I have just installed grails 2.0.3 on my Ubuntu box using apt-get as described here:
Everything looked fine.
When I type grails in the terminal it takes about 5 seconds and then it returns to the prompt without having done anything. No errors, no text.
I have tried adding GRAILS_HOME even though the download instructions say it is not required but that didn't help either.
It's finding grails just fine, it's just not doing anything.
I have not explicitly installed groovy before this. Is that a step I missed (I don't think so as I see it's included in the libs folder of the install) or is there more I need to do to finish the install?
