Eclipse: Cannot use Hibernate tool plugin to generate cfg xml - eclipse

Question

I followed the spring tutorial for building a restful executable jar. http://spring.io/guides/gs/rest-service/
I am using Eclipse, and I am configuring Hibernate for the first time. I understand that the hibernate cfg xml files can be generated by an eclipse hibernate configuration plugin (as per http://www.mkyong.com/hibernate/how-to-generate-code-with-hibernate-tools/). I have installed that, and configured the connection to my database.
When I attempt to refresh the database view to see the child objects, I get the error:
An internal error occurred during: "Fetching children of Database".
org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
My POM is pretty simple.

I understand this problem can be caused by a dependency loading LocationAwareLogger that is conflicting with Hibernate when it runs to fetch the db children.
I have traced the parent poms back to spring-boot-dependencies https://github.com/spring-projects/spring-boot/blob/master/spring-boot-dependencies/pom.xml where I found slf4j loading. I guess this is the problem.
I am getting out of my depth here. How can I accomplish my aim of configuring the Hibernate eclipse plugin to generate my cfg.xml files? Is there a way to exclude the slf4j that's loading in the grandparent pom?
Thanks

Answer 2

I also happened to have the same problem and I had to exclude all the sl4j jars from the POM as mentioned above. Important thing is to restart the Eclipse after that.

Answer 3

Remove all the slf4j configuration on the artifacts.xml of the eclipse. Then restart the eclipse and redo the hibernate tool process.

Answer 4

A solution that avoids to modify the behaviour of your Project, so modifing only the Hibernare Tools plugin, is to edit the configuration of hibernate in your project:
Go to Classpath panel
Remove Project Entry classpath
Add External JARs libs of the hibernate tool plugin in the folder: eclipse\plugins\org.hibernate.eclipse.libs_3.7.1.Final-v20140303-0022-B124\lib\hibernate
comment temporarely in the pom.xml the block of library of logging SLF4J.
Restart Eclipse
After the use of the tools, restore pom.xml.
