Must specify build file using --build-file after migrating to .kts file

[kworth]

No longer works on a project (internal to my company) after migrating build.gradle to build.gradle.kts.

I have tried adding rootProject.buildFileName = 'build.gradle.kts' to settings.gradle, but the only thing that has worked is specifying the file name at runtime. For instance typing the following ./gradlew --build-file build.gradle.kts cle and hitting tab completes clean.
