How do I deploy just the sources jar from a maven project?

Question

We made a number of releases to our nexus repository without source jars attached. I would like to backfill the source jars for these releases.

What I tried to do was

1. checkout the tagged version that I wanted to upload sources for
2. update the pom with the attach-sources snippet
3. do a maven deploy

This failed with a 400 error code because the pom and artifact jar were already in the repository.

Is there any way to upload just the source jar?

Answer 1

you should be able to do this using maven deploy-file (this has the added benefit of generating the various file sums as well), details here (you would be using, among other things, "packaging=jar" and "classifier=source").

Answer 2

I think the simplest thing would be to just upload sources jar using 'curl'. You will not even need to make any changes for that.
