在MANIFEST.MF中将Kotlin类指定为Main-Class入口点？

我如何明确告诉shadowJar使用Kotlin文件作为生成的uberJar的入口点？ （或者，你喜欢胖胖的JAR 。）

笨拙地编辑META-INF/MANIFEST.MF并将其替换为zip文件（使用GUI将其放回）：

 thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ ll total 900 drwxrwxr-x 2 thufir thufir 4096 Nov 5 03:42 ./ drwxrwxr-x 8 thufir thufir 4096 Nov 5 03:42 ../ -rw-rw-r-- 1 thufir thufir 903184 Nov 5 03:42 kotlinAdder.jar thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ jar xf kotlinAdder.jar thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ ll total 928 drwxrwxr-x 7 thufir thufir 4096 Nov 5 03:42 ./ drwxrwxr-x 8 thufir thufir 4096 Nov 5 03:42 ../ drwxrwxr-x 2 thufir thufir 4096 Nov 5 03:42 demo/ drwxrwxr-x 17 thufir thufir 12288 Nov 5 03:42 kotlin/ -rw-rw-r-- 1 thufir thufir 903184 Nov 5 03:42 kotlinAdder.jar drwxrwxr-x 3 thufir thufir 4096 Nov 5 03:42 META-INF/ drwxrwxr-x 3 thufir thufir 4096 Nov 5 03:42 net/ drwxrwxr-x 4 thufir thufir 4096 Nov 5 03:42 org/ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ nano META-INF/MANIFEST.MF thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ cat META-INF/MANIFEST.MF Manifest-Version: 1.0 Main-Class: net.bounceme.dur.kotlin.App thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ nano META-INF/MANIFEST.MF thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ cat META-INF/MANIFEST.MF Manifest-Version: 1.0 Main-Class: demo.MainKt thufir@dur:~/NetBeansProjects/kotlin/build/libs$ thufir@dur:~/NetBeansProjects/kotlin/build/libs$ java -jar kotlinAdder.jar Hello, world! thufir@dur:~/NetBeansProjects/kotlin/build/libs$ 

各种各样的成功。 它按预期运行Kotlin课程。

项目：

 . ├── build.gradle ├── gradle │  └── wrapper │  ├── gradle-wrapper.jar │  └── gradle-wrapper.properties ├── gradlew ├── gradlew.bat ├── settings.gradle └── src ├── main │  ├── java │  │  └── net │  │  └── bounceme │  │  └── dur │  │  └── kotlin │  │  └── App.java │  └── kotlin │  └── demo │  ├── example.kt │  └── main.kt └── test └── java 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' } 

如何告诉gradle继续使用shadowJar但是要手动编辑MANIFEST.MF ，将Main-Class: demo.MainKt明确设置为入口点。

否则， 即使在build.gradle文件中显式设置了入口点，Java代码也会 默认运行 。
