[fix JENKINS-28294] Improve the ERROR message when a Maven project is…

… launched with a java version < to the minimum version required by the master. (#58) Examples: * Jenkins >= 1.612 requires Java 7 thus Maven jobs must be launched with Java >= 7 * Jenkins >= 1.520 requires Java 6 thus Maven jobs must be launched with Java >= 6
