I have a dependency on a file-based jar implementation(files("libs/slf4j-android-1.6.1-rc1.jar")) that I want to exclude from configuration.testImplementation { exclude("org.slf4j"} but it doesn't seem to work. mockk is complaining that Log.i isn't a mock object

Yeah, of course it does not work, you are not depending on org.slf4j, you are depending on some file on your disk without any coordinates.

I strongly advice against any form of files or fileTree for dependencies, those have significant drawbacks. Instead use a flatDir repository and then normal dependency declarations. Then - if done right - your exclude will probably also work.
