编译版本号迭代

python实现Jenkins版本号迭代

背景:

在持续集成过程中每天可能编译多个版本,这些版本的版本号需要按照规定的格式进行迭代,可以通过python脚本获取Jenkins上一次编译成功的状态来定义当前编译的版本号。

实现步骤:

1、安装Jenkins插件inject environment variables

2、使用python脚本将生成的版本号写入一个临时文件中

3、使用inject environment variables插件读取版本号作为环境变量

 

代码实现:

#!/usr/bin/python # -*- coding: utf-8 -*- import os, io, sys, requests, subprocess, json, re from datetime import datetime from subprocess import Popen, PIPE, call, check_call if __name__ == "__main__": dt = datetime.now() year = dt.strftime('%y') unix_week = int(dt.strftime('%W')) + 1 week = str(unix_week) day = dt.strftime('%w') r = requests.get('http://localhost:8080/job/Jenkins_api_test/lastSuccessfulBuild/api/json?', auth=('username', 'password')) if r.status_code == requests.codes.ok: result = json.loads(r.text) print('result:', result) if result['description'] != 'null': lastBuildNumber = result['description'] print('lastBuildNumber:', lastBuildNumber) else: lastBuildNumber = 'None' print('lastBuildNumber is empty!!!') if lastBuildNumber: buildWord = lastBuildNumber[-1:] lastBuildDigital = lastBuildNumber[:-1][2:] newbuildWord = chr(ord(buildWord)+1) nowTime = year + week + day if lastBuildDigital == nowTime: BUILD_NUMBER = 'DB' + nowTime + newbuildWord else: BUILD_NUMBER = 'DB' + nowTime + 'A' else: print('count the BUILD_NUMBER directly!') BUILD_NUMBER = 'DB' + year + week + day + 'A' with open('BUILD_NUMBER.property', 'wt') as f: f.write('BUILD_NUMBER=' + BUILD_NUMBER) print('BUILD_NUMBER:' + BUILD_NUMBER)

 读取成功后这个参数就可以作为后续脚本的环境变量:

实现效果:

当然也可以把字母迭代修改为按数字迭代,以需求为准。
