update gradle at protoc assignment:

artifact = "com.google.protobuf:protoc:3.4.0"

upgrading to 3.7.0 you have errors about repeated items from proto:

  symbol:   method mutableCopy(DoubleList)
  location: class Builder
/Users/davidraleigh/code/geo-grpc/geometry-service-java/build/generated/source/proto/main/java/com/epl/protobuf/GeodeticBufferParams.java:737: error: cannot find symbol
      maxDeviations_ = emptyDoubleList();

maybe fixed at 3.7.0-rc1:
