What's the recommended way of updating maven repository metadata

Question

I'll like to know, what's the recommended way of updating maven repository metadata?

The scenario I'm working with is such that the content of maven-cargo plugin metadata is stale and does not reflect an updated repository metadata, hence, my reason to change it.

For example, I have this in maven-metadata-central.xml for the maven-cargo plugin:

<?xml version="1.0" encoding="UTF-8"?>
<metadata>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-cargo-plugin</artifactId>
</metadata>

Whereas the updated version should be this:

<?xml version="1.0" encoding="UTF-8"?>
<metadata>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>cargo-maven2-plugin</artifactId>
</metadata>

How do I go about this?

Thanks

Add below into settings.xml (This makes maven to use the specified group first.

<pluginGroups>
      <!-- pluginGroup
      | Specifies a further group identifier to use for plugin lookup.
      <pluginGroup>com.your.plugins</pluginGroup>
      -->
      <pluginGroup>org.codehaus.cargo</pluginGroup>
  </pluginGroups>

And add below into your pom.xml

<configuration>
   <container>
     <containerId>jetty6x</containerId>
     <type>embedded</type>
   </container>
 </configuration>
