17.5.5 Reloading with an IDE

If you are using a build tool such as Maven, which does not support automatic recompilation on file changes, you may choose to use your IDE to recompile classes in combination with a reloading agent (as configured in the above sections).

IntelliJ

IntelliJ unfortunately does not have an automatic rebuild option that works for a running application. However, you can trigger a “rebuild” of the project with CMD-F9 (Mac) or CTRL-F9 (Windows).

Eclipse

Under the Project menu, check the Build Automatically option. This will trigger a recompilation of the project whenever file changes are saved to disk.
