Typically you have your grails installed into some directory, created environment variable GRAILS_HOME and you are ready to go.

But what if you have few projects with different grails versions? You can have different reasons for that, but nevertheless you need it.

Here is short tip how this process can be simplified, example for linux (Ubuntu).

CODE:

/usr/local/grails-2.0.0
/usr/local/grails-2.1.1Lets create link to any version of grails

CODE:

ln-s/usr/local/grails-2.1.1 grails
