Installing Sonatype Nexus Open Source

Sonatype Nexus Open Source (Nexus OSS) is a repository manager for maven repositories.

Prerequisites

Maven

Versions used

Nexus OSS 2.0.5-04

Maven 3.0.4

Steps

• Download the nexus oss zip package from http://sonatype.org/nexus
• Extract the zip file to a folder created for nexus e.g. C:\nexus
• Installation is complete

Running nexus

• Open a command prompt window and navigate to the the NEXUS_HOME\bin directory e.g. C:\nexus\nexus-2.0.5-04\bin\
• Run the command nexus.bat console
• Open a browser and navigate to localhost:8081/nexus. The nexus interface should be displayed.
• To install nexus as a service, run the command nexus.bat install
• The nexus service name is nexus-webapp. Now you can start/stop nexus like any other service e.g. using the command net start nexus-webapp. To uninstall the service, run the command nexus.bat uninstall
• On the nexus home page, click on the Log In link. The default login username/password is admin/admin123. There is also a default deployment user with username/password deployment/deployment123. You can change any of these passwords by expanding the Security section on the left hand pane, selecting the Users option, right-click on the desired user and selecting the Set Password context menu.

Configuring maven to use nexus

• You can set maven to look for artefacts from nexus instead of directly from the internet e.g. the maven central repository. A Nexus proxy repository acts as a local cache for a remote repository.
• Create or edit the USER_HOME_DIR\.m2\settings.xml file e.g. C:\Users\ANDY\.m2\settings.xml, to configure nexus as the mirror for all repositories e.g.

  
    
      
      nexus
      external:*
      http://localhost:8081/nexus/content/groups/public
    
  
  
    
      nexus 
      
      
      
        
          central
          http://central
          true
          true
        
      
     
        
          central
          http://central
          true
          true
