> I have a simple test project that declares the dashboard-maven-plugin (see http://mojo.codehaus.org/dashboard-maven-plugin/usage.html ).
> Note that the usage does explicitly state that the Codehaus repository must be specified as a plugin repository...
> However, according to:  http://maven.apache.org/guides/introduction/introduction-to-plugin-prefix-mapping.html
> I'm pretty sure that Maven should be able to resolve the dashboard-maven-plugin from the central repo.
> I validated that the [dashboard-maven-plugin residing in central|http://repo1.maven.org/maven2/org/codehaus/mojo/dashboard-maven-plugin/1.0.0-beta-1/] is indeed the same artifact as that which lives at the [codehaus repository|http://repository.codehaus.org/org/codehaus/mojo/dashboard-maven-plugin/1.0.0-beta-1/].
> But as you can see from my attached test case, the codehaus mojo is NOT being resolved without the special plugin repository defined.  When running {noformat}mvn dashboard:dashboard{noformat}, I get the following error message:
> {noformat}
> [INFO] Scanning for projects...
> [INFO] Searching repository for plugin with prefix: 'dashboard'.
> [INFO] ------------------------------------------------------------------------
> [ERROR] BUILD ERROR
> [INFO] ------------------------------------------------------------------------
> [INFO] The plugin 'org.apache.maven.plugins:maven-dashboard-plugin' does not exist or no valid version could be found
> [INFO] ------------------------------------------------------------------------
> [INFO] For more information, run Maven with the -e switch

> If you edit the pom.xml to uncomment out the plugin repository declaration for codehaus, it works as one would expect.
> My understanding is that the only reason why the Dashboard Usage mentions their plugin repository is because the artifact was not available on the central repository -- but it certainly is today.
> I also thought that perhaps the maven-metadata.xml might be incorrect (perhaps the dashboard plugin prefix is missing or different).  I checked:
> * http://repo1.maven.org/maven2/org/codehaus/mojo/maven-metadata.xml
> * http://repository.codehaus.org/org/codehaus/mojo/maven-metadata.xml
> and they both look OK to me...  I clearly see:{code:xml}
> <plugin>
>     <name>Maven Dashboard Report Plugin</name> 
>     <prefix>dashboard</prefix> 
>     <artifactId>dashboard-maven-plugin</artifactId> 
> </plugin>
> {code}
> And I don't see any plugin with a dashboard prefix specified as an Apache Maven Plugin here:
> * http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-metadata.xml
> If I explicitly specify the dashboard plugin like:  {noformat}mvn org.codehaus.mojo:dashboard-maven-plugin:dashboard{noformat}
> that works...
> Overall, I am recording a bug because the [documentation|http://maven.apache.org/guides/introduction/introduction-to-plugin-prefix-mapping.html] states:{quote}
> Maven will always search the following groupId's after searching any plugin groups specified in the user's settings:
> * org.apache.maven.plugins 
> * org.codehaus.mojo 
> {quote}
> I don't see this being done.
> Finally, I even tried adding a {{pluginGroups}} to my {{settings.xml}}:{code:xml}
> <pluginGroups>
>   <pluginGroup>org.codehaus.mojo</pluginGroup>
> </pluginGroups>
> {code}
> But that did not work either...
