I just had the same error today, from the master (Ubuntu 16.04, maven 3.3.9, jdk 1.8.0_131) :
[ERROR] Failed to execute goal on project graphhopper-map-matching-core: Could not resolve dependencies for project com.graphhopper:graphhopper-map-matching-core:jar:0.9-SNAPSHOT: Could not find artifact com.graphhopper:graphhopper-reader-osm:jar:0.9-SNAPSHOT -> [Help 1]

<name>GraphHopper Map Matching</name>"):
I know it's dirty, but it seems to work, if it can help someone else waiting for the merge with the main graphhopper
