Eclipse3.0 removes class files automatically

hi,

I've noticed that Eclipse removes all class files in the following cases:

1) Whenever I save a source file (and 'Build Automatically' is on) Eclpise runs 'Building workspace...' (you can see it on the lower right corner of eclpise), and this process actually removes all the class files.
So when I choose ant target to compile my java classes it compiles ALL the files although I saved only one file.

2) If I turn 'Build Automatically' to off, then Eclipse run the 'Building Workspace' only when I select an ant target to build the project. so Again, all the class files are removed just before I choose to compile them, so again, I'm compiling all the sources!!!

Anyone knows why it removes all the class files, and how to solve thsi problem? I can't have partial compilation now.

thanks,
Nira.

Well, the fix is to not use Ant to compile. Why would you want to, anyway? You are loosing all the benefits of the incremental Eclipse compiler...

How exactly I should use the eclipse compiler to compile incrementaly?

Should I check the 'Build automatically' on and use my ant file only for building the jar? or I should turn off the 'build Automatically' and use 'Build Project' once in a while? When I click on Build Project, it looks like nothing happens. Also Build All didn't compile my sources...

Any idea?

That's one option, especially if you are the only one working on the project.

In a team it might be a better idea to build distributions totally outside of Eclipse, on a build server or something.

When I click on Build Project, it looks like nothing happens. Also Build All didn't compile my sources...


Take a look at wether the Build Path is set correctly for your project...

well, yes, the Build path is set correct.

Any other idea?
