Let me know if you'd like me to release this for you. I'd leave you as the author, but this seems like a pretty useful plugin.
removed unused error.gsp and exclusion for it
deleted jars that grails already provides
deleted unused files
plugin.xml shouldn't be in source control
STS project files
removed jars and replaced with dependencies
replaced html license with text license so the release plugin doesn't…
upgrade to 2.0 for development and switch to release plugin to create…
… releases that work correctly with 2.0 apps
removed use of deprecated ConfigurationHolder
changed min version of Grails to 1.3
renamed to ajax-proxy since proxy is too generic
Thanks for the cleanup. Sure go ahead and release the plugin -- that would be awesome!
