When running buildr from ubuntu 11.04 I had to explicitly write build

When running from ubuntu 11.04 with jruby 1.5.1 (ruby 1.8.7 patchlevel 249) , in order for the classes to be built, I had to explicitly define the build parameter while running it on windows didn't require it.

The command was

buildr clean build package test:Suite junit:report test=all--trace

(see the build parameter which according to the documentation should be run by default).
