No Persistence provider for EntityManager Error

Question

I am getting this error "No Persistence provider for EntityManager named" and not able to proceed. I am learning hibernate and trying so hands on stuff. I tried all the methods mentions in this search forum, but still i get the same error. I tried the following

1. SAVED THE persistent.xml file in src/main/resources/META-INF/persistent.xml.
2. Updated the provider to "org.hibernate.jpa.HibernatePersistenceProvider".

Still no luck, can any one kindly help in how to resolve this. Below is screen shot and code.

You need to change the maven dependency version from <version>6.1.0.Final</version> to <version>5.2.11.Final</version> for <artifactId>hibernate-core</artifactId> as there has been significant changes from Hibernate 5 to 6 and need to consider upgrading corresponding dependencies and schema names etc in persistance.xml file

You can read another thread here - why is dependency to javax.persistence-api removed in hibernate-core 6.0.2

When I tried with 6.1.0.Final - I also get the same error as mentioned below.

But when I changed version back to 5.2.11 then it connected to database.

PS : I've used the maria db instead of mysql but that should not matter.
