Kotlin 1.3-M2: new multiplatform projects model

As to shadow plugin (com.github.johnrengelman.shadow), the situation is as follows.

  • in case of using jvmWithJava target, it should work as is, just apply it from the top level of the build.gradle script. Note, hovewer, that the target is going to be deprecated as it’s already said above.

  • when using with jvm target, an additional task definition is needed, like the following:

      task shadowJar(type: com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar) {
          def target = kotlin.targets.jvm6
          from target.compilations.main.output
          def runtimeClasspath = target.compilations.main.runtimeDependencyFiles
          configurations = [runtimeClasspath]
  }

    — where jvm6 is the JVM target’s name.

    So overall build.gradle will look like:

      group 'com.example'
  version '1.0'

  buildscript {
      repositories {
          jcenter()
      }
      dependencies {
          classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.10'
          classpath 'com.github.jengelman.gradle.plugins:shadow:4.0.2'
      }
  }

  apply plugin: 'kotlin-multiplatform'
  apply plugin: 'com.github.johnrengelman.shadow'

  repositories {
      jcenter()
  }

  kotlin {
      targets {
          fromPreset(presets.jvm, 'jvm6')
      }
      sourceSets {
          commonMain {
              dependencies {
                  api 'org.jetbrains.kotlin:kotlin-stdlib-common'
              }
          }
          jvm6Main {
              dependencies {
                  api 'org.jetbrains.kotlin:kotlin-stdlib'
              }
          }
      }
  }

  task shadowJar(type: com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar) {
  	from kotlin.targets.jvm6.compilations.main.output
  	def runtimeClasspath = kotlin.targets.jvm6.compilations.main.runtimeDependencyFiles
  	configurations = [runtimeClasspath]

The support of kotlin-frontend plugin for JS is in progress right now, you may track the progress via this issue.
