Hi. Replying to my own question:
> In particular, in the above log excerpt, I can't understand the lines saying: > > authentication: k='Sonatype Nexus Repository [email protected]' > c='null' This was indeed the problem. The "Sonatype Nexus Repository Manager" string indicated above *must* be set as the "realm" attribute in <credentials>. I think that it would be worth mentioning such pitfalls in the documentation...
