Error uploading site: Failed to transfer file: Return code is: 401 ->

Question

I'm unable to deploy the site made by the maven-site-plugin.

I get similar errors as in this question: Maven site deploy logs filling with [WARNING] Required credentials to nexus 3 but there is an comment in it which says that the issue is known and reported here https://issues.sonatype.org/browse/NEXUS-10112 but this issue is closed.

I followed the tutorial http://books.sonatype.com/nexus-book/reference/_creating_a_new_maven_project.html everything is fine till the step 20.6 the site:deploy.

The only "solution" I found to this problem is here https://benkiew.wordpress.com/2009/11/27/status-code-401-on-mvn-sitedeploy/ but it doesn't work. My settings.xml and pom.xml match, so it is not the issue.

The settings.xml server conf looks as follows:

   </servers>
    <server>        
      <id>nexus</id>        
      <username>XXXX</username>
      <password>XXXX</password>
    </server>
   </servers>

And the parent pom.xml:

      <site>
          <id>nexus</id>
          <name>service-agents-repository</name>
          <url>dav:https://!URL!/repo/content/sites/agents</url>
      </site>

The id of provided by nexus is different as the two shown above, but I tried also with that ID, and I'm writing this question so didn't work. Error output by mvn site:deploy

Answer 1

It seems you've followed the documentation for Nexus Repository Manager 2. You might try the docs for Nexus 3 specifically: http://books.sonatype.com/nexus-book/3.0/reference/raw.html#_configuring_maven_for_site_deployment

If that doesn't help, let me know what version of Nexus 3 you are running, we made some changes to the realm name in 3.0.2 versus 3.0.0, although I don't think that is the issue.

Answer 2

Sorry about the question.

There was error. The problem was that Maven was pointing to wrong settings.xml file and was not getting the credentials. Therefore the configuration shown here is fine.

Thanks.
