No configuration setting found for key typesafe config

The error message is telling you that whatever configuration got read, it didn't include a top level setting named add. The ConfigFactory.load function will attempt to load the configuration from a variety of places. By default it will look for a file named application with a suffix of .conf or .json. It looks for that file as a Java resource on your class path. However, various system properties will override this default behavior.

So, it is likely that what you missed is one of these:

• Is it possible that src/main/resources is not on your class path?
• Are the config.file, config.resource or config.url properties set?
• Is your application.conf file empty?
• Do you have an application.conf that would be found earlier in your class path?
• Is the key: add defined in the application.conf?

Are you using an IDE or sbt? I had a similar problem while using Eclipse. It simply did not find the application.conf file at first and later on failed to notice edits. However, once I ran my program via sbt, all worked just fine, including Eclipse. So, I added 'main/resources' to the libraries (Project -> Properties -> Java Build Path -> Libraries", "add class folder"). That might help you as well.
