Subject Re: AW: Passing a list of files to javac
Date Thu, 11 Mar 2010 10:42:15 GMT
That solves the minor problem of ; vs , but doesn't solve the real problem. The real problem
is in getting javac to recognize a filelist/fileset/path. What I'm looking for is something
to replace the filelist that javac will accept.
