The EE 6 classes are available in maven central.
<dependency>
<groupid>javax</groupid>
<artifactid>javaee-api</artifactid>
<version>6.0</version>
<scope>provided</scope>
</dependency>
But when running unit test against them you receive the below error. Thats because they do not contain implementation classes, only api class.
java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/persistence/LockModeType
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632)
at java.lang.ClassLoader.defineClass(ClassLoader.java:616)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141)
at java.net.URLClassLoader.defineClass(URLClassLoader.java:283)

at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
So in practice, the dependecy is in real life unusable. Instead you must use api classes from specific vendors like JBoss.
<dependency>
<groupid>org.jboss.spec</groupid>
<artifactid>jboss-javaee-6.0</artifactid>
<version>1.0.0.Final</version>
<type>pom</type>
<scope>provided</scope>
</dependency>
