SessionFactory creation failed.java.lang.NoClassDefFoundError

While practicing the Hibernate auto increment example, I have faced lots of issues. In that one of the thing is SessionFactory creation error. Error stack trace is as follows,

Here is the HibernateUtil class which I have tried creating the SessionFactory instance.

package com.jtb.util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {

 private static SessionFactory sessionFactory = null;

 private static synchronized SessionFactory buildSessionFactory() {
  try {
   return new AnnotationConfiguration().buildSessionFactory();
  } catch (Throwable ex) {
   System.err.println("SessionFactory creation failed." + ex);
   throw new ExceptionInInitializerError(ex);
  }
 }

 public static SessionFactory getSessionFactory() {
  return buildSessionFactory();
 }

 public static void shutdown() {
  getSessionFactory().close();
 }

}

Solution:
To solve the problem, you need to include the commons-logging.jar file into your project classpath or add the dependency to your pom.xml if you are using maven.

<!-- https://mvnrepository.com/artifact/commons-logging/commons-logging -->
<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.2</version>
</dependency>

Add the below lines into your build.gradle if you are Gradle build tool.

// https://mvnrepository.com/artifact/commons-logging/commons-logging
compile group: 'commons-logging', name: 'commons-logging', version: '1.2'
