Every so often a project simply disappears from the Package Explorer
window. If I try to recreate it, it says it already exists. Also, the
folders are clearly still there under the workspace.
(In one case, I tried deleting the folders under the workspace and it
still said it was there. Finally, a File | Refresh gave a message about
missing files with the option to remove the project. That allowed me to
recreate it. Big hassle, though, setting all the libraries, preferences,
etc.)
In all these projects, the source files are linked from outside the
workspace folder hierarchy.
It is very puzzling when these projects are not visible, yet Eclipse knows
about them because it won't allow me to create a new one with the same
name.
(I have been running Windows Backup (not restore) lately; don't see how
that could cause it though.)
I would appreciate any help in troubleshooting this, or a way to force
projects to load. I searched and found a 2007 thread with a similar
problem, but no solution.
