TimerJob无法发布新版本问题

最近遭遇发布TimerJob在测试环境发布没有问题，但是到正式环境发布总是无法执行及调试的问题，经过几天的努力，终于解决了这个问题，下面记录下遭遇的问题。

Windows 2008，SharePoint  2013，测试环境为单机，生产环境为双AP，一DB。双AP中一个是AP+管理中心，另外一个只做索引爬网。

测试环境一切正常，可以执行调试，部署至于正式环境会碰到：错误 2 部署步骤“激活功能”中出现错误: Feature with Id 'xx' is not installed in this farm, and cannot be added to this scope.该错误正常，去管理中心部署解决方案至site即可。

下面问题来了，解决方案中有两个Feature，一个是包含了可视化的WebPart的，另外一个是激活后新建TimerJob的。TimerJob这个无法执行无法调试。

1、更改了TimerJob的名称，但是依旧在重新激活Feature后显示旧的TimerJob名称。

2、移除C:WindowsMicrosoft.NETassemblyGAC_MSIL中相应的dll，依旧无法执行调试。

3、移除网站目录下bin目录的dll，依旧没解决。

4、整个盘搜索相关dll，全部删除，依旧没有解决。

5、。。。

以上皆重启多次IIS及Timer Service。

后终于想明白，这可能是Timer Job的缓存导致的，google搜索"sharepoint timerjob cache"，果然发现：，https://nickhobbs.wordpress.com/2012/06/14/sharepoint-2010-powershell-to-clear-the-timer-job-cache：

• Stop Windows SharePoint Timer Service from Windows Services
• Open C:ProgramDataMicrosoftSharePointConfig<<GUID>> folder
• Delete all the XML files inside the GUID folder.
• Open the Cache.ini file and change the value to 1.
• Save Cache.ini file
• Restart Windows SharePoint Timer Service from Windows Services

注意需要在每个APP上执行一次。

我的操作：先收回解决方案，再执行以上操作，再部署，激活，问题解决。

作者还做了个脚本：
