I used 'mvn clean install' and can't compile a project without any issue. But when working within IntelliJ, it reports it can't find a dependency. What's the issue?
Please see the two attachment. The 'deeplearning' is the dependency it's complaining. As you can see, it can be found in the "External libraries" in the panel in IntelliJ. But in the code editor, it has lots of red flags.
