grails-maven-plugin issues
http://jira.grails.org/browse/MAVEN-86
- Fixed with commit 6e4e2ad, pull request 15
http://jira.grails.org/browse/MAVEN-118
- Can be closed? grails-webflow no longer exists as a dependency
http://jira.grails.org/browse/MAVEN-84
- Not an issue anymore? java.home is an exposed property from maven, and there are no more references to java.version
http://jira.grails.org/browse/MAVEN-68
