This is my default BuildConfig.groovy from now on

Took some time to fine tune it.
- prod war exports to appName.war without app version

- build and runtime features hsqldb version 2.2.4 instead of the 1.8 which is included with Grails and unusable since I need to use more sophisticated SQL commands like MERGE - just to make sure, the lib directory contains hsqldb-2.2.4.jar (and not hsqldb.jar - this is but a simple change of the file name).
