this from the repo, it may help with some.
There are going to be some compilation errors anyway because of some of the generated source files that the CDK creates. Most of us use eclipse, but has some similar items. There are also some non-support file types and extensions ( addressed in 4.0 ). However the issue you stated above is new to me.
PS: I'm going to move this to the user forum
I downloaded from the distribution (3.3.3.final). I opened the project from the pom in NetBeans. I looked at the dependency jars and it looks like its referencing jsf2.0 libraries and that would be a bit of a problem for compilation wouldn't it? If I'm using jdk1.5 in the build?
Is there any build/configuration document available that outlines what versions of java and/or other libraries the build is compatible with?
