+Force execution
+
+ The hibernate4-maven-plugin computes MD5-sums for all found annotated
+ classes and stores them together with the generated schema.
+ If no classes were changed or added and the dialect wasn't changed too, it
+ automatically skips the configured schema-export, to speed up the development
+ cycle.
+
+ The plugin signals, that the execution was skipped by setting the maven
+ property <<<${hibernate.export.skipped}>>> to <<<true>>>.
+ This may be helpful, because other plugins like
+ {{{http://mojo.codehaus.org/dbunit-maven-plugin/}dbunit-plugin}}
+ {{{./pitfalls.html#fails}may fail}}, when the execution is skipped.
+
+ If you need the hibernate4-maven-plugin to <never skip automatically>
+ execution, you can force it to do so, if you set the parameter <<<force>>> to
+ <<<true>>>:
+
+----------------
+<plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate4-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <configuration>
+ <force>true</force>
+ </configuration>
+</plugin>
+----------------
+
+ Or you may specify <<<-Dhibernate.export.force=true>>> at the command line,
+ if you want to force hibernate4-maven-plugin only once.
