Did you consider using travis-ci?

You just need the webhook and a .travis.yml file containing :

language: java

Setup travis-ci, and will be adding it to the project. However, build is currently wonky. Waiting on the influxdb-java project to push a new version that you don't have to install manually to make it work. See influxdata/influxdb-java#37

This is now done. I temporarily disabled the influxdb integration project, and will re-enable it when their issue is resolved.

To check on this, see : https://travis-ci.org/jtmelton/appsensor/

I also put a build badge on the main readme: https://github.com/jtmelton/appsensor/blob/master/README.md

Thanks @BrunoQC for the travis-ci suggestion.
