Eclipse Neon with JDK 7 or lower

Question

When I compile / run the build on ant using eclipse neon on JDK 7 and below, I got an error Unsupported must run on 1.8 or higher. If I changed my ant and jdk from 8 to ant, I got unsupported minior/major version....

Is there a way to build using jdk 7 and below using eclipse neon? if I do this update, will I sacrifice all my previous changes and developments?
