Assignee: Brett Porter
Resolution: Not A Bug
this is because the mojo is not listed here:
http://repo2.maven.org/maven2/org/codehaus/mojo/maven-metadata.xml
for it to work from the command-line without a metadata entry, it must be
listed in the section, not the section (which is only
triggered during the 'site' lifecycle).

> 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

> 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}
>
> Maven Dashboard Report Plugin
> dashboard
> dashboard-maven-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}
>
> org.codehaus.mojo
>
> {code}
> But that did not work either...
