             Summary: Using "requires static transitive" makes javadoc goal fail
                 Key: MJAVADOC-677
                 URL: https://issues.apache.org/jira/browse/MJAVADOC-677
             Project: Maven Javadoc Plugin
          Issue Type: Bug
          Components: javadoc
    Affects Versions: 3.2.0
         Environment: Zulu JDK 16.28+11-CA (build 16+36)
Mac OS 10.14.6
            Reporter: Anand Beh
         Attachments: Javadoc-Modulepath.zip

Depending on a module using "requires static transitive", and then depending on that module, breaks javadoc execution.

*Summary*

Module org.checkerframework.checker.qual exists.

Module A "requires static transitive org.checkerframework.checker.qual"
 * Running the javadoc plugin on module A always succeeds.

Module B requires module A.
 * Running the javadoc plugin on module B fails with "module not found: org.checkerframework.checker.qual"

This happens only when Module A uses "requires static transitive" on an automatic module. If Module A "requires" or "requires transitive" or "requires static" checker-qual, the javadoc succeeds on Module B.

It does not matter whether checker-qual is an automatic module or a full module. The reproducer includes hsqldb 2.6.0 which is a full module, and the same error occurs.

*Reproducer*

Attached.

*Cause*

In target/apidocs/options, the javadoc plugin places checker-qual on the classpath with "--class-path".

If checker-qual is placed on the module-path, javadoc execution succeeds. This is demonstrated by editing the options file to place checker-qual on the module path, and running "javadoc @options @argfile".

The issue looks like it stems from plexus-java's LocationManager which returns a module-path consisting of required modules but ignoring statically-required modules: [https://github.com/codehaus-plexus/plexus-languages/blob/c1c07b59179bfafd3e80ce82ddd53dae1b2867a7/plexus-java/src/main/java/org/codehaus/plexus/languages/java/jpms/LocationManager.java#L405]

*General Solution*

Modules specified by "requires static transitive" need to be replaced on the module-path rather than class-path.
