title: docker sonarqube checkdependency plugin
body: <p>I am trying to install the checkdepency plugin using docker Sonarqube, and PostgreSQL. I am able to get the docker SonarQube with PostgreSQL up and running, but when I try to add the check-dependency-plugin, it fails to restart the container. Is there any way to install the plugin? I am using SonarQube version 5.4 and the official PostgreSQL image from dockerhub. When I try to deploy the plugin, I am getting the error below. </p>
