java.lang.ClassNotFoundException: kotlin.coroutines.jvm.internal.CoroutineImpl

See original GitHub issue

my build.gradle:

buildscript {
    ext.kotlin_version = '1.3.0-rc-190'
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
apply plugin: "kotlin"
group 'com.lxj'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}
dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:${kotlin_version}"
    testCompile group: 'junit', name: 'junit', version: '4.12'
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.0.0-RC1'
}
compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

my code is:

fun main(args: Array<String>) {

    GlobalScope.launch{
        print("I am from coroutines")
    }
}

the console output:
