Import github fails due to an "-class.-jw.util.version.Version-" Invalid Version

This in in the relation the issue I have for import github and the version "-class.-jw.util.version.Version-" not validated

I found that it is related to the changes made on April 7th, particularly here: nexB/vulnerablecode@6f643c9. Commits before April 6th have not this issue.

I did install the requirements, did the git pull rebuild the image, tried in a new directory with fresh code, tried to twist the code but my hacks just make a mess :) .. Even tried to improve the regex but was creating a mess again.

By skipping(hacking) that original version I got many other Invalid versions like: 2.0.1rc2-git Which seems to be valid

Will keep posting here my findings :)
