[jira] [Commented] (MPLUGIN-372) Descriptor generation does not
work when Mojo class hierarchy extends provided class
[ https://issues.apache.org/jira/browse/MPLUGIN-372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17357359#comment-17357359 ]
Tamás Cservenák commented on MPLUGIN-372:
-----------------------------------------
Just FTR a bit more about error: it happens when {{JavaAnnotationsMojoDescriptorExtractor}} tries to find some JavaDoc (!) tags in method {{populateDataFromJavadoc}} , more precisely the "deprecated" Javadoc tag. It does look in given class, then goes toward superclass(es). Seems, QDox throws up belly in this case (as super class, for example AbstractMojo is not on class, as it is provided scope). Error on CLI:

> Descriptor generation does not work when Mojo class hierarchy extends provided class
> ------------------------------------------------------------------------------------
>
> Key: MPLUGIN-372
> URL: https://issues.apache.org/jira/browse/MPLUGIN-372
> Project: Maven Plugin Tools
> Issue Type: Task
> Components: maven-plugin-tools-annotations, Plugin Plugin
> Reporter: Tamás Cservenák
> Priority: Major
>
> As part of work on MPLUGIN-370 took an example plugin (m-dependency-p) and just set it's maven dependencies to provided. Build exploded with NoClassDefFoundEx (usually for AbstractMojo). Nb: error reporting could be improved, as even with debug output nothing is said why this happened.
> Reason is that DescriptorGeneratorMojo sets ResolutionScope.RUNTIME that **excludes** provided dependencies (like maven-plugin-api, where AbstractMojo is).
> Setting the descriptor mojo scope to ResolutionScope.COMPILE_PLUS_RUNTIME make it work just fine.
> Anyone have any idea why Descriptor Mojo uses RUNTIME scope (hence, omits provided artifacts from processing)?
