which does check for the existence of Maven by way if

else
   if [[ ! -f $MAVEN ]]; then 
      echo "Apache Maven not installed"

but that check is from the results of a IF ... THEN ... ELSE. and only executed if ELSE.

Can we not issue the check for maven existence above and before the IF ... THEN ... ELSE
