[StevenMassaro]

Impact

• Bug fix (non-breaking change which fixes expected existing functionality)
• Enhancement/New feature (adds functionality without impacting existing logic)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

Local builds of the liquibase-maven-plugin did not contain the pro code.

Things to be aware of

Things to worry about

This should only affect people who have the pro code checked out. If it affects other people, that is undesirable.
