Build jar with IDEA throws error but fine with Gradle

Support

I too have this problem.
Idea version is 2017.2.1
I do next:

  1. Create new project Gradle->Kotlin
  2. Create main file in folder kotlin
  3. Create new default artifacts
  4. Build artifacts
  5. Run app:

java -jar Test.jar
no main manifest attribute, in Test.jar

My generated Mainfest is:

Manifest-Version: 1.0
Main-Class: MainKt

Manifest from jar file is:

Manifest-Version: 1.0
Implementation-Title: kotlin-stdlib-jre7
Kotlin-Runtime-Component: Main
Kotlin-Version: 1.1
Implementation-Version: 1.1.3-2
Build-Jdk: 1.8.0_131
Implementation-Vendor: JetBrains

build.gradle file is:
group ‘org.test’
version ‘1.0-SNAPSHOT’

buildscript {
ext.kotlin_version = ‘1.1.3-2’

repositories {
    mavenCentral()
}
dependencies {
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

}

apply plugin: ‘kotlin’

repositories {
mavenCentral()
}

dependencies {
compile “org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version”
}

compileKotlin {
kotlinOptions.jvmTarget = “1.8”
}
compileTestKotlin {
kotlinOptions.jvmTarget = “1.8”
}
