Subject [jira] Updated: (MNG-1889) Plugins without descriptors
Date Thu, 02 Aug 2007 05:31:13 GMT


Brett Porter updated MNG-1889:

    Fix Version/s:     (was: 2.0.x)

> Plugins without descriptors
> ---------------------------
>                 Key: MNG-1889
>                 URL:
>             Project: Maven 2
>          Issue Type: Bug
>          Components: Plugin Creation Tools
>    Affects Versions: 2.0.1
>            Reporter: Jochen Wiedmann
>            Priority: Minor
>             Fix For: 2.0.7
>         Attachments: maven-no-plugin-descriptors.patch, numMojoDescriptors.patch
> The attached patch throws an exception, if no Mojos are found in a plugin.
> Background: If such a plugin is installed, then an NPE is caused in the DefaultLifeCycleExecutor,
which properly assumes, that a plugin contains Mojo descriptors. Obviously, the actual error
is in the plugin itself, where it should be exposed. It took me some hours to find this actual
reason. (I still do not know, why the Mojos aren't found in my plugin, but that's another
story.) The patch should be able to save the same number of hours for other plugin developers.
> Note: The InvalidPluginDescriptorException, which is triggered by the patch, is possibly
not proper. I choosed it, because it allowed to leave the method signature unchanged and keep
the patch simple. It is up to the reviewer to choose another exception.
