Description Krzysztof Daniel

Build ID:  I20081030-1917

Steps To Reproduce:
1. Create user library with external jar
2. Invalidate it renaming the parent folder of the jar
3. Add the user library to java project
4. Note the error message:
Project 'JP' is missing required library: 'C:\path\lib.jar'
5. Fix the path
6. Clean the project -> there is still an error

The user ends with a project which cannot be built.

WTP provides "Update EAR libraries" command which is able to refresh user libraries, but if someone uses clean Eclipse, this may be a problem.

The only way to build a project it to remove library, try to build the project, and then add library again.

I have found out that regular Refresh (F5) does the thing. 

This is not obvious for me - I found it in the javadoc.

I am leaving this bug open, lowering severity to enhancement.
Maybe it would be good to put this somewhere in the documentation, although closing as invalid is fine for me, too.

Indeed, Project > Clean cleans out the output of the various builders on the project. Its intent is not to refresh external libraries.

No action planned.
