Is there a way to make Maven download snapshot versions automatically?

Question

So I have a project that depends on a snapshot version of another project. The dependency is:

  org.oop
  

        

Answer 1

To update snapshots, try with the -U option

-U,--update-snapshots                  Forces a check for updated
                                       releases and snapshots on remote
                                       repositories

However, you said:

I did do a 'mvn clean deploy', so the snapshot version should be somewhere in the maven central repository.

This is just not possible, your snapshot is going somewhere else. If I do a mvn clean deploy without configuring my personal repository I get:

Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter

To enable deployment, there is some configuration to be added to pom.xml, like for instance:

    
    
        myrepo
        My releases
        http://nexus.mycompany.com/nexus/content/repositories/releases
    

    
    
        myrepo
        my snapshots
        http://nexus.mycompany.com/nexus/content/repositories/snapshots
    




    
        myrepo
        My Public Repository
        http://nexus.mycompany.com/nexus/content/groups/public
        
            true
        
        
            true
