如何通过使用 git 提交号作为 xcode 内部版本号来避免无限循环

Question

我最近使用脚本来增加与 git 提交相关的项目构建号，我遇到了无限循环。

我构建，然后

内部版本号被更改，然后我提交，因为 info.plist 被更改，然后下次我构建时内部版本号将更改，所以我必须再次提交它，因为 info.plist 被更改，然后你知道会发生什么。

有什么方法可以避免这种情况吗？或者有更好的方法来自动增加内部版本号？

PS. 由于我和其他人一起做过这个项目，所以每次构建时手动更改数字或碰撞它都很难保持数字。

是的，这是一个经典的问题。 我使用类似的技术，但我没有将内部版本号与 git 提交相关联，而是检测源代码树中与版本文件(保存版本和内部版本号的简单文件(的修改时间相关的文件更改。 如果有更改，那么我会增加内部版本号。

这是我使用的python脚本。 您应该在 Xcode 项目中将其设置为单独的目标，然后使其他目标依赖于此目标。 它将根据需要使用新版本/内部版本号更新您的.plist文件。 它假定源树位于版本文件的位置下方：

#!/usr/bin/env python
#
# Bump build number in Info.plist files if a source file have changed.
#
# usage: bump_buildnum.py buildnum.ver Info.plist [ ... Info.plist ]
#
# [e-mail], 2014.

我使用的方法是在包含版本号的文件中有一个占位符，然后让构建服务器在本地将该占位符替换为正确的版本号，然后再创建可分发包。存储库中的 info.plist 版本不会更改;它始终具有占位符。

我用纯粹的bash制作了@trojanfoe的答案版本。这假定一个名为versions的文件放置在根项目目录中。

#!/bin/bash
beginswith() { case $2 in "$1"*) true;; *) false;; esac; }
shopt -s dotglob
versionModifiedAt=$(date -r versions +%s)
needsUpdate=false
processEntry() {
  if [[ "$1" == "versions" ]]; then return; fi
  if [[ "$1" == ".git" ]];     then return; fi
  if beginswith ".git/" "$1";  then return; fi
  if [ $(date -r "$1" +%s) -gt "$versionModifiedAt" ]; then
    needsUpdate=true
  fi
}
# Top level
for entry in *; do
  processEntry "$entry"
  if [[ $needsUpdate == true ]]; then
    break;
  fi
done
# Nested
if [[ $needsUpdate != true ]]; then
  for entry in **/*; do
    processEntry "$entry"
    if [[ $needsUpdate == true ]]; then
      break;
    fi
  done
fi
if [[ $needsUpdate != true ]]; then
  echo "No update needed"
  exit 0
fi
echo "Updating version and build info"

buildPlist=${PROJECT_DIR}/${INFOPLIST_FILE}
# Increment build number
buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$buildPlist")
buildNumber=$((0x$buildNumber))
buildNumber=$(($buildNumber + 1))
buildNumber=$(printf "%04X" $buildNumber)
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$buildPlist"
echo -e "${git_release_version#*v}n$buildNumber" > versions
