I have 2 files gradle look like this:
in backend module i can use Coroutine library, but i can not use kotlinx.Time
it make me so confuse
build.gradle.kts(backend)

plugins {
  id("kotlin-platform-jvm")
  id("kotlin")
  application
}

group = "xxx"
version = "1.0-SNAPSHOT"

repositories {
  jcenter()
}
dependencies {
  implementation(project(":shared", "default"))
  //…
}

application {
  mainClass.set("ServerKt")
}

build.gradle.kts(shared)

You can use dependencyInsight and dependencies tasks to get information about what lib makes it to where and why.
