JRebel less useful in IntelliJ than Eclipse?

I just set up JRebel to use with my Spring web app in IntelliJ, and was very surprised to learn that I have to manually rebuild the project/recompile every time I want my changes to be reflected. Doesn't this defeat the whole purpose of JRebel? Is there something I'm missing here? With Eclipse it was nearly instant, make changes anywhere, save, instantly reflected in running app. With IntelliJ the process seems very clunky. Am I missing something here?

Running with JRebel in IntelliJ involves starting your application using Run > Run with JRebel and when you change your application code you have to build the project in order for IntelliJ to compile classes and update your application.

You can do this by running SHIFT + F9 or Build > Build Project

From the JRebel docs:

JRebel relies upon your IDE to do the compiling. JRebel reloads your compiled .class files and not your .java files. When you change code, JRebel pushes the changed classes and resources to the server without redeploying.

Regardless of what IDE you use, JRebel still needs the IDE to compile the classes before it can update the running application. IntelliJ is no different to Eclipse in this regard. Perhaps Eclipse was just auto building the project without you being aware of it. You can also instruct IntelliJ to auto build from Preferences > Build, Execution, Deployment > Compiler > Build project automatically.

Here's a screenshot showing that configuration setting:
