/**
 * Mojo to check if no project generated class files (compile scope) contain calls to forbidden APIs
 * from the project classpath and a list of API signatures (either inline or as pointer to files or bundled signatures).
 * At least one signature must be given, using any of the corresponding optional parameters.
 * <p>
 * This Mojo exists since version 1.2, replacing the old <code>forbiddenapis:forbiddenapis</code> goal.
 * <em>In most cases its enough to rename the goal on update, the older v1.0 properties are still available.</em>
 * <p>
 * Since version 2.0 this Mojo defaults to run in the {@code 'verify'} lifecycle phase, before it was done in
 * {@code 'process-classes'} phase, which caused problems for some users (especially debugging tests).
 * @since 1.2
