基于git更新自动化打包的思路
- 处理git拉取，切换分支
- unity提供打包，打assetbunle接口
- 编写外部打包工具脚本
在流程开始之前需要了解C#和Python的参数传递
1、处理git拉取，切换分支
使用git拉取分支无非就是调用git的命令，在此，python中提供了subprocess库可用来执行shell命令。除了使用subprocess.call()调用git命令，python还提供了gitpython库方便git的使用。因为git操作用到了拉取、切换分支、重置等操作，对于整体打包流程只需知道结果，所以引入operation（操作）的概念，将所有的git操作封装到operation中，python脚本如下：
# file name GitOperation.py
#coding=utf-8
#liyiyuan 2019-05-30
# git upgrade operation
import subprocess
import sys
project_path = sys.argv[1]
branch = sys.argv[2]
def git(cmd):
out_put = subprocess.Popen('git -C {0} {1}'.format(project_path, cmd), shell=True, stdout=subprocess.PIPE).communicate()[0]
return out_put.decode('utf-8')
def update_git(project_path, branch):
# 清空本地分支所有修改
git_info = git('status')
print(git_info)
if 'nothing to commit, working tree clean' not in git_info:
git_info = git('reset --hard')
print(git_info)
git_info = git('clean -df')
print(git_info)
# 获取本地所有分支
# git_info = g.branch()
git_info = git('branch')
print(git_info)
all_branch = git_info.replace(' ', '').split('\n')
currentBranch = '*' + branch
if currentBranch not in all_branch:
# 当前分支不是此分支 判断本地是否有此分支
if branch not in all_branch:
git_info = git('branch -r')
print(git_info)
all_origin_branch = git_info.replace(' ', '').split('\n')
origin_branch = 'origin/' + branch
if origin_branch not in all_origin_branch:
return 0
else:
git_info = git('checkout -b {0} {1}'.format(branch, origin_branch))
print(git_info)
git_info = git('branch')
print(git_info)
return 1
else:
# 本地有此分支，切换至此分支 拉取
git_info = git('checkout {0}'.format(branch))
print(git_info)
git_info = git('pull origin {0}'.format(branch))
print(git_info)
git_info = git('branch')
print(git_info)
return 1
else:
# 拉取最新
git_info = git('pull origin {0}'.format(branch))
print(git_info)
git_info = git('branch')
print(git_info)
return 1
if __name__ == '__main__':
print('--------------------------------- git log start ---------------------------------')
result = update_git(project_path, branch)
print('--------------------------------- git log end ---------------------------------')
sys.exit(result)
2、Unity 提供打包接口
做过相关自动化打包共具的小伙伴应该都知道Unity提供的MenuItem类，可以将接口暴露在Unity界面的菜单栏中，通过选中点击的方式执行函数，另外Unity也支持命令行，可以通过shell活着批处理来调用制定类中的函数，可以参照官方的UnityCommandLine来了解。以下是Unity的打包函数例子：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using System;
public class AutoBuildTools {
/// <summary>
/// 获取参数
/// </summary>
/// <returns> 参数值 </returns>
/// <param name="indexFromEnd"> 从后往前数第几个参数 </param>
static string GetParam(int indexFromEnd){
string[] args = Environment.GetCommandLineArgs();
return args [args.Length - 1];
}
public static void BuildPackage(){
string platform = GetParam (2);
string buildPath = GetParam (1);
Debug.LogFormat ("BuildPackage platfotm is {0}", platform);
if (platform == "iOS") {
BuildMenuItem.BuildXcode ();
} else if (platform == "Android") {
BuildMenuItem.BuildPackage ();
}
}
public static void BuildAssetBundle(){
string platform = GetParam (1);
Debug.LogFormat ("BuildPackage platfotm is {0}", platform);
if (platform == "iOS") {
BuildMenuItem.BuildAssetBundle_iOS ();
} else if (platform == "Android") {
BuildMenuItem.BuildAssetBundle_Android ();
}
}
}
public class BuildMenuItem{
[MenuItem("AutoBuildTools/BuildAssetBundle/iOS")]
public static void BuildAssetBundle_iOS(string buildPath){
