Maven: Failed to deploy artifacts, Acces denied

Question

I have a Sonatype Nexus server and I want to deploy a snapshot.

This is a snippet of my settings.xml file:

<servers>
  <server>
    <id>test-snapshots</id>
    <username>myname1</username>
    <password>mypasswd1</password>
  </server>
  <server>
    <id>test-releases</id>
    <username>myname2</username>
    <password>mypasswd2</password>
  </server>
</servers>

And this a snippet of my pom.xml file:

<distributionManagement>
  <repository>
    <id>test-releases</id>
    <name>Releases</name>
    <url>https://nxs.company.com/content/repositories/test-releases</url>
  </repository>
  <snapshotRepository>
    <id>test-snapshots</id>
    <name>Snapshots</name>
    <url>https://nxs.company.com/content/repositories/test-snapshots</url>
  </snapshotRepository>
</distributionManagement>

Doing a mvn deploy (Maven 3.0.3) I get this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy 
(default-deploy) on project MyProject: Failed to deploy artifacts: 
Could not transfer artifact com.company.project:MyProject:jar:1.0.0-20121003.154427-1

-> [Help 1]

And in my Nexus logfile, I see that no credentials are received, so it will try it later with anonymous and this will of course fail. So why are no credentials passed to Nexus?

Answer 1

Do you really have different username/password for each repository in Nexus? This will cause a problem with the maven http wagon because the jvm caches credentials per host and even though maven presents the alternate credentials properly, the jvm won't use them. The workaround to this is to use the webdav wagon instead since this uses the apache http client instead of the jdk urlclient.
