To preface, I've been trying to figure out how to add cats-free as a dependency for my SLP mod for about a week.

Most of the issues have been about two things: the compile only custom cats version, and the fact that cats and all its dependencies are wrapped in scalablecatsforce at runtime. For the first issue, I've set the version of the custom cats version as strict, which seems to solve the version conflict, but that still leaves the runtime issue.

I've tried two approaches to solving this. Calling transitive(false) for cats-free removes all extraneous dependencies, but even though all its dependencies exist both at runtime and compile time, a classDefNotFoundError appears for cats.Foldable when calling foldMap on my Free dsl. I also tried to use dependency substitution, replacing cats core, kernel, etc. with ScalableCatsForce on the runtimeClasspath configuration. However, though this seems to fix gradle's reported runtimeClasspath, minecraft's runClient still contains all the unmodified typelevel dependencies. (Note: as advised by others, I'm using a custom configuration extending implementation to load cats-free and its dependencies to minecraft's classpath. I assume the dependency substitution problem has something to do with this, but I don't know why)

Is there something I can do to fix this as it is, or am I going about this all wrong?

After a git clone and immediate ./gradlew build:

I get the error message:

====

Project evaluation failed including an error in afterEvaluate {}. Run with --stacktrace for details of the afterEvaluate {} error.

• Where:
  Build file '/home/porl/workspace/minecraftmods/1.15.2/SLP-example/build.gradle' line: 93

• What went wrong:
  A problem occurred evaluating root project 'SLP-example'.

Could not find method implementation() for arguments [{group=org.typelevel, name=cats-core_2.13, version=2.1.0}] on repository container of type org.gradle.api.internal.artifacts.dsl.DefaultRepositoryHandler.

Do I need to do anything else before calling the build task?
