java.lang.NoClassDefFoundError in ubuntu terminal

I am crating a cron scheduler for which i am using the following code:- 

import org.quartz.CronScheduleBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.ScheduleBuilder;

public class CronSched {

public static void main(String[] args) throws SchedulerException {
    System.out.println("Started");
    JobDetail job = JobBuilder.newJob(CronJob.class).build();
    Trigger t1 = TriggerBuilder.newTrigger().withIdentity("MAILER").withSchedule(CronScheduleBuilder.cronSchedule("0 33 2 1/1 * ? *")).build();
    Scheduler sc = StdSchedulerFactory.getDefaultScheduler();

    sc.start();
    sc.scheduleJob(job,t1);
  }

}

and I am compiling teh following code in terminal with the following statement:- 

javac -cp ".:/home/aditya/CronSched/lib/quartz-2.2.3.jar: /home/aditya/CronSched/lib/slf4j-api-1.7.25.jar: /home/aditya/CronSched/lib/slf4j-simple-1.7.25.jar: " CronSched.java

and on running the code I am using the following statement:- 

java CronSched

and I am getting the following error:-
