Is it allowed to redistribute a modification of BSD licensed software on OSSRH with my Maven groupId?

Question

I modified a BSD licensed software and proposed the patch to the contributors. I has been discussed and refused. I'm respecting the decision not to merge the changes, however I want to provide the modification in an easy accessible way.

I have an OSSRH account for a namespace that differs from the namespace of the original software. Is it ok if I upload the original software + my changes + a modification to build.gradle with my OSSRH namespace?

I'm aware of alternative ways of distributing my modification. I'm interested in the correctness of this particular approach.

Answer 1

Yes, that is allowed.

The license explicitly gives permission to distribute the software with modifications. The only conditions to that are that you retain the copyright notice and license text.

For your changes, you can put in your own copyright notice.
