sbt: publish to corporate Nexus repository unauthorized

Question

Quick resolution

The required credential expects the exact realm as defined by nexus. See below how to find the one you have defined, but most certainly

Answer 1

Ivy uses the realm of the WWW-Authenticate header, which will have to match byte-for-byte equal to the one configured in your credentials file.

sbt-aether-deploy uses the same header, but uses Aether as its deployment mechanism. Ivy does not.

The easiest way of figuring out the value of the WWW-Authenticate header is by using cURL.

curl -X POST http://nexus/content/repositories/libs-snapshots -v > /dev/null

cURL will prompt you for a user and pass.

-v will add verbosity so you will be able to see the headers of the request and response.

Answer 2

I suspect that your credentials file path may be incorrect. Try changing this:

credentials += Credentials(Path.userHome / ".sbt" / ".credentials")

to that:

credentials += Credentials("c:/data/user/.sbt/.credentials")

or try directly to troubleshoot first:

credentials += Credentials("Sonatype Nexus Repository Manager", 
  "nexus.scala-tools.org", "admin", "admin123") 

If these don't work check that your credentials are valid.
