[osmosis-dev] An OsmosisRuntimeException : A question of un-named argument...

[michel.souweine at free.fr]

Hello
Although I watched pretty thoroughly the osmosis-dev archives from 2010 to now, I couldn't find any answer, but maybe I was shortsighted, for the depressing message I got on attempting to run my java sdk project  
Here is the message : 
org.openstreetmap.osmosis.core.OsmosisRuntimeException: Only one default (un-named) argument can exist per task

I carefully used "latest" versions for both MATSIM and OSMOSIS with Eclipse as advised...

I would be grateful for any  help or hint and thank you deeply in advance
