问题
When I used previous versions of Eclipse (e.g. Ganymede/Europa) if I had edited a file and then attempted a build Eclipse would prompt me to save first.
Since I updated to Galileo (Build id: 20090920-1017 & just checked for updates) when I build I'm not prompted to save first. Perhaps the dialog had a checkbox for "don't tell me again" which I mistakenly checked on???
I figure it is just a preference setting some where but I can't seem to find it, search in Preferences for 'save' and for 'build' but did not find it. I tried "Save automatically before build" but that actually did not work for me, and isn't really what I was looking for anyways.
Any ideas?
thanks.
Edit: I'm actually using an Ant script to 'build' (right click on script and Run As...Ant Build). So perhaps my original wording was a bit off base since I did not state how I was building.
回答1:
It's under Window -> Preferences -> General -> Workspace -> Save automatically before build. This works for me if I'm doing an Eclipse build (Project -> Build All). Is that how you're building?
回答2:
As mention in this thread, the only other options (other than the "Save automatically before build") which actually prompt for the user for file saving are:
> Run/Debug > Launching > Save required dirty editors before launching
> Run/Debug > Launching > [x] Build (if required) before launching

Answer of VonC looks great, but does not work as it seems (Eclipse 3.5.1.R35x_v20090910 on WinXP-Pro-32). However Eclipse and I seem to think differently about what is a "required dirty editor" :-( --
Would be nice if it would be possible to define a scope of resources to check for dirtyness for every single launch configuration -- with "containing project & refernced projects" as the default setting.
But it looks like 3.5.2 fixes this problem.
