Cerberus + RVM (or, multiple Ruby installs)
Matthew Krom
Craig Jolicoeur
There is a basic ruby builder that you can use to build your project.
The ruby builder allows you to set an explicit path to your ruby
executable and then execute a ruby script. You also can include a
custom regexp to decide if the build was a success or failure since
your script will probably have custom output.
We have a user who builds Rails and a few other projects on 4 or 5
different versions of Ruby and this is the method he uses.
Take a look at the "builder options" section of
http://wiki.github.com/cpjolicoeur/cerberus/configuration
There is no need to have multiple versions of cerberus installed
though. You can use the same cerberus gem and just setup different
projects under cerberus for each version of Ruby you want to build off
of.

possible to specify a custom rake_path the same way you can specify a
custom ruby_path, it would solve this (rvm provides a rake wrapper for
each installed ruby version).
In the meantime, I was able to get something working by based on
Craig's suggestion of using the ruby builder and by passing rvm as the
"task". In case it's helpful to anyone, the builder portion of the
project config looks something like this:
builder:
ruby:
task: ~/.rvm/bin/rvm 1.8.7 rake some-rake-task
I setup a separate Cerberus project for each version of ruby in order
to track the status of each separately, but a single "cerberus
buildall" will build each with the appropriate ruby version as
configured.
