Does Intellij automatically update classes you've made changes to while in Debug mode?

I know that for css, html, and gsp files you can just refresh the browser without having to rebuild the application in order to see your updated changes. If you're stepping through code in debug mode, and make a change for a groovy or class file, do you have to rebuild the application in order to see the change?

Say you're stopped on a break point, and want to edit the source code of the method you're in. Make the edit, save it, then run > Reload Changed Classes. Then, in the debugger controls, Drop Frame. Without dropping the frame, you won't execute the your newly recompiled method body.

By default, there's no keybindings for these 2 commands, but you can create them via the KeyMap in the settings (ctrl + alt + s). Even better, you can make a macro that will execute both these commands for you.

I wish it was easier and automatic, like in eclipse, but oh well.

IntelliJ does not update the classes in your running application automatically. You need to compile them manually (this will not be a full project rebuild - IntelliJ will build the project incrementally and compile only the changed classes and the code that depends on them), and then IntelliJ will offer you to reload the changes (which may fail if the changes you made aren't supported by the Java hotswap).

Note that some Web frameworks may be able to reload the changed classes automatically, independently of whether you're running your code from IntelliJ or not.
