The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory   Please see the error below    Caused by  java sql SQLException  Access denied for user     localhost   using password  NO     which points to username not getting populated   Please recheck system properties   dataSource setUsername System getProperty  root       some packages seems to be missing as well pointing to a dependency issue   package org gjt mm mysql does not exist   Please run a mvn dependency tree command to check for dependencies
