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

Question

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 i

Answer 1

You need to configure your project with kotlin. So in Android Studio:

1. click on Tools => kotlin => Configure kotlin in project

2. Then in dialog check : All module containing kotlin files

3. and select version

4. press ok

Done.

Answer 2

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

Answer 3

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.

Answer 4

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) }
    })
}

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"))
    compileOnly(":javaee-api-8.0")
    api(":kotlin-stdlib-common-1.3.40")
    api(":kotlin-stdlib-1.3.40")
    api(":kotlin-stdlib-jdk7-1.3.40")
    api(":kotlin-stdlib-jdk8-1.3.40")
    api(":gson-2.8.5")
}

Answer 6

Adding all project files to the jar fixed the problem for me. I added the following line to my build.gradle

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) } }
}

Update: Changed configurations.compile.collect to configurations.compileClasspath.collect according to this answer below.
