Question

My project struct

("https://i.sstatic.net/EykkL.png")

Build.gradle content as below

apply plugin: 'java' apply plugin: 'kotlin' dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version" } sourceCompatibility = "1.7" targetCompatibility = "1.7" buildscript { ext.kotlin_version = '1.1.2-4' repositories { mavenCentral() } dependencies { classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } repositories { mavenCentral() } // override the sourceSet flow other answers. sourceSets { main.java.srcDirs+= 'src/main/java' main.kotlin.srcDirs+= 'src/main/kotlin' main.resources.srcDirs += 'src/main/resources' }

Exception when I run it

It may be compiled successfuly but when I run the kotlin codes. It throws the exception below. And the java codes run ok.

Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics at KotMainKt.main(kotMain.kt) Caused by: java.lang.ClassNotFoundException: kotlin.jvm.internal.Intrinsics at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 1 more

:kotlin-stdlib-jre8 doesn't like when you use sourceCompatibility = "1.7" — OneCricketeer

Android and kotlin-stdlib-jre8 don't really work together very well. Replace that will kotlin-stdlib and all should work — Kingsley Adio

I add the codes belows at build.gradle and fix this problem.

jar { manifest { attributes 'Main-Class': 'KotMainKt' }

from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }

}
