--warning option don't exist on all versions of tar

[REBELinBLUE]

Reported via Email

OS X and BSD's tar command doesn't have the --warning=no-timestamp option used at https://github.com/REBELinBLUE/deployer/blob/master/resources/scripts/deploy/steps/CreateNewRelease.sh#L18

Something like the following may help

if [ "$(uname -s)" = 'Linux' ]; then
   tar --warning=no-timestamp --gunzip --verbose --extract --file={{
remote_archive }} --directory={{ release_path }}
else

   # BSD: pkg install gtar / OSX: brew install gnu-tar
   # gtar --warning=no-timestamp --gunzip --verbose --extract
--file={{ remote_archive }} --directory={{ release_path }}

   tar --gunzip --verbose --extract --file={{ remote_archive }}
--directory={{ release_path }}
