m2eclipse with nexus - Server returned status code 401: Unauthorized

[buyapentiumjerk]

Hi all,

Eclipse version Helios Service Release 2
Maven version 3.0.3
m2eclipse version 0.12.1.20110112-1712
Nexus version 1.9.1

I've installed m2eclipse into Eclipse and then I've installed Maven in my HD, I've configured Eclipse to use my local Maven installation.

My settings.xml file:

I've installed Nexus and everything is fine in http://localhost:8081/nexus/index.html#welcome, I can create repositories and I can see inside what artifacts they have.

My problem is when I run Eclipse, I get this error:

Unable to update index for nexus|http://localhost:8081/nexus/content/groups/public

seeing my logs I get this:

There is a problem with authentication but I'm using admin user and I can log in Nexus web manager. Also when I check my repositories if I copy paste their links to my browser and use admin user I can see my repositories with its artifacts in my browser. I assume that the problem is with Eclipse and m2eclipse plugin.

I've been around this for the last 2 days, I've read Nexus documentation and I'm all out of ideas. Any help will be much appreciated.

I don't need a proxy.

Thank you for your time,
bapj


----------------

I went from a java.io.IOException: Server returned status code 401: Unauthorized to a java.io.IOException: Server returned status code 404: Not Found, so I found out that I just needed Update Index in Nexus Webfront-end. Click Repositories, inside repository name right-click and select "Update Index". On my next Eclipse start It started to build indexes.

I've read all Nexus documentation, searched for Youtube videos but I just tried to rebuild indexes after looking at this page "B.2. Migrating Archiva Repositories" -> B.2.*Migrating Archiva Repositories | Sonatype.

Hope this information is helpful to someone else. :)
