hello! i'm trying to upgrade from

com.google.protobuf

version

2.6.1

to version

3.1.0

it builds fine, but at runtime, i get a

NoSuchMethodError

it looks like it's a classpath issue (we use Spark/Hadoop, and that uses a different version of protobuf) we already shade

com.google.protobuf

, and i've tried excluding

com.google.protobuf

from the JVM binary the Ivy dependency report doesn't complain about evictions either i think Spark/Hadoop's protobuf version must be getting picked up on the classpath any ideas on what to try next?
