'Intellij and jar file: No Persistence provider for EntityManager named xxx

I use intellij to create a jar package, but it does not work correctly.
After it is created and all the external library jar files are created as well, when I start the program I get the following error.

Mai 13, 2022 4:54:38 NACHM. javax.persistence.spi.PersistenceProviderResolverHolder$DefaultPersistenceProviderResolver log
WARNING: javax.persistence.spi::No valid providers found.
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named xxx

The persistence.xml file is properly configured and is used directly by the program, when it is started on intellij.
The location of the persistence.xml file is in /scr/java/resources/META-INF.
I do not understand whether the location of the file in this case is wrong or you have to change something else

Try placing it here: src/main/resources/META-INF/persistence.xml
