No persistence provider for entitymanager named xyz

I have a JavaFX Maven project in IntelliJ, which uses Hibernate. When the app is starting, I am getting the following error message:
No persistence provider for entitymanager named xyz
Why? My META-INF/persistence.xml is located in myproject/src/main/resources (the directory is checked as resource folder in project settings).
I am sure I've downloaded all Hibernate JARs via Maven.
My persistence.xml is correct:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="xyz">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>entity.User</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLiteDialect"/>
<property name="javax.persistence.jdbc.url" value="jdbc:sqlite:java.sqlite"/>
<property name="javax.persistence.jdbc.driver_class" value="oracle.jdbc.driver"/>
<property name="hibernate.hbm2ddl.auto" value="none"/>
<property name="hibernate.show_sql" value="false"/>
<property name="javax.persistence.schema-generation.database.action" value="create"/>
</properties>
</persistence-unit>
</persistence>
Java code:
factory = Persistence.createEntityManagerFactory("xyz");
In my an old non-Maven project the code above worked fine.

your persistence.xml must be located in the META-INF folder

There was a different context and solution in my case:
Context:
see the log below:

Caused by: javax.persistence.PersistenceException: No Persistence provider for EntityManager named NewPersistenceUnit`
Solution:
As its clear from logs above, persistenceUnit has been found and some data like dialect, username and password is extracted.
There was problem in mapping of entities. By commenting out #Entity one by one on entities, I was able to find the problem and solve it, without any change in persistence.xml file.
I have no idea why error like No Persistence provider for EntityManager named X should be shown when there is a problem in entity mapping!

Hibernate ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml] IntelliJ

I have a problem with my hibernate.cfg.xml in IntelliJ IDE.
Here is my hibernate config file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver:class">org.postgresql.Driver</property>
<property name="connection.url">jdbc:postgresql://localhost/HIndex</property>
<property name="hibernate.connection.username">index_user</property>
<property name="hibernate.connection.password">password</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL Dialect -->
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQL82Dialect</property>
<!-- Assume test is the database name -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>
<!-- Names the annotated entity class -->
<mapping class="HIndexSaar.HIndex.Person"/>
<mapping class="HIndexSaar.HIndex.University"/>
<mapping class="HIndexSaar.HIndex.Publication"/>
</session-factory>
</hibernate-configuration>
And this is my application class:
package HIndexSaar.HIndex;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class HibernateManager {
private static SessionFactory factory;
public HibernateManager(){
//
//* Setup the configuration.
//
Configuration config = new Configuration().configure("hibernate.cfg.xml").addAnnotatedClass(Person.class) .addAnnotatedClass(University.class).addAnnotatedClass(Publication.class);
factory = config.buildSessionFactory();
}
I get an error by running the following code:
package HIndexSaar.HIndex;
public class AppHibernate {
public static void main(String[] args){
HibernateManager mng = new HibernateManager();
[...]
}
}
So something seems to be broken in building the SessionFactory in the HibernateManager. I get the error
Could not locate cfg.xml resource
and the following stacktrace:

I already have placed the hibernate.cfg.xml file under /src/main/java/resources but obviously something goes still wrong.
Does somebody have an idea what could be the mistake I made? Surprisingly, the same code runs in Eclipse without error, so what could be the problem of IntelliJ? I use the same SDK/JDK, namely jdk 1.7.

If your are using intellij then try to create new module with hibernate framework support then paste this same code and execute it.
This might be path difference in clipse and intellij

I have followed intellij instruction but i can not find any solution. Please help

It is not an error. It is just an information that you don't have hibernate.properties file in the class path. You have properties in the hibernate.cfg.xml, it is ok too. But you need to specify hibernate.dialect, hibernate.connection.username and hibernate.connection.password.
And if you don't have tables in the database you need this too
<property name="hbm2ddl.auto">update</property>

Where persistence.xml should be?

I'm trying to figure out why my Java program returns me "No persistence provider for EntityManager name WroProjectPU"
I'm thinking it's happening because Java can't find persistence.xml file.
I tried to use different configurations, but no one worked.
Currently, the structure of my program is looking like this:
where selected Main.java file is the file, where I have
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("WroProjectPU");
The main folder WroProject is under this absolute location:
C:\Users\Szymon\workspace\WroProject
Could you tell me where I should put my persistence.xml file? The full absolute path please.
Thanks in advance!
AFTER EDIT:
My persistence.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" 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 http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

I believe it is an issue with this line in your xml configuration.
