Philipp Ottlinger created MPLUGIN-507:
-----------------------------------------
Summary: NPE during plugin run to generate mojo descriptor /
worked in versions before 3.11.0
Key: MPLUGIN-507
URL: https://issues.apache.org/jira/browse/MPLUGIN-507
Project: Maven Plugin Tools
Issue Type: Bug
Components: maven-plugin-annotations
Affects Versions: 3.11.0
Reporter: Philipp Ottlinger
While working on broken links via RAT-353 I realized after adding the new
maven-plugin-report-plugin a NPE breaks the build and no site-related pages are
generated.
{code:java}

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR] mvn [args] -r
[DEBUG] Shutting down adapter factory; available factories [file-lock,
rwlock-local, semaphore-local, noop]; available name mappers [discriminating,

{code}
Thus there are no
* plugin-info.html
* check-mojo.html
* rat-mojo.html
in the site build, which prevents us from releasing RAT.
(btw: would it make sense to add a new component in your Jira for
maven-plugin-report-plugin?)
