'make' is slow when restarting a test

Hi there

When I start a unit test and I restart it with Shift+F10 IntelliJ shows a quite long time the message 'make' at the bottom. Since I made no changes I thought it must be incredibly fast.

A colleague of mine tested that in eclipse and there the restart of that test starts immediately. I just wonder why this happens? What does IntelliJ more than Eclipse at this point?

Thanks in advance for clearifying
