Answer 1

While my colleague and I have still have not discovered the reason this is happening (the Release 1.0.1 and SVN 1.0.2 plugins are being pulled into this app despite no reference in any of the in-house plugins or app itself's application.properties or BuildConfig.groovy), we have discovered a make-shift solution.

In the failing app's BuildConfig.groovy, if you specify

build ":release:2.2.1"

as a dependency, and you run

grails uninstall-plugin svn

on your command line, you should be able to stay on Grails 2.1.0 and keep this compilation error from occuring.

I will update my answer here if I'm ever able to find out why the old release plugin was being pulled in as a dependency ( I had bombed my ~/.grails folder as well as my ~/.ivy2, so I really have no idea why it was being pulled in ).
