Hi Rupert, I'm sorry to hear about your frustrations with Grails. I wonder if you can help us track down your issues.

This is just another example of a bunch of problems. grails says “I cannot do that… because… nightly build shot blah blah please use other version or run grails upgrade”.

This is the first I've heard of this issue. If you can describe your environment and the steps needed to reproduce this issue, we'd like to help. The Grails JIRA site is open for anyone to log issues. In fact, we encourage it.

Grails is changing too much all the time, it seems to be impossible to “start”. I mean - I do not want to start with grails 0.5.6 because 0.6 seems so much more sophisticated and 0.5 will soon cease to exist.

Such is the face of technology, but the Grails roadmap is clear in its intention to continue to grow the framework. Like most projects, you can expect to see a fair amount of change (albeit all in the name of progress) on the road to 1.0. Of course, once we reach 1.0 later this year, future changes will have a greater consciousness toward backward compatibility with older versions.

I would surely be willing to buy a book, if need be. Why not. But I fear a book will not help me either, because a book that is several months old (or at even a few weeks only) will most certainly refer to an outdated grails version.

Books aren't for everyone, but luckily there are many other sources to help you learn about Grails.

I do hope you'll help us track down your issue and give Grails another shot.

So I ran grails upgrade.

I am getting a 503 error.
