Pushの前にかならずテストするGitのHookスクリプト

GradleとMavenのプロジェクトに使えます。

Gradleの場合、gradlewrapperを使います。

#!/bin/bash

echo "prepush called"

DIR=$PWD
ROOT=$PWD/`git rev-parse --show-cdup`
ROOT=${ROOT%/}
result=0

#dryRun
function dryRun(){
  local result=0
  pushMessage=`git push --dry-run --no-verify 2>&1`
  result=$?

  if [ $result -eq 0 ]; then
    if echo $pushMessage | grep -e "^Everything.\+" > /dev/null 2>&1; then
      result=1
    fi
  else
    if echo $pushMessage | grep -e "has no upstream branch" > /dev/null 2>&1; then
      result=0
    fi
  fi

  if [ $result -ne 0 ]; then
    echo $pushMessage 1>&2
  fi
  return $result
}

# status check
function isReadyToPush(){
  local _test=`git submodule foreach "git status|grep 'nothing to commit, working directory clean'"`
  local _expect=`git submodule foreach "git status|echo 'nothing to commit, working directory clean'"`
  if [ "$_test" != "$_expect" ] ; then
    echo "[error] submodule has uncommitted changes." 1>&2
    return 1

  _expect=`git submodule foreach "git reflog -1|grep 'HEAD@{0}'|sed -e 's/ HEAD.\+//g'"`
  if [ "$_test" != "$_expect" ] ; then
    echo "[warn] submodule has unpushed or unpulled changes." 1>&2
    return 0
  fi
  return 0
}

    chmod +x ./gradlew
    ./gradlew clean test 2>&1 >/dev/null;result=$?
    cd $DIR
    return 0

  return 1
}

    mvn clean test 2>&1 >/dev/null;result=$?
