elharo opened a new issue, #386:
URL: https://github.com/apache/maven-help-plugin/issues/386
In src/main/java/org/apache/maven/plugins/help/DescribeMojo.java:333-338:
throw new MojoExecutionException(
"Error retrieving plugin descriptor for:" + LS + LS + "groupId: \x27" +
groupId + "\x27" + LS
+ "artifactId: \x27" + artifactId + "\x27" + LS + "version: \x27" +
version + "\x27" + LS + LS, e);
When the plugin was specified by prefix (e.g., -Dplugin=help), the mojo
fields groupId, artifactId, version are all null. The method parameter
PluginInfo pi contains the actual values but the error message ignores them.
Output shows groupId: \x27null\x27 etc. — misleading and unhelpful for
debugging.
