Java PersistenceException if executed as jar

Question

I'm currently building a Discord Bot with JDA and I'm trying to add a Database Connection with Hibernate. If I execute the Program inside IntelliJ it works without any errors. But after I compiled the Project and execute the jar file, I get this error: (My goal is to execute the bot in a docker container.)

I already checked the jar file for the javax.persistence dependency and the persistence.xml file. They are both provided in the Jar.

My source code is on GitHub. (add_jpa branch)

Does this answer your question? [Could not build ClassFile - ArchiveException](https://stackoverflow.com/questions/27202939/could-not-build-classfile-archiveexception) — XtremeBaumer, Mar 22 '23 at 11:52
@XtremeBaumer thanks, but I already tried to change the java versions but that didn't worked. — YesterDavid135, Mar 22 '23 at 13:37
its not about java versions per se. its about javassist dependecy (maybe also tyhmeleaf) — XtremeBaumer, Mar 23 '23 at 07:05

Try to recreate the artifact by going on

File > Project Structure > Artifacts

then delete the current one and create a new one by going on

+ > Jar > From Modules With Dependencies

Add your main class then click OK and Apply. Then to build the artifact go on

File > Build > Build Artifacts > Build

If it doesn't work this way please add a comment/answer to this post
