Where can I find a JPA2 Maven dependency?

I know this is a quite old post, if you want to go agnostic from the implementation, then you should use the Java EE API dependency instead.

Just add to your POM:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>${jee.version}</version>
    <scope>provided</scope>
</dependency>

Where the ${jee.version} is your desired Java EE version. I’m currently using 7.0. It has all EJB, JPA and JSF APIs dependencies.
