The zip file for 2.1.1 is from the grails site and i have yet to find anything missing. All grails commands are doing this.
Am i missing something?

Answer 1

Are you following asgard reccomandation??
Run Sun/Oracle Java 6 on Linux or Mac
Avoid Java 7
Avoid OpenJDK
Avoid Windows
Yes, Asgard runs on Grails, and Grails runs on Java, and Java is supposed to be "run
anywhere", except for the fact that Asgard users have reported incompatibility problems with
Java 7, OpenJDK, and Windows. A future version of Asgard will be Java 7 compatible, and
perhaps it will work with OpenJDK eventually. The Windows issue is less likely to get
debugged by Netflix engineers, but if you figure it out feel free to send a pull request.
