Build path: missing required library ?

In Eclipse, I opened a previous program that built successfully.
I found 26 errors: "project missing required library".
There were also about 26 subdirectories created, recursively, with the
project name.

How do I fix this ?

you remove physically those directories from windows explorer and close eclipse and open it again.
ret cleaning project, via Project>Clean...

Thanks. I tried Clean. The cascading are still in the project explorer.
select war/jar project right click properties-buildpath- remove/add jar.
compare the .project and .classpath files with the working project

I can't delete it. Windows delete error: "the name is too long".
How do I delete this ?
