[MJAVADOC-720] sourcepath does not work with aggregate goal

**[Christoph Schulz](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER293382)** opened **[MJAVADOC-720](https://issues.apache.org/jira/browse/MJAVADOC-720?redirect=false)** and commented

In our project we use lombok.

For the JavaDocs we delombok the sources using the Lombok plugin and add the output directory (`${project.build.directory}/generated-source/delombok`) to the `sourcepath` option.

This works fine for the non-aggregated reports, but it does not work for the aggregated report, with the sourcepath configured the report simply never executes (no `Generating "Javadoc" report --- maven-javadoc-plugin:3.3.2:aggregate-no-fork`).

Is this a know issue? Otherwise I can provide a project to reproduce this.

Investigate the aggregate goal in the Maven Javadoc Plugin 3.3.2 with a project using Lombok, the Lombok plugin, and `${project.build.directory}/generated-source/delombok` as `sourcepath`. Start by reproducing the difference between non-aggregated and aggregated reports; done means the aggregate report executes with that sourcepath configured.
