Yup, Project -> Clean did it for me, just as well too as the laptop was heading for the window. You’ve saved my sanity and my laptop repair bill.

Huge thanks

Comment by David Resnick worked for me too, thanks.

It seems all class files aren’t the same? If Ant compiles the .class file to the (shared) build path and it’s up-to-date Eclipse determines by default that the file shouldn’t be overridden.

The ”Rebuild class files modified by others” setting tells Eclipse that if it needs the class file rebuilt (in a different format? or does it include extra properties) to just do it – rather than reporting problems about the class not existing.

Note, in 3.5 you could also have this setting on the project itself: Right-click the Project ->Properties->”Java Compiler”->Building->”Enable project specific settings”->”Rebuild class files modified by others”

Thanks Phillip,
Deleteing the project and re-importing it into the workspace was what it needed.

Many thanks for this blog contribution, Philip.

It helped me solve a vexatious problem on which I spent a lot of time trying to solve.

I finally saw the parallel between your problem and mine, and I finally could say: SOLVED.

Many many thanks
