/**
 * <p>Declares that the associated task can be run in parallel with other tasks belonging to the same project.</p>

 * <p>This annotation is not inherited which means that a task type that has a parallelizable super type is not parallelizable unless it's annotated with <code>@ParallelizableTask</code>.
 * A task that has custom actions (i.e. ones added via {@link org.gradle.api.Task#doLast(org.gradle.api.Action)} or {@link org.gradle.api.Task#doFirst(org.gradle.api.Action)}) is not
 * considered parallelizable even if its type carries this annotation.</p>
 *
 * <p>It is the responsibility of the implementer to make sure that a type annotated with <code>@ParallelizableTask</code> is actually thread safe.</p>
