Plugin verifier report duplicate plugin descriptors when combined JAR is used

What happened?

With the new pluginModule(implementation(project(":plugin-java"))) syntax, the plugin verifier reports an error about duplicate jars.

Relevant log output or stack trace

The configuration file 'appmap-java.xml' for optional dependency 'com.intellij.java' failed to be resolved: Found multiple plugin descriptors 'appmap-java.xml' from 'intellij-appmap-0.67.0.jar' and 'appmap-java.xml' from 'plugin-java-base.jar'.

Steps to reproduce

Add the dependency listed above.

I'm not sure if the plugin verifier is the culprit here.
The plugin.zip contains the compose jar and also all the sub-module jars, which were already merged into the composed jar.
