How to get Maven JavaDoc Plugin to put JavaDoc in 'docs' directory?

I have found a workaround. It's not really a solution, but it avoids the problem.

• Delete the 'docs' directory during the clean phase.
• Generate the Javadoc the default way.
• Copy the Javadoc from the default output directory into the 'docs' directory during the package phase.

...
        org.apache.maven.plugins
        maven-clean-plugin
        3.5.0
              ${basedir}/docs
          true
        org.apache.maven.plugins
        maven-javadoc-plugin
        3.12.0
            javadoc
              jar
        org.apache.maven.plugins
        maven-resources-plugin
        2.6
            copy-resources
            package
              copy-resources
              ${basedir}/docs
                  target/reports/apidocs

If nobody answers, I'll eventually mark this as correct, but I'd still prefer a way to solve the actual problem.
