问题
Back in December I switched from Eclipse to IntelliJ IDEA but within a couple of days I switched back. Today I tried IntelliJ again and basically I have only one issue left.
The issue is I want to compile Java classes on saving. The reason is I'm using JRebel which will pick up the new class. I don't want to hit ⌘+F9 every time to compile the changed class.
I read about the EclipseModel plugin but this does not seem to work (anymore) as can be read in the comments on the plugin's page: http://plugins.jetbrains.com/plugin/?id=3822
I also tried the "Make project automatically" but this compiles ALL classes and not only the changed class. This is only not more time consuming it will also cause JRebel to reload all classes.
Any suggestions?
回答1:
I ended up creating a Macro which does the Save and the Make Build. I then assigned the Ctrl+S shortcut to this Macro and then it works fine.
回答2:
What if you just remap the keys from Ctrl+F9 to Ctrl+S? Basically you will just keep up with the habit of pressing Ctrl+S since you do that in Eclipse - just a matter of pressing a different key in IntelliJ.
IntelliJ IDEA 12 indeed comes with out-of-process compiler which compiles the project classes automatically, but it seems to be unpredictable - you might refresh the page and the class is not yet compiled. So in the scenario with JRebel the off-process compilation is no use, unfortunately.

This may not be exactly what you want but normally I leave auto-save on, and when I need to compile the current class I'm working on, I just do Ctrl + Shift + F9.
回答4:
My IntelliJ IDEA version is 2017.3.4, and I modified some values so that it compiles automatically.
