Using multiple repositories in Maven

Question

I have a project that uses an internal repository and the central repository. Is there a way I can configure the settings.xml such that I can use both instead of just one? W

Answer 1

I use three repos (using Nexus), the first one is a Proxy repository to which I add all external repositories. The other two are my internal repositories for deployment of releases and snapshots. Here is my .m2/settings.xml:

    

    true
    false

    
    
        nexus
        external:*
        http://localhost:3129/nexus/content/groups/public
    
    

    
    
        nexus
        
            
                central
                http://central
                
                    true
                
                
                    true
                
            

            
                internal.releases
                http://localhost:3129/nexus/content/repositories/releases
                
                    true
                
                
                    false
                
                    

            
                internal.snapshots
                http://localhost:3129/nexus/content/repositories/snapshots
                
                    false
                
                
                    true
                
                    
        

        
            
                central
                http://central
                
                    true
                
                
                    true
                
            
        
        
            true
            true           
        
    
    

    
    nexus
      

    
    
        internal.releases
        admin
        XXX
    
    
        internal.snapshots
        admin
        XXX
    
    

Maven uses them all, so you might want to use the Routing feature of Nexus to block "^/my/private/packages/.*" so it does not try to fetch internal packages from external repositories. I haven't added the internal repos to the proxy repo.

You don't need to adjust your pom.xml files for that to work. Just enter "mvn deploy".
