my quickly hand-made command line to detect multiple versions of the same dependency :

mvn dependency:tree | grep ":compile" | sed 's/.* \(.*\):compile/\1/' | sort -u | cut -d ':' -f '1 2' | uniq -c | grep -vE "^ *1"

then, we can use the following command line to get used versions of theses dependencies (it isn't an optimized command line ;) : 

for dep in $(mvn dependency:tree | grep ":compile" | sed 's/.* \(.*\):compile/\1/' | sort -u | cut -d ':' -f '1 2' | uniq -c | grep -vE "^ *1" | cut -d ' ' -f 8); 
do 
  echo $dep; 
  mvn dependency:tree | grep $dep; 
  echo 
done
