I am using jQA after some time again. My scenario is a Multi-Module Maven project. After successful scans of some modules jQA fails with the following exception on one modules:

[ERROR] Failed to execute goal com.buschmais.jqassistant:jqassistant-maven-plugin:1.6.0:scan (default) on project mock-kundenkonto: Execution default of goal com.buschmais.jqassistant:jqassistant-maven-plugin:1.6.0:scan failed: Error starting org.neo4j.kernel.impl.factory.GraphDatabaseFacadeFactory, <<someDir>>/store: Component 'org.neo4j.kernel.internal.locker.StoreLockerLifecycleAdapter@653a590c' was successfully initialized, but failed to start. Please see the attached cause exception "Unable to obtain lock on store lock file: <<someDir>>/store/store_lock. Please ensure no other process is using this database, and that the directory is writable (required even for read-only access)". -> [Help 1]

The problem is reproducible with version 1.7.0.M3 and it does not matter which Maven version is used (I tried 3.5.2 and 3.6.0) and recent Java versions (OpenJDK 1.8 build 192 and Zulu OpenJDK 8.0.202) both on Win 10 and OS X 10.14.

The error was produced with

Apache Maven 3.6.0 (97c98ec64a1fdfee7767ce5ffb20918da4f719f3; 2018-10-24T20:41:47+02:00)
