Description

When running on a machine with only java 7, you cannot do a full compile of the project.

The error message is:
[WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireJavaVersion failed with message:
Detected JDK Version: 1.7.0-121 is not in the allowed range [1.8,).

The failed module is:
[INFO] Apache Beam :: SDKs :: Java :: IO :: Hadoop :: jdk1.8-tests FAILURE [ 37.549 s]

This is likely due to the enforcer rules at https://github.com/apache/beam/blob/master/sdks/java/io/hadoop/jdk1.8-tests/pom.xml#L39

without this exception to the enforcer rules, it throws errors since the cassandra dependency in that directory is java 8, so the intent is that enforcer should not error out since this module.

Below are the errors (well, warnings) when run with <version>[1.8,)</version> is commented out:
