Re: [Jung-support] compile error

[Danyel F. <da...@gm...>]

You can safely remove scratch.* ; those are test classes, code we're
trying to work out, dead ends, and similar.

If you are building a jar, you can also remove samples.* and test.* ;
those are (respectively) samplse of how to use JUNG and test classes
designed for JUNIT.

As for the corejava references, please make sure you've got the latest
version of COLT. (See the download page for the link to download it).
