+* The database will not be recreated after a manual drop/clean
+
+ If one manually drops the database or removes the hsqldb-files, it will not
+ be recreated by the hibernate4-maven-plugin, because it cannot detect, that
+ the database needs to be recreated.
+ This happens, because the plugin will not recreate the database if neither
+ the configuration nor the annotated classes have changed, because an
+ unnecessary drop-create-cycle might take a long time. The plugin will
+ report that like this:
+-------------
+[INFO] No modified annotated classes found and dialect unchanged.
+[INFO] Skipping schema generation!
+[------------
+
+ If one always uses <<<mvn clen>>> for cleanup, this will not happen.
+ Otherwise the recreation must be forced:
+
+-------------
+mvn hibernate4:export -Dhibernate.export.force=true
+-------------
