Spring Boot and JPA 2.0

I want to downgrade JPA versions and use JPA 2.0. Spring Boot's Data JPA starter comes with Hibernate 4.3 which supports JPA 2.1. According to the docs, I should be able to do this in my build.gradle:

'org.hibernate:hibernate-entitymanager:4.2.16.Final'

However Hibernate 4.3 is still being used. And there is no way of changing the javax.persistence:hibernate-jpa dependency to 

'org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final'

Is this possible?

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

Seems I misinterpreted the Spring Boot guide. For anyone wanting to know the answer, it isn't as simple as Maven to just declare a version in the properties. But after looking into Gradle's docs on how replace dependencies, I came across this section: Substituting a dependency module with a compatible replacement

So essentially all I need to do is this:

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        // Use Hibernate 4.2
        if (details.requested.name == "hibernate-entitymanager") {
            details.useTarget "org.hibernate:hibernate-entitymanager:4.2.16.Final"
        }
        // Use JPA 2.0
        if (details.requested.name == "hibernate-jpa-2.1-api") {
            details.useTarget "org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final"
        }
    }
}

And voila!
