Now you need to add the Regatta Hibernate Dialect to your pom.xml: 
<dependency>
    <groupId>dev.regatta</groupId>
    <artifactId>regatta-jdbc</artifactId>
    <version>1.0.0</version>
    <scope>system</scope>
    <systemPath>path/to/regatta_jdbc.jar</systemPath>
</dependency>
<dependency>
    <groupId>dev.regatta</groupId>
    <artifactId>regatta-hibernate</artifactId>
    <version>1.0.0</version>
    <scope>system</scope>
    <systemPath>path/to/regatta_hibernate_dialect.jar</systemPath>
</dependency>
