+
+**Implement lastModified check for sources**
+
+ * The annotation processor should be able to skip the annotation
+ * processing if the sources haven&#39;t changed since the last processing.
+ * This will speed up project builds considerably since for example the
+ * JPA metamodel generator will not run if the entities haven&#39;t been
+ * modified, which will save the compiler of having to recompile your
+ * whole module.
+ * Using the option `skipWithoutSourceChanges` you can enable this
+ * behavior. By default it is turned off to maintain the current behavior.
+ * This change doesn&#39;t track individual files, as there need not be a 1-1
+ * mapping between the origin of the annotation processor and the
+ * generated sources. The plugin rather determines from all source
+ * locations what the most recent last modified time is, and does the same
+ * for all the files in the output folder.
+ * This cuts down rebuild times on my current project by a half or so
+ * (going from over 2 minutes to just 1 minute).