Debug.LogFormat ("AutoBuildTools/BuildAssetBundle/iOS, buildPath is {0}", buildPath);
}
[MenuItem("AutoBuildTools/BuildAssetBundle/Android")]
public static void BuildAssetBundle_Android(string buildPath){
Debug.LogFormat ("AutoBuildTools/BuildAssetBundle/Android, buildPath is {0}", buildPath);
}
[MenuItem("AutoBuildTools/BuildPackage")]
public static void BuildPackage(){
Debug.Log ("AutoBuildTools/BuildPackage");
}
[MenuItem("AutoBuildTools/BuildXcode")]
public static void BuildXcode(){
Debug.Log ("AutoBuildTools/BuildXcode");
}
}
3、编写外部打包工具脚本
外部打包工具其实就是将前两步串接起来，根据需求编写不同的shell活着bat逻辑，来调用不同的Unity提供的打包函数。直接上脚本
BuildAssetBundle.py
#coding=utf-8
#liyiyuan 2019-06-04
import sys
import datetime
import subprocess
BRANCH = sys.argv[1]
PLATFORM = sys.argv[2]
UNITYPATH = '/Applications/Unity/Unity.app/Contents/MacOS/Unity'
GITOPERATIONPATH = '/Users/liyiyuan/Projects/JenkinsScripts/git/GitOperation.py'
PROJECTPATH = '/Users/liyiyuan/Priject/Unity/#PLATFORM#/Test'
star_time = datetime.datetime.now()
def log_complete():
end_time = datetime.datetime.now()
print('【INFO】build complete, duration : ', (end_time - star_time))
if __name__ == '__main__':
if PLATFORM == 'iOS':
print('【INFO】start ios build asset bundle')
elif PLATFORM == 'Android':
print('【INFO】start android build asset bundle')
else:
print('【ERROR】other error')
PROJECTPATH = PROJECTPATH.replace('#PLATFORM#', PLATFORM)
update_git_result = subprocess.call(f'python {GITOPERATIONPATH} {PROJECTPATH} {BRANCH}', shell=True)
if update_git_result == 1:
print('------------- upgrade success')
# shell 命令行构成
# [unity path] -quit -projectpath [project path] -executeMethod [class.method] [platfotm]
subprocess.call('{0} -quit -projectPath {1} -executeMethod AutoBuildTools.BuildAssetBundle {2}'.format(UNITYPATH, PROJECTPATH, PLATFORM), shell=True)
elif update_git_result == 0:
raise SystemExit('【ERROR】git upgrade error !')
log_complete()
BuildPackageOrXcode.py
#coding=utf-8
#liyiyuan 2019-06-04
import sys
import datetime
import subprocess
BRANCH = sys.argv[1]
PLATFORM = sys.argv[2]
UNITYPATH = '/Applications/Unity/Unity.app/Contents/MacOS/Unity'
GITOPERATIONPATH = '/Users/liyiyuan/Projects/JenkinsScripts/git/GitOperation.py'
PROJECTPATH = '/Users/liyiyuan/Priject/Unity/#PLATFORM#/Test'
BUILDPATH = '/Users/liyiyuan/Priject/Unity/Build/#PLATFORM#'
star_time = datetime.datetime.now()
def log_complete():
end_time = datetime.datetime.now()
print('【INFO】build complete, duration : ', (end_time - star_time))
if __name__ == '__main__':
if PLATFORM == 'iOS':
print('【INFO】start ios build asset bundle')
elif PLATFORM == 'Android':
print('【INFO】start android build asset bundle')
else:
print('【ERROR】other error')
PROJECTPATH = PROJECTPATH.replace('#PLATFORM#', PLATFORM)
BUILDPATH = BUILDPATH.replace('#PLATFORM#', PLATFORM)
update_git_result = subprocess.call(f'python {GITOPERATIONPATH} {PROJECTPATH} {BRANCH}', shell=True)
if update_git_result == 1:
print('------------- upgrade success')
# shell 命令行构成
# [unity path] -quit -projectpath [project path] -executeMethod [class.method] [platfotm] [build path]
subprocess.call('{0} -quit -projectPath {1} -executeMethod AutoBuildTools.BuildPackage {2} {3}'.format(UNITYPATH, PROJECTPATH, PLATFORM, BUILDPATH), shell=True)
elif update_git_result == 0:
raise SystemExit('【ERROR】git upgrade error !')
log_complete()
