kotlinlang

Hi <@U0MDBPRQB> I was preparing a message about it. Just a few seconds! :pray:

<https://kotlinlang.slack.com/archives/C5UPMM0A0/p1599034386118600>

Please <@U0MDBPRQB>, let us know when it's already working for you after adding that repository

Thank you, Rachel! Unfortunately it still does not work. New error message: Execution failed for task ‘:kaptKotlin’.
&gt; A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
   &gt; java.lang.reflect.InvocationTargetException (no error message)

Please, can you share the repository or something to reproduce the error?

Gradle configuration and the piece of source code

Sure. Gradle build file:
```plugins {
    java
    kotlin("jvm") version "1.4.0"
    kotlin("kapt") version "1.4.0"
}

group = "org.example"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
    jcenter()
    maven(url = "<https://artifactory.riedel.net/artifactory/mediornet-rumba/>")
    maven(url = "<https://kotlin.bintray.com/kotlinx>")
    maven(url = "<https://jitpack.io>")
    maven("<https://dl.bintray.com/arrow-kt/arrow-kt/>")
    maven("<https://oss.jfrog.org/artifactory/oss-snapshot-local/>")
}

val arrow_version = "0.11.0-SNAPSHOT"
dependencies {
    implementation(kotlin("stdlib"))
    implementation("io.arrow-kt:arrow-optics:$arrow_version")
    implementation("io.arrow-kt:arrow-syntax:$arrow_version")
    kapt("io.arrow-kt:arrow-meta:$arrow_version")
}```
Source file:
```import arrow.optics.optics

@optics
data class Inner(val i: Int) {
    companion object
}
@optics
data class Outer(val s: String, val inner: Inner) {
    companion object
}

fun main() {
    val d = Outer("bla", Inner(0))
}```


<@U0MDBPRQB>, please, add a `package` to the source code and try it again

Rachel you’re the best! That did the trick.

Thank you so much for letting us know and for trying it :tada:
