Quick export in IntelliJ (File in use)

Previously, to recompile my plugin, all I had to do was generate the jar again using a .jardesc in Eclipse, then doing a /reload.

This was incredibly convenient and worked wonders while developing.
Eclipse would overwrite the file succesfully.

When I moved to Intellij, I realized that it didn't like the fact that the file was in use when building the artifact.

Is there any way I could get around this?

EDIT WITH SOLUTION:

It's just a warning, it cannot delete the file, however it writes successfully.
Just hit ignore warnings on the compile log if you don't want it to pop up.

 

Stop your server, compile (on your server path) while "Loading libraries" with a cycle .bat (or .<similar batch file from windows but for linux that I don't remember>).

Please don't /reload, you know that this is bad );
