Clean "deploy" folder

Sure, see File already exists error - #2 by viktorbenei for example

Or tweak/set the Gradle Runner step’s APK file include filter input. The default value is *.apk, to copy all generated APKs into the deploy directory, but you can change this to e.g. */app-knee-generic-development-debug.apk (based on your log) to only copy the app-knee-generic-development-debug.apk to the deploy directory.
