Errors when trying to install mapdb

When I try to install MapDB, by adding it to adding.cfg, it doesn’t install but the logging shows me the next error:

2019-07-25 16:53:40.824 [ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing ‘openhab-binding-mapdb’: Error restarting bundles:
Could not resolve module: org.openhab.binding.modbus [232]
Another singleton bundle selected: osgi.identity; type=“osgi.bundle”; version:Version=“”; osgi.identity=“org.openhab.binding.modbus”; singleton:=“true”

I’m running OH2.4.1 on a RaspberryPi (using openhabian)

Does anybody have an idea what can cause the error?
