    The issue that the pull request is fixing is the version comparison part. 
The ant version extraction is working like charm and doesn't need to be changed.
    
    @jeking3, you are not testing accurately. Thats not a bash script file, 
this is a Autoconf/m4 macro and the following:
    `ant -version | sed -n 's/.*version \(@<:@0-9\.@:>@*\).*/\1/p'`
     at the time of running the bash command will have the 'Quadrigraphs'(@<:@) 
escaped:
    `ant -version | sed -n 's/.*version \([0-9\.]*\).*/\1/p'`
    
    For further details check the docs: 
    https://www.gnu.org/software/autoconf/manual/autoconf.html#Quadrigraphs
    
    I hope this clears the things a bit.
    Thanks
