FYI I have... 79 specs failing on Windows 7 + java 1.6.0_18-b07 + jruby 1.4.0 + buildr r918501 13 specs failing on ubuntu 9.10 + java 1.6.0_15-b03 + jruby 1.4.0 + buildr r918501
...and one of the differences is Buildr::ZipTask 'should create new archive when updating' (fails on Windows). If I can be of any more help testing or verifying things on Windows, let me know. -- Will
