Hi, I'm getting this error when I tried to switch from version 1.5 to version 1.5.1.
(Note that the optional.jar in ANT's lib dir is the one shipped with ant v1.5.1, i did not try to reuse the old one) Invalid implementation version between Ant core and Ant optional tasks. core : 1.5.1 optional : 1.5 I noticed that in the rpms, you can theoretically get the optional.jar seperately, but not in the bin release Thanks, Chuck
