Maven: Repro for issue 3834

[rob975]

This is a PR that addresses apache/logging-log4j2#3834 (comment).
Command:

mvn -X package -pl :log4j-assembly-test -am

will show:

[DEBUG] Error retrieving POM of module-dependency: org.apache.logging.log4j:log4j-jul:jar:2.25.0; Reason: Some problems were encountered while processing the POMs:
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-surefire-plugin is missing. @ line 81, column 15
[WARNING] 'build.plugins.plugin.version' for org.codehaus.gmavenplus:gmavenplus-plugin is missing. @
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-clean-plugin is missing. @
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-enforcer-plugin is missing. @
[ERROR] 'dependencies.dependency.version' for com.google.errorprone:error_prone_annotations:jar must be a valid version but is '${error-prone.version}'. @

The assembly contains all dependencies, so the error seems non-blocking. I would not rely on it, though.

Hi @rob975,

Thanks for the example. I'll look into it to see if we manage to make the build fail.
