["jochenw (via GitHub)" <gi...@apache.org>]

jochenw commented on issue #1118:
URL: https://github.com/apache/maven-javadoc-plugin/issues/1118#issuecomment-4189378686

   For the record:
   
   1. I can reproduce the issue as follows:
   
   ``` bash
   cd /c/tmp
   rm -rf afw
   git clone https://github.com/jochenw/afw.git
   cd afw
   git checkout bfbd3129e52e5b798d4b1df1389269a7c3bdc05a
   cd afw-di
   mvn3 -V clean javadoc:javadoc
   ```
    This produces the following output:

   2, The issue **might** be related to problems in my module-info.java. (This is my first attempt on module programming.) If I change the Maven goals from "clean javadoc:javadoc" to "clean package javadoc:javadoc", then I get the following output from the CmdModuleNameExtractor:
