What's new in V2?

This plugin has been upgraded to V2 of the New Relic Platform Java SDK. For version 2 of the Java SDK, we have made several changes to help make the installation experience more uniform for plugins. The changes include:

  • '' file is now 'newrelic.json'
  • Plugin configuration is now done through the 'plugin.json' file
  • Logging has been made more robust and easier to use.
  • Jar distributables now have a well-defined name (i.e. plugin.jar)
  • Configuration files are now located in a well-defined location (i.e. './config' off the root)

More information on these changes (including how to configure logging, license keys, and the plugin itself) can be found here: If you have any feedback, please don't hesitate to reach out to us through our forums here:
