maven添加新的远程存储库

Question

How can I add a new remote repository in the maven user settings config file? I added a new option for the one with the id "softwarementors", but when I run the update target on the maven project, it simply redirects to the configured nexus server nexus_server_ip_address.

How can I prevent this? How do I need to adjust the maven config file in order to add a new remote repository. I replaced the nexus server's ip address with

Answer 1

The mirrorOf pattern of * causes any repository request to be redirected to this mirror and to your single repository group, which in the example is the public group.

Solution 1 : add softwarementors to Nexus

Solution 2 :
            Add this.

                <mirror>
                  <id>softwarementors</id>
                  <mirrorOf>softwarementors</mirrorOf>
                  <url>https://repository.sonatype.org/content/groups/forge/com/softwarementors/extjs/directjngine/2.2/</url>
                </mirror> 

                <repository>
                    <id>softwarementors</id>
                    <name>softwarementors</name>        
                    <url>https://repository.sonatype.org/content/groups/forge/com/softwarementors/extjs/directjngine/2.2/</url>
                </repository>

Solution 3:

<mirror>
       <!--This sends everything else to /public -->
       <id>nexus</id>
       <mirrorOf>*,!softwarementors</mirrorOf>
       <url>nexus_server_ip_address/nexus/content/groups/public</url>
</mirror>
