A pre-push git hook which runs a gradle test task

pre-push

#!/bin/sh
# this hook is in SCM so that it can be shared
# to install it, create a symbolic link in the projects .git/hooks folder
#
#       i.e. - from the .git/hooks directory, run
#               $ ln -s ../../git-hooks/pre-commit.sh pre-commit
#
# to skip the tests, run with the --no-verify argument
#       i.e. - $ 'git commit --no-verify'

set -e

# stash any unstaged changes
git stash save "prePush" -q --keep-index

# unstash the unstashed changes (if any) on exit or interrupt
function unstash {
	git stash apply stash^{/prePush} -q || true
}

trap unstash EXIT

# run the tests with the gradle wrapper
./gradlew test -q

How does that unstash function work?

When I try to run it, git says that stash^{/prePush} is not a stash reference even though git stash list | grep prePush shows that one exists.

[edit: Nevermind... The reason mine doesn't work is because I'm using git stash pop instead of git stash apply. When I use "apply" it understands the search string.]
