If Clion, are there any options for integrating gradle into the IDE nicely, or command line only?

There is no support of Gradle on CLion yet. It’s the reason of CMake support

The incongruence of having good build support in one IDE and debugging environment in another IDE is a pain point. Since I'm working with mobile development, I've resorted to using AppCode for IDE based debugging (setting breakpoints, inspecting variables) while using VSCode as a lightweight editor since AppCode does not support Kotlin yet.

That's why it's bleeding edge...I wouldn't use it for anything production related 🙂

The frustration is it’s sooo close in intellij
