Yes, I'm aware of that. Via most IDEs, one can modify java classes and reload the changes without restarting the entire application. This simply does not work with groovy based classes. I'm using Resin, but I contacted them and they said it's a groovy problem. So I tried it in Tomcat and they were right, it doesn't work there either.
Maybe it's not supposed to work, but it's seems a major inconvenience if this is true.
I have some groovy classes in my application, All works well if compile and deploy the application.
My problem is isolated to the development process. If I make a change to any groovy based class, bean or otherwise, no matter what the change, and attempt to reload the classes via hotswap, the changes aren't reloaded. In Resin, the entire app restarts. In Tomcat, the app doesn't restart and the changes are not detected.
I have the groovy all jar in my classpath and that's it. I'm using intellij, but it is no doubt using groovyc to compile the groovy classes. But when not in the IDE and using Resin, which supports auto reloading of modified classes, I have the same problem with groovy classes. It can't reload them without restarting the application.
Basically, the hotswap feature supported in all java IDEs doesn't work on groovy classes. Or so it seems. Just want to know if there is some kind of work around and/or if this is a issue being addressed in future versions of groovy.
Posted here, and at least one other users seems to be aware of the problem.

It just doesnt reload automagically when Groovy source files have changed.
