How to exclude a single module from Javadoc generation in a Maven multi module project?

I have a Maven multi module project like this:

foo-parent
    foo-module
    foo-module-new
    foo-other-module1
    foo-other-module2
    pom.xml

And when calling mvn javadoc:aggregate in foo-parent, I want to exclude the module foo-module from Javadoc generation.

Exclusion by package name with the parameter excludePackageNames doesn't work in my case because foo-module and foo-module-new have the same package name.

Since maven-javadoc-plugin:3.2.0 you can use the skippedModules property to provide a comma separated list of modules to skip. For instance the following configuration would skip the foo-module module:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-javadoc-plugin</artifactId>
  <reportSets>
    <reportSet>
      <id>aggregate</id>
      <configuration>
        <skippedModules>foo-module</skippedModules>
      </configuration>
    </reportSet>
  </reportSets>
</plugin>

Alternatively, you may use the maven.javadoc.skippedModules user property to achieve the same outcome.
