Answer 1

It seems the problem occurs if the groovy dependency of your grails is different than the groovy version installed on your local. I could reproduce the same issue when I tried to call grails war for a grails version dependent to Groovy 1.5 with Groovy 1.6 already installed. (BTW, Grails-1.0-RC3 is dependent to Groovy 1.5.0 and CallSite is introduced in Groovy-1.6.) When you call grails war , grails compiles its scripts by a wrong groovy version and fills the script cache.

To resolve this kind of issues, what I did is:

1. Removed all the files in ~/.grails/YOUR_GRAILS_VERSION/scriptCache/ folder.
2. Remove Groovy bin from path or use the correct groovy version in your local

Whenever you called, Grails will compile the scripts with the correct groovy version. I hope that helps.
