Subject: [PATCH] Require Java 1.8 to build, bump maven-plugin-plugin version

Previously, we required Java 1.6 to compile (a corresponding entry had
to be made in ~/.m2/toolchains.xml), however the code already required
try-with-resources (HelpMojo).

Bump source code compatibility to Java 1.8, and remove the JDK 1.6
requirement from Maven POM files.

Also update the maven-plugin-plugin version, which seems to fix a
related problem when running with newer Maven environments.
