changed build.gradle to use java 1.6 (this got rid of @Override compile
errors)

added eclipse in gradle.bat file (might not be neccesary with gradle
STS plugin)

added default serialVersionUID to suppress warning, assuming
serialization will not be used.
changed include to import, someone was doing a bit too much python
before...
