             Summary: Java 9 banDuplicateClasses incorrectly sees module-info.class as duplicate
                 Key: MENFORCER-283
                 URL: https://issues.apache.org/jira/browse/MENFORCER-283
             Project: Maven Enforcer Plugin
          Issue Type: Bug
          Components: Plugin
    Affects Versions: 1.4.1
            Reporter: Sven Haster
            Priority: Minor


When running the enforcer plugin with banDuplicateClasses rule against a project with dependencies on java-9 compatible libraries which include a module-info.class file, the plugin sees the multiple module-info files as duplicate classes. 

It should simply ignore these similar to package-info.

In our projects, it is the dependencies on multiple libs from org.ow2.asm which provides the module-info class, rendering the following output:

{noformat}
[WARNING] Rule 2: org.apache.maven.plugins.enforcer.BanDuplicateClasses failed with message:
Duplicate classes found:

  Found in:
    org.ow2.asm:asm-tree:jar:6.0:compile
    org.ow2.asm:asm:jar:6.0:compile
    org.ow2.asm:asm-util:jar:6.0:compile
  Duplicate classes:
    module-info.class
{noformat}

We can easily work around this problem for now by adding a global rule to ignore module-info such as the following but it would be nice if the enforces plugin ignored this file by default.

{code:xml}
<banDuplicateClasses>
	<ignoreClasses>
		<ignoreClass>module-info</ignoreClass>
	</ignoreClasses>
</banDuplicateClasses>
{code}
