Hello! I replaced 3.4.2 with 3.8.9 and I get the exception:
It is hard to tell exactly what the issue is without the pom.xml and complete logs. It sounds like it could be an issue where this version (3.8.9) may not have the libs it needs in relation to its installation documented here.
If that doesn’t solve the issue, please post pom, command used to run the maven goal (please set logLevel=debug), and complete log.
