I’m trying to use a local snapshot jar as a dependency but I get the following error:

FAILURE: Classpath entry /<snip>/finagle/finagle-zipkin-kafka/target/scala-2.11/finagle-zipkin-kafka_2.11-6.35.0-SNAPSHOT.jar for target 3rdparty/jvm/com/twitter:finagle-zipkin-kafka is located outside the working directory “/<snip>/quizup-monorepo/.pants.d”.

This is in my BUILD file:

jar_library(name='finagle-zipkin-kafka',
  jars = [
    jar(org='com.twitter', name='finagle-zipkin-kafka', rev='6.35.0-SNAPSHOT',
      url='file:///<snip>/finagle/finagle-zipkin-kafka/target/scala-2.11/finagle-zipkin-kafka_2.11-6.35.0-SNAPSHOT.jar',
      mutable=True),
  ],
)

This approach is suggested in https://pantsbuild.github.io/3rdparty_jvm.html. Do you know what might be wrong here?
