# assume you have a java application named update/*.jar that is using jars in update/lib/.jar
# this script will unpack all jars into the run folder
# then start your application inside the run folder with very simple classpath options

sdir=`dirname $(readlink -f $0)`
rootdir=`dirname $sdir`
echo rootdir $rootdir

# Remove the old run dir, recreate it
rm -rf $rootdir/run > /dev/null
mkdir -p $rootdir/run
cd $rootdir/run

# Unpack all jars into run
for z in $rootdir/update/*.jar; do echo $z ; unzip -oq $z; done
for z in $rootdir/update/lib/*.jar; do
    # do not override update/*.jar with update/lib/*jar content
    if [ ! -e $rootdir/update/`basename $z` ] ; then
        echo $z ; unzip -oq $z

# Run your main class
