以前提到过SVN版本控制器和客户端的安装和配置，这里再在说一下在编译器中怎么使用SVN，使其既可以单独使用，也可以配合SVN客户端一起使用。
由于编译器种类众多，插件种类也不同，这里只简单介绍下Eclipse的插件安装。
我用的版本是Eclipse3.2.2+MyEclipse_5.1.1，由于本身只有CVS而没有集成SVN，所以要想使用SVN做版本控制只好装一个Eclipse插件Subclipse，Subclipse的详细安装过程在其官方网站http://subversion.tigris.org写的很清楚，还带配图，我就直接copy了：一、InstallSubclipseinEclipse3.

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
