Finding unused methods in scala using Intelli J

Question

I am working on a scala project in IntelliJ and want to clean up my code. For this, I am looking for a way in which I can get a list of unused methods within my project.

This link didn't answer my question. It is for Java and not for Scala. Finding unused methods in IntelliJ (excluding tests)

Analyze -> Inspect Code for Scala in IntelliJ has an option to select unused symbol but I am unable to drill it down to only check methods.

As far as I know you can't get it any more specific. But anyways, unused vals and vars are at least as important as unused defs. – Psalterium

thanks bash0r. Yeah but I was thinking if there was any IntelliJ plugin to get this capability. – Conjunctive

Sorry, nothing I'm aware of. – Psalterium

Answer 1

Go to Analyze -> Inspect code Under Inspection Profile click on "..." and make sure "Unused declaration" is checked. Chose Whole project option and then OK.

Cannot find Unused Declaration under Scala language when I click on "...". When I filter, I can see only "Unused Symbol" under Scala. – Conjunctive

Try to search "unused declaration" in the search bar in the window that opened after you clicked on "..." – Adductor

I am still to find that option for Scala... for Java I can see it but haven't come across anything so far. – Jansenism

It doesn't seem to include the play framework references that occur in the generated code from the routes file. It ended up removing those functions... – Pires
