Caused by: javax.persistence.PersistenceException: Unable to build entity manager factory

Hi Ninja Community,

I'm testing steps here: http://www.ninjaframework.org/documentation/working_with_relational_dbs/jpa.html
Created a new project from documentation and tried to run jar file as a standalone app, the same guidance from doc. java -Dninja.port=9000 -jar MY-APPLICATION.jar

Getting this error, also from the document I see information if it's related to the error or not don't know.

Please be aware that since Ninja 6.4.3, alongside with Jetty 9.4.12, the dependency allowing Jetty servlets annotations (that should not be useful for your Ninja Framework project) have been excluded from the stack. This was caused by an incompatibility between the version of the java bytecode handler ASM used by this module (6.2) and the java bytecode handler javassist used by Hibernate.

[SOLVED]
updating maven-shade-plugin from 2.2 -> 3.2.x solved the above issue.

Same issue here with OpenJDK8 and Ninja 6.8.1. I have to upgrade Hibernate dependencies to 5.6.3.Final too. Now the single shaded jar working well.

It may be time to update these outdated dependencies.

DEPENDENCY	CURRENT VERSION	LATEST_VERSION
hibernate-entitymanager	4.3.8.Final (Jan, 2015)	5.6.3.Final (Dec, 2021)
hibernate-c3p0	4.3.8.Final (Jan, 2015)	5.6.3.Final (Dec, 2021)
maven-shade-plugin	3.2.1 (Nov, 2018)	3.2.4 (Jun, 2020)

I totally agree why are we still using such an old version of hibernate ? It is not even compatible with mysql 8 server with is the default mysql server version of most linux servers.

We can't use org.hibernate.dialect.MySQL8Dialect in this version
