Liquibase Hibernate missing SequenceStyleGenerator.generatorKey() error

Question

I am trying to generate a diff changelog using Liquibase and Hibernate but when I run the command gradle diffChangeLog I get the following error:

ERROR [liquibase.integration.commandline.Main]: Unexpected error running Liquibase: 'java.lang.Object org.hibernate.id.enhanced.SequenceStyleGenerator.generatorKey()'
java.lang.NoSuchMethodError: 'java.lang.Object org.hibernate.id.enhanced.SequenceStyleGenerator.generatorKey()'

I am able to generate a changelog, but only get issues when trying to generate a diff changelog. My build.gradle.kts file is below:

    plugins {
        java
        id("org.springframework.boot") version "2.6.2"
        id("io.spring.dependency-management") version "1.0.11.RELEASE"

                            "org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy")
        }
    }

I have tried to change the versioning around but then get an error saying the driver could not be found.

Any help would be greatly appreciated! Thank you
