Migrating JBPM core to use mysql in any maven project

I am trying to build a maven project. I am using Dropwizard maven project.
I have included below dependency :
<dependency>
<groupId>org.jbpm</groupId>
<artifactId>jbpm</artifactId>
<version>6.3.0.Final</version>
<type>pom</type>
</dependency>

<!-- https://mvnrepository.com/artifact/org.jbpm/jbpm-flow-builder -->
<dependency>
<groupId>org.jbpm</groupId>
<artifactId>jbpm-flow-builder</artifactId>
<version>7.4.1.Final</version>
</dependency>
