"Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory" is that class in your classpath? — Federico klez Culloca, Apr 04 '23 at 10:31
@GermanK no, but some of the code you import (jgit, from the looks of that stack trace) may depend on that. — Federico klez Culloca, Apr 04 '23 at 10:35
Ok, but you need to include in the classpath its dependencies as well. — Federico klez Culloca, Apr 04 '23 at 10:41

Don't use system scope, let maven do its job and download what you need. — tgdavies, Apr 04 '23 at 10:45
