Imported NED type not found: 'inet.networklayer.common.InterfaceEntry'

[000407]

I am trying to import simulte 1.2.0 into my OMNeT++ workspace, into which I already have inet4.4 installed(during the startup of the IDE). But I am unable to build the imported simulte, with an error Imported NED type not found: 'inet.networklayer.common.InterfaceEntry' (see the attached below).

apps/alert/AlertReceiver.cc
apps/alert/AlertReceiver.cc:38:13: error: unknown type name 'InterfaceEntry'
            InterfaceEntry *ie = ift->findInterfaceByName(multicastInterface);

Looks like a compatibility issue. Downgraded OMNeT++ to 5.6.2, INET to 4.2.x. Seems SimuLTE 1.2.0 works okay with this combination.
