Kotlin 1.5.10 - slf4j: Exception in thread "main" java.lang.NoSuchMethodError: 'org.apache.log4j.Level org.apache.log4j.Level.toLevel(java.lang.String, org.apache.log4j.Level)'

I would like to add Kotlin with JDBC to the OraBench project. OraBench is supposed to be a benchmark framework for Oracle database drivers.

I have now a problem with logging.I also have to admit that I am not a big expert in Kotlin. It would be great if one of the more experienced colleagues could help me with my problem.

I’m aware of the following topic: https://discuss.kotlinlang.org/t/log4j-and-kotlin-compiler-1-3-11-jar-java-lang-nosuchmethoderror-org-apache-log4j-level-tolevel/11186 but it doesn’t help :thinking:
