Subject Re: ZipException on javac task moving from jdk1.4 to jdk1.5
Date Tue, 07 Jun 2005 21:48:07 GMT
This should be a FAQ!

You have a .class file in your class path (i.e. not a directory
or a .jar file). Starting with ant 1.6, ant will open the
files in the classpath checking for manifest entries. This attempted opening
will fail with the error ""

The problem does not exist with ant 1.5 as it does not try to
open the files. - so make sure that your classpath's do not
contain .class files.
