How to use git-built Roo in Eclispe/STS

amy

I was going to ask; but then I found it!
Here for anyone else looking:

I can successfully build roo from git source, and run it using the roo-dev script.

But how to set this roo into Eclipse?
Project-gtroperties-gt;Spring-gt;Roo Support-gt;Configure-gt;Add

Browse to directory containing quot;bundlequot;: .../roo/bootstrap/target/osgi

The 'trick' is that you must *first* run the roo-dev script to start roo from the cmdline.
Creating the target/osgi directory appears to be a side-effect.
