/**
 * A plugin for the <a href="https://pmd.github.io/">PMD</a> source code analyzer.
 * <p>
 * Declares a <code>pmd</code> configuration which needs to be configured with the PMD library to be used.
 * <p>
 * Declares a <code>pmdAux</code> configuration to add transitive compileOnly dependencies to the PMD's auxclasspath. This is only needed if PMD complains about NoClassDefFoundError during type
 * resolution.
 * <p>

The PMD plugin adds the following dependency configurations:

| `pmd` | The PMD libraries to use
| `pmdAux` | The additional libraries that are available for type resolution during analysis. This might be useful if PMD complains about missing classes.
