I'm currently seeing the warnings below when trying to run my Google App Engine/Grails test app in Eclipse.

1. Warning, target causing name overwriting of name startLogging
2. Warning: C:\Users\Some Person.grails\1.2.0\projects\test-grails\plugins\app-engine-0.8.8\grails-app\conf\spring not found.
3. Warning: C:\Users\Some Person.grails\1.2.0\projects\test-grails\plugins\app-engine-0.8.8\grails-app\conf not found.
4. Warning: C:\Users\Some Person.grails\1.2.0\projects\test-grails\plugins\app-engine-0.8.8\grails-app\conf\hibernate not found.

Here is the output from the console:

I get this error after creating a Grails project with Spring Tools Suite (STS) and then installing the app-engine plugin "grails install-plugin app-engine". Before, I install the app-engine plugin the Grails project runs correctly.

Any ideas how to resolve these warnings?
