-----------------------------------------

             Summary: jar goal fails with automatic module  (Regression from 3.2.0)
                 Key: MJAVADOC-747
                 URL: https://issues.apache.org/jira/browse/MJAVADOC-747
             Project: Maven Javadoc Plugin
          Issue Type: Bug
          Components: jar
    Affects Versions: 3.5.0, 3.4.1, 3.4.0, 3.3.2, 3.3.1, 3.3.0
            Reporter: Geoffrey De Smet


In optaplanner, we provide automatic module names for all our modules.
But some modules have a dependency with classes in the no-name package.
That was not a problem for the maven-javadoc-plugin, except since maven-javadoc-plugin 3.3.0 (including 3.5.0) it crashes the entire build.

This happens with dependencies on quarkus and on rewrite.
For example, for optaplanner-migrator that depends on rewrite-maven and rewrite-gradle:
{code:java}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:3.5.0:jar (default) on project reproducer:
