Does anyone know if there is a an Intellij inspection or a lint rule that can mark dependencies as unused?

class SomeActivity @Inject constructor() {
    @Inject
    lateinit var notUsed: UnusedClass
}

Over the years, classes have built up with unused dagger classes

@Inject

properties . It’s hard to clean this up manually over an entire codebase.

Not sure what you mean by “classes have built up unused dagger classes”.If your trying to suppress a warning you can do @SuppressWarnings(“unused”)

error prone is for Java

ahh I see, so there is no kotlin integration for it

it's a Java compiler

Not sure what you mean by “classes have built up unused dagger classes”.

Sorry, I’ve updated the grammar.

Interesting, even though I have used it in a codebase that had both Java and Kotlin, and it was still able to issue code improvement suggestions to the dagger modules.
