java.lang.NoSuchFieldError: name at run time in hibernate project

Trying my hand at my first hibernate (JPA annotations) console application. And I've been running around in circles trying to sort out dependencies, it feels like I'm trying to build a house of cards in a hurricane. Also, I'm using maven, I was under the impression that that maven is supposed to prevent this type of thing.. Anyways this is the error that I'm getting:

Exception in thread "main" java.lang.NoSuchFieldError: name
    at org.slf4j.impl.Log4jLoggerAdapter.<init>(Log4jLoggerAdapter.java:75)
    at org.slf4j.impl.Log4jLoggerFactory.getLogger(Log4jLoggerFactory.java:75)
    at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:103)

And this is my pom file:

    }

    public Integer getId() {

        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;

    @Override

    }

    @Override
    public String toString() {
        return "com.deangrobler.hibernatetest.User[ id=" + id + " ]";
    }

}

If I can get some help on this I shall be eternally grateful!

You have two different version dependency for hibernate entity-manager. This will not work. Remove one of them

<dependency>
      <groupId>hibernate</groupId>
      <artifactId>hibernate-entitymanager</artifactId>
      <version>3.4.0.GA</version>
      <exclusions>
        <exclusion>
          <artifactId>ejb3-persistence</artifactId>
          <groupId>org.hibernate</groupId>
        </exclusion>
      </exclusions>
    </dependency>
........................

<dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-entitymanager</artifactId>
      <version>3.6.10.Final</version>
    </dependency>

try either deleting your slfj dependency entry in your pom, your force the hibernate dependency to exclude it. Hibernate wants to use its own.

 <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-annotations</artifactId>
    <version>3.6.10.FINAL</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
    </exclusions>
    <scope>compile</scope>
</dependency>

etc. Add the same exclusions for hibernate-core etc.

Seems to be a version conflict in the dependencies for artifact slf4j-log4j12.

You could check the output of "mvn dependency:tree" to check for a conflict.
