A modern programming language that makes developers happier.

kotlinlang

I cloned the kotlin repo for the first time today and followed the instructions. But now on executing any gradle build task, I get a lot of exceptions, like: ``` e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class kotlin.jvm.internal.FunctionBase, unresolved supertypes: Serializable
    class kotlin.jvm.internal.CallableReference, unresolved supertypes: Object, Serializable
    class kotlin.jvm.internal.Reflection, unresolved supertypes: Object
    class kotlin.jvm.KotlinReflectionNotSupportedError, unresolved supertypes: Error

JvmClassMapping.kt: (25, 8): Unresolved reference: java``` Am I doing something wrong, or is this related to the “build failure” badge on github?
