Eclipse doesn't save files before running, debugging,

Normally Eclipse saves my unsaved files before starting to debug or run a a开发者_如何学Gont script. This isn't working anymore.

The general -> safe before build is ticked. I have cleaned the project and restarted Eclipse. What am I missing?

FailedDev pointed me to a thread talking about these kind of issue. Going under Window -> Preferences -> run/debug -> launch -> save dirty... did the trick.

Recently this was happening to me which I found really really annoying on my eclipse 3.8.1 running on Ubuntu 13.4. Below trick fixed it.

Window -> Preferences -> run/debug -> launching > check the optoin: Build (if required) before launching
