Gradle Project: java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics

I'm working on a Java project and within this project I did my first try with Kotlin. I started converting some classes to Kotlin with the JavaToKoltin converter provided in the Intellij Idea. Among others my custom exceptions are now converted to Kotlin. But with this the exception handling does not work correct anymore.
If I throw one of my custom exceptions (e.g. MyCustomKotlinException.kt) within the java code, the exception is not catched (see code below).

// Example.java
package foo    

import java.util.*;
import java.lang.*;
import java.io.*;
import foo.MyCustomKotlinException;

class Example
{
    public static void main (String[] args)
    {
        try {
            // Do some stuff
            // if Error
            MyCustomKotlinException e = new MyCustomKotlinException("Error Message");
            throw e;
        } catch (MyCustomKotlinException e) {  // <-- THIS PART IS NEVER REACHED
            // Handle Exception
        } catch (Throwable e) {
            e.printStackTrace(); <-- This is catched
        } finally {
            // Finally ...
        }
    }
}

So can anyone explain to me why the exception is not catch. MyCustomKotlinException is inheriting from Kotlins RuntimeException, which is just an alias to java.lang.RuntimeException.

// MyCustomKotlinException.kt
package foo

class MyCustomKotlinException(err: String) : RuntimeException(err)

Update:
I split the throw part into 2 lines (instance creation and throwing) and found that the problem is not the throwing. The try block is left after the instance creation. Is anything wrong with my instance creation of this Kotlin class?

Update2:
I added a second catch block with Throwable and the following Throwable is caught.

java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
...
Caused by: java.lang.ClassNotFoundException: kotlin.jvm.internal.Intrinsics

Update3:
Changed the title to correct error and fixed problem with adding all project files to jar (see answer below). Adding the Kotlin runtime lib to gradle does not work for me.

This error is likely due to the fact that the simple jar task doesn’t take all its runtime dependencies.

From gradle documentation, In your build.gradle.kts you can either create a "fatJar" task or add that to your jar task:

tasks.withType<Jar> {
    // Otherwise you'll get a "No main manifest attribute" error
    manifest {
        attributes["Main-Class"] = "com.example.MainKt"
    }

    // To add all of the dependencies
    from(sourceSets.main.get().output)

    dependsOn(configurations.runtimeClasspath)
    from({
        configurations.runtimeClasspath.get().filter { it.name.endsWith("jar") }.map { zipTree(it) }
    })
}

Thanks for the comment. Indeed compile is deprecated. However the accepted answer does not work with implementation. So I looked up the java library plugin configuration and implementation depends on compileClasspath.

So my solution for now is to add

jar {
    manifest {
        attributes ...
    }
    // This line of code recursively collects and copies all of a project's files
    // and adds them to the JAR itself. One can extend this task, to skip certain
    // files or particular types at will
    from { configurations.compileClasspath.collect { it.isDirectory() ? it : zipTree(it) } }
}

with 

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.50"
    //...
}

I feel like this should be done by the org.jetbrains.kotlin.jvm plugin.

Using compile instead of implementation in the dependencies of the build.gradle file solved it for me.

Had the same problem, compiling my project with Ant in console. I've edded kotlin-stdlib.jar into classpath and problem has gone.

Adding the following solved the issue for me:

dependencies {
    "kotlinCompilerClasspath"(fileTree("libs/gradle-plugins/kotlin"))
}

Here is the content of libs/gradle-plugins/kotlin:

The complete gradle.build.kts (offline setup):

buildscript {
    dependencies {
        classpath(fileTree("libs/gradle-plugins/kotlin"))
    }
}

plugins {
    java
    `java-library`
}

apply(plugin = "kotlin")

version = "2019.06.1"

tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
    kotlinOptions.jvmTarget = "12"
}

repositories {
    flatDir {
        dirs("libs/compile")
        dirs("libs/provided")
    }
}

dependencies {
    "kotlinCompilerClasspath"(fileTree("libs/gradle-plugins/kotlin"))

    api(":kotlin-stdlib-jdk8-1.3.40")
    api(":gson-2.8.5")
}

In my case, a enableFeaturePreview in the settings.gradle caused this issue when migrating to Kotlin 1.3.
