java - Debugging in IntelliJ (Reloading changed classes)

Question

I recently switched from eclipse to IntelliJ. Eclipse's debug launcher used to reload the application instantly, whenever a class was saved. IntelliJ takes more than 10 secs to reload changed classes, which might not be a lot, but it is annoying because I use it so frequently.

How to make IntelliJ reload changed classes faster?

Answer 1

To reload changed classes

1. Do one of the following:

• On the main menu, choose Run | Debugging Actions | Reload Changed Classes.
• On the main menu, choose Build | Compile "class_name" to recompile an altered class during debug.

2. In the Reload Changed Classes dialog box, confirm reloading. Results are displayed in the Messages tool window.
