I’m experiencing an unexpected shut down with jqassistant 2.4.0. Neo4J is provoking a fatal exception. Interestingly with jqassistant 2.0.10 I’m not experiencing this problem.

I have an application where I’m trying to implement jqassistant checks. This is the error I’m getting:

[ERROR] Failed to execute goal com.buschmais.jqassistant:jqassistant-maven-plugin:2.4.0:analyze (default-cli) on project myapp-backend: Execution def

I do not think I need Neo4J unless it’s something needed for jqassistant to work. Is there a way to remove this dependency?

How can I make jqassistant run with version 2.4.0 and avoid the Neo4J DB shutdown related to target store format ‘AF4.3.0’?
