Order Maven Versions Plugin to use specific repositories only - maven

Question

Maybe this is too granular, but I would like to order Maven Versions Plugin to use only specific repositories to check for (new versions). The reason for this is: I want the plugin to check only internal company dependencies (from local Nexus) and there is no reason why we should check external repos. (Takes some times and it's also a security issue in a way). I have the following setup in the parent ("config") POM:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>versions-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<includes>
<include>com.mycompany.*:*</include>
</includes>
<serverId>automation-nexus</serverId>
</configuration>
</plugin>
The config above works fine in terms of not updating "external" dependencies, but "com.mycompany" artifacts are still queried from all other repositories. As you can see, I tried to use <serverId>, but that was just a guess, and it doesn't seem to do any "filtering" (I guess this is just a way to use specific credentials)
Any ideas if this is feasible or not?

You have to change your settings.xml instead and not the versions plugin configuration like this:
<settings>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://localhost:8081/nexus/content/groups/public</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<!--Enable snapshots for the built in central repo to direct -->
<!--all requests to nexus via the mirror -->
<repositories>
<repository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
By using the above settings you will limit the access to the above group and furthermore you can search within the repository group instead of any external repository.
