Java 5 compliance level or above

I'm pretty new to Roo and STS.

I'm using Java 1.7
STS Version: 3.1.0.RELEASE Build Id: 201210061306.

After creation of a ne Roo project I always need to create the folder src/test/resources manually. Is there a way to let the system create that folder automatically?

Then I create sone entities and after the command: "web mvc setup" there are several hunderds of problems. Most of them are:

"declare @type is only supported at Java 5 compliance level or above" but I'm using Java 1.7 !

After changing everything to Java 1.6 right from the beginning I do not get the second problem any more.
