How to enable Intellij hot code swap

Question

Intellij does not seem to be doing basic hot code swap on my installation.

For this code:

public class MainTest {
    public void method1() {
                


        

Answer 1

I wanted hotswap to automatically run every time I saved a Java file. None of the other answers did this so I just:

1. Created a macro that will run on save: https://stackoverflow.com/a/5581992/14731
2. Added Action: Hotswap at the end of the macro (Run -> Reload Changed Classes)
