archive for required library could not be read or is not a valid ZIP file

Question

Before coming to the problem let me explain what I did that has landed me in the problem.

1. I created an account on github and made a repository named Android.

Answer 1

I've seen the same issue. I removed that jar file, and then rightclick on the project, select maven, and do "update project...". The jar was downloaded again, and the problem was gone.
