This will discuss setting up the Nexus Maven proxy.

Install Nexus

First, install Nexus. Nexus has excellent documentation on the subject.

Follow the directions in section 16.2 and you'll have a basic install set up.

Configure Repositories

To add a repository, log in to http://nexus-server:8081/nexus/ (login/password are admin/admin123 by default) and then click the "Repositories" link in the navigation menu on the left.

Then, click the +Add button at the top.

You will need to add the following repositories to be able to do full OpenNMS development (anything not listed here can be left as the defaults):

Configure Maven2 settings.xml

Next, you'll need to set up your ~/.m2/settings.xml to point to your newly-created nexus mirror.

If you have a <mirror> section already, you will need to determine what these should override yourself. Otherwise, you should be able to edit your settings.xml like so: 

 <settings>
   <mirrors>
     <mirror>
       <id>nexus-snapshots</id>
       <name>Nexus Public Snapshots Mirror</name>
