             Project: Cassandra
          Issue Type: Bug
            Reporter: Michael Hornung

Hallo,

with my application I have a AKKA-http microservice which want’s to acess a 
cassandra database table from scala.
Therefore I included this dependency in SBT:
         "com.datastax.cassandra" % "cassandra-driver-core"       % "3.2.0"
In my scalafile I have this coding:
--------------------------------------------------------------------------
….
import com.datastax.driver.core.Cluster
import com.google.common.util.concurrent._
….
    val cassandraHost    = "localhost"
    val keyStore         = "data4service"
    //setup cassandra
    val cluster = {
                    Cluster.builder()
                      .addContactPoint(cassandraHost)
                      .withCredentials("user", "password")
                      .build()
                  }
    //connect to cassandra keystore
    val session = cluster.connect(keyStore)
    val product = "123e4567-e89b-12d3-a456-426655440003"
    val select = s"SELECT quantity FROM stock WHERE product = $product"
    val result = session.execute(select)   
….

During build guava Version 19.0 is downloaded automatically

Unfortunately if I run my application I get this Error during runtime: 
--------------------------------------------------------------------------
com.datastax.driver.core.exceptions.DriverInternalError: Detected incompatible 
version of Guava in the classpath. You need 16.0.1 or higher.
        at 
com.datastax.driver.core.GuavaCompatibility.selectImplementation(GuavaCompatibility.java:138)
        at 
com.datastax.driver.core.GuavaCompatibility.<clinit>(GuavaCompatibility.java:52)
--------------------------------------------------------------------------

that is not logical bevause Guava 19.0 is on the system. Can you help me?

Kind regards,
Michael
