Recently I tried to create DDLs with the Hibernate 3 Maven Plugin. Since I was using Hibernate 4 this did not work. Since Hibernate 4 provides support for DDL generation, the integration into a Maven plugin proofed not to be very difficult.
I wrote a quick-and-simple Hibernate 4 Maven Plugin that provides just the DDL generation I needed. Please consider it not to be a replacement for the fine hibernate3-maven-plugin! But if DDL creation is all you need for Hibernate 4, the Hibernate 4 Maven Plugin might come handy to you.
The following POM fragment shows everything the plugin is currently (version 0.1.1) capable of:
<plugin>
<groupId>de.smartics.maven.plugin</groupId>
<artifactId>hibernate4-maven-plugin</artifactId>
<version>0.1.1</version>
<executions>
<execution>
<id>export</id>
<goals>
<goal>hbm2ddl</goal>
</goals>
</execution>
</executions>
<configuration>
<unitName>jpa-unitname</unitName>
</configuration>
</plugin>
