Sonargraph Github Action

For Maven based Java project

We just released our first Github action. It works for all Maven based Java projects and will upload the metrics of your project to an instance of Sonargraph-Enterprise. By default we use the public instance which is free to use, but you can also use this action with your own instance. Sonargraph-Enterprise allows you to track metric changes over time and also supports the creation of badges in your README.md file to display important system metrics.
