FileNotFoundException for Config.groovy on GGTS 3.1.0 in Fedora 17

hi all,

I'm having an issue using GGTS 3.1.0 in Fedora getting a FileNotFoundException for Config.groovy, and was hoping someone here might have some advice.

I'm on 64 bit Fedora 17, using Sun jdk 1.7 u9, JAVA_HOME set, 64 bit GGTS 3.1.0 Release installed under my home directory. I've imported a grails project into my workspace dir, it uses grails 1.3.7 which is also installed under my home directory, and groovy compiler 1.7. I can compile the project using "grails compile" from the command line without errors, but in GGTS I get a few "groovy:unable to resolve class" errors, with the following error from the console where I start GGTS:
java.io.FileNotFoundException: ./grails-app/conf/Config.groovy (No such file or directory)
grails-app/conf/Config.groovy does exist, from the project root directory, and is readable.

This seems similar to STS-1636, but I tried the 4 step solution outlined there by Kris without success. I've also tried cleaning the project, refreshing grails dependencies, building outside GGTS and refreshing without success. I have 64 bit GGTS 3.1.0 Release installed on Windows 7 64-bit and can import the same project there without errors, but would prefer to develop from linux, preferably Fedora.

Does anyone have any suggestions how to fix this issue?

thanks,
apm
