This is a problem. You're probably going to have other issues with
RestfulX/Sprouts integration too - since they also expose compiler
tasks and other sugar that Sprouts tries to take over.
To speak to this particular issue, Rubigen is what we (and Rails, and
Restfulx) use to generate classes, projects and other files.
Unfortunately, the latest version of Rubigen took a dump for some
reason along the way, so instead of figuring out why, I just updated
the Sprout gem dependency to a specific and old version of the Rubigen
gem.
There are only a handful of options that I'm aware of:
a) Try to change the dependency in the Sprout gem, increment the
revision, repackage and see if you can still generate projects,
classes, test cases, test suites, etc. Send me a pull request if this
works!
b) Do the same to your gem or sources of RestfulX, but specify the
older version instead.
c) Are you actually using RestfulX for anything other than the
library? If not, try to pull any references to them out of your
rakefile and instead just manually add their lib to your sourcepath.
Thanks,
