Method threw 'java.lang.NoClassDefFoundError' exception. DeviceInfoProtos$Device$Builder.toString()

[Ruchika Gupta]

Hi there, 

I am getting this exception while creating the object of probuff generated class.  

I am using java1.8 and protobuf library 3.12.2.  

 'java.lang.NoClassDefFoundError' exception. DeviceInfoProtos$Device$Builder.toString()

Can you please help me on this?  Let me know if you need more details.  

Sample Schema. 

syntax = "proto3";
import "Telemetry.proto";
import "System.proto";
import "Command.proto";
import "Connectivity.proto";

package com.syncup.tmo.petbindecoder.firmware;

option java_package = "com.syncup.firmware";
option java_outer_classname = "DeviceInfoProtos";

// This is the packet that would be send/receive on both end
message Device{
  
   System system = 1;
   Telemetry telemetry = 2;
   repeated Command commands = 3; // last received commands
   Connectivity connectivity = 4; // available wireless connectivity and current wireless bearer
  
}

Thanks 

Ruchika
