Using Hibernate with Gradle - no persistence provider for EntityManager named

Im trying to make Hibernate working with my Gradle project, but all I got is Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider

for EntityManager named manago
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:69)
    at jpa.EntityManagerFactory.reinit(EntityManagerFactory.java:69)
    at jpa.EntityManagerFactory.<init>(EntityManagerFactory.java:61)

    at jpa.EntityManagerFactory.getInstance(EntityManagerFactory.java:43)
    at main.Main.main(Main.java:32)

my build.gradle file:

apply plugin: 'application'
apply plugin: 'java'
apply plugin: 'war'
mainClassName = "main.Main"
sourceSets.main.output.resourcesDir = sourceSets.main.output.classesDir
sourceCompatibility = '1.6'
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

if (!hasProperty('mainClass')) {
    ext.mainClass = 'main.Main'
}

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.hibernate', name: 'hibernate-core', version: '3.6.7.Final'

persistence.xml file in /src/META-INF directory:

    </properties>
</persistence-unit>
</persistence>

Main class:

package main;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.Date;
import javax.persistence.Persistence;
import jpa.Routes;
import org.hibernate.Session;


public class Main {
   public static void main(String[] args) {
               EntityManagerFactory emf = Persistence.createEntityManagerFactory("manago");
    }
}

What should I do to finally get it to work?

Add below provider into your persistence.xml and try

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

Your persistence-unit is - rather clearly - named as WebSISMSPUpgsql in your persistence.xml and not manago. Simply change Main.main into 

public static void main(String[] args) {
 EntityManagerFactory emf = \
    Persistence.createEntityManagerFactory("WebSISMSPUpgsql");
}

or change the unit's name in persistence.xml.
