I recently had to reinstall my os – a full clean install.
I did copy my eclipse workspace folder, to retain all data.
When I have everything setup again, 2 of 7 projects have red exclamation marks on them.
Why is this? I have checked all build paths that I know of and I have found no errors, and there are no errors in the actual code – so what is the issue?
This turned out to be an invalid build path in my project settings.
