Error when compiling GWT 2.4

[zeroconf]

Hello,

I'm trying to compile GWT 2.4 (http://google-web-
toolkit.googlecode.com/svn/releases/2.4). I followed the instructions
from http://code.google.com/webtoolkit/makinggwtbetter.html but this
failed with following error messages:

What did I do wrong?

Thanks in advance!

Actually, nothing. The requestfactory-apt.jar from GWT_TOOLS is not compatible with the releases/2.4 branch. Try setting "-proc:none" in your JAVA_OPTS to bypass the annotation processors (both RfValidator –which generates the error here– and RfApt, which shouldn't be an issue if skipped), or "-processor org.google.web.bindery.requestfactory.apt.RfApt" to only bypass the RfValidator (and any other that would have run, but there shouldn't be any), or simply revert your GWT_TOOLS to r10417.

See http://code.google.com/p/google-web-toolkit/source/detail?r=10417 (the changes applied in trunk, not in releases/2.4.0; not how FindRequest has been modified, whcih is the one failing the build in releases/2.4.0) and http://code.google.com/p/google-web-toolkit/source/detail?r=10418 (the updated requestfactory-apt.jar rebuilt with these changes)

This worked. Thanks a lot.
