Hi everyone, I have issues creating a library fat jar for my kotlin project. I’m using the built-in jar plugin and adding the compiled dependencies. This is the task:

task fatJar(type: Jar) {
    from {
        // Add runtime dependencies to jar.
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
    with jar
}

Is there something wrong?
When I include the jar into another project I can only see my classes from the Java code, not the Kotlin one.

I'd recommend just using Shadow plugin <https://imperceptiblethoughts.com/shadow/>

I already used it but I had the same issue… My kotlin code bundled into the jar is not visibile from other kotlin sources under the main/kotlin dir, only from main/java

[artem_zin]

are you sure you're compiling Kotlin?

[artem_zin]

might need to add that src folder to srcs

Just edited it like

task fatJar(type: Jar) {
    // Add runtime dependencies to jar.
    from configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    from sourceSets.main.allSource
    with jar
}

, so now also my sources are bundled… But this doesn’t fix

are you sure you’re compiling Kotlin?

I’m building with ./gradlew build fatJar where fatJar is the task name

shadowJar worked for me too

were your library sources into the kotlin dir?
