如何明确告诉shadowJar使用 Kotlin 文件作为结果的入口点uberJar？JAR（或者，你喜欢胖。）

笨拙地编辑META-INF/MANIFEST.MF并在 zip 文件中替换它（使用 GUI 将其放回原处）：

各种成功。它按预期运行了 Kotlin 类。

13 directories, 9 files

构建文件： 

plugins {
    id 'com.gradle.build-scan' version '1.8' 
    //   id 'java'
    id 'application'
    id "org.jetbrains.kotlin.jvm" version "1.1.51"
    id 'com.github.johnrengelman.shadow' version '2.0.1'
}

buildScan {
    licenseAgreementUrl = 'https://gradle.com/terms-of-service'
    licenseAgree = 'yes'
    //publishAlways()
}

configurations {
    provided
}

shadowJar {
    baseName = 'kotlinAdder'
    classifier = null
    version = null
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

//mainClassName = 'net.bounceme.dur.kotlin.App'
mainClassName = 'demo.MainKt'

repositories {
    jcenter()
}

configurations {
    provided
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:1.1.51"
    compile 'com.google.firebase:firebase-auth:11.4.2'

}

我如何告诉 gradle 继续使用shadowJar但构建MANIFEST.MF手动编辑的，Main-Class: demo.MainKt明确设置为入口点。

否则，即使我在文件中明确设置了上述入口点，Java 代码也会默认运行 。build.gradle
