All of a sudden, my code to insert users into a database table using hibernate stopped working (and it had been working for a long time without error). The exception I get says that it cannot create the persistence unit: here is the stack trace shown below:
**-----------------------------------------------------------------------------
javax.persistence.PersistenceException: [PersistenceUnit: craiglistPU] Unable to build Hibernate SessionFactory

**-----------------------------------------------------------------------------
The root exception occurs in this file, on the line inside the 'if' statement:
public class JPAUtil {
//name of persistence unit from persistence.xml
private static final String PERSISTENCE_UNIT_NAME = "craiglistPU";
private static EntityManagerFactory factory;
public static EntityManagerFactory getEntityManagerFactory() {
if (factory == null) {
//line below this throws exception
factory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME);
//line above this
}
return factory;
}
**-------------------------------------------------------------------------------------------------------- Here is a screenshot of my datasource setup, which pings/connects correctly: working datasource setup
Finally, here is the code for my persistence.xml:
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence

version="2.1">
<persistence-unit name="craiglistPU" transaction-type="RESOURCE_LOCAL">

<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<properties>

<property name="hibernate.show_sql" value="true" />
<property name="hibernate.hbm2ddl.auto" value="update" />
</properties>
</persistence-unit>
I would assume that my bean/model classes are correctly configured; I used eclipse jpa to create them and haven't modified them since creation.
Any ideas on how to fix this issue would be greatly appreciated. Also, if you would like to see any more source code, let me know and I can provide it (or allow you access to my repository). Thanks so much!
EDIT After examining the cause of the stack trace:

I now believe this is caused by javax.validation and hibernate-validator issues. My pom includes the following dependencies:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.0.2.Final</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-validator-annotation-processor -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator-annotation-processor</artifactId>
<version>6.0.2.Final</version>
</dependency>
<!-- https://mvnrepository.com/artifact/javax.validation/validation-api -->
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.0.Final</version>
</dependency>
Any ideas if I need to exclude anything from these dependencies, or choose different version numbers so they work correctly together? Thanks.
