I sorry for delay, but I have a solution. I have two archive, being: pom.xml and build.bat (build.xml). The build.xml has my configuration for generate the mapping of the hibernate.
I got it run (build.xml) through of pom.xml with below command (something similar the example of the Gilberto Torrezan).
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
<configuration>
<executable>ant/build_hibernate.bat</executable>
</configuration>
</plugin>
Thanks.
