Description

sample project is attached, so to reproduce, either unzip it and run mvn javadoc:javadoc or follow following steps:

• have a simple jar project with a simple class/interface and module-info.java
• define compiler(3.8.1) and javadoc(3.1.1) plugins
• set 'release=11' for both
• on the command line with JDK 11.0.4 run mvn javadoc:javadoc

=> fails with:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:3.1.1:javadoc (default-cli) on project jdocbug: An error has occurred in Javadoc report generation:
[ERROR] Exit code: 1 - error: module not found: org.jdocbug
[ERROR]
[ERROR] Command line was: /Library/Java/JavaVirtualMachines/jdk-11.0.4.jdk/Contents/Home/bin/javadoc @options @packages @argfile
[ERROR]
[ERROR] Refer to the generated Javadoc files in '/Users/lukas/NetBeansProjects/jdocbug/target/site/apidocs' dir.
[ERROR]

Expected behaviour is that javadoc for current project is generated in target/site/apidocs folder.

looking into options file generated by the plugin:

• patch-module option looks strange there
• either source-path is missing or module-source-path points to wrong directory
