hbm - Duplicate Class Entity Mapping - Why!?
Please help. This is driving me crazy at this point.
I have a very simple class and corresponding hbm.xml file. I had it working this morning perfectly. I added a second hbm.xml file to the mix and everything stopped working. I removed the second hbm.xml and reverted back to the original and it now gives me a "Duplicate Class Entity/Mapping" message on the original hbm.xml.
I'm using spring-security-core and spring-security-cas plugins although they seem to have been causing no issues. I am letting GORM handle the Role and User_Role entities and am using hbm for the User because I need to pull data from my legacy DB during authentication.
I happened to look at my plugins directory and see a 'release 1.0.0.M2' entry that I did not install and is are not a part of any of my other projects. I can uninstall it but when I do a run-app it is redownloaded and installed.
I ran clean and then a refresh Grails Dependencies but it did not help.
I am running STS 2.7.1 RELEASE Build 201107091000. (The current Mac OSX dmg downloads that are out there on the STS download page appear to be corrupted). I mention this because I have been getting random 'Cannot resolve class E' error messages in the STS IDE ever since I download and installed STS tar.gz last week springsource-tool-suite-2.7.1.RELEASE-e3.7-macosx-carbon.tar.gz (I tried both the cocoa and carbon dmgs with no success, it opens disk utility instead of installing the app). My old STS install would have an eclipse-groovy update everyday and this one has none. I am wondering if there is an issue with the IDE itself.
