Before upgrading I first check the availables web sites for update. I disable all from the previous releases and start by performing an update on the already installed components. After this upgrade I just add
在升级之前，我首先检查可用网站以进行更新。我禁用了以前版本中的所有内容，并首先对已安装的组件执行更新。这次升级后，我只是添加
http://download.eclipse.org/releases/mars
http://download.eclipse.org/releases/mars
and upgrade to the new release of eclipse.
并升级到新版本的eclipse。

I don't know how relevant it is but for the record I not only added the mars release update site but also this one: http://download.eclipse.org/eclipse/updates/4.5
我不知道它有多相关，但为了记录，我不仅添加了 mars 发布更新站点，还添加了这个站点：http: //download.eclipse.org/eclipse/updates/4.5
Maybe a duplicate? If so, let me know ;)
也许是重复的？如果是这样，请告诉我；）

This is a bad idea. If you upgrade your Eclipse, it will be difficult to fall back when you want to (and you will).
这是一个坏主意。如果您升级您的 Eclipse，那么当您想要（并且您会）时将难以回退。
Better is to create a new Eclipse instance and new (set of) workspace(s) for Mars. Then either point to your existing Team repositories or import your existing projects.
更好的是为 Mars 创建一个新的 Eclipse 实例和新的（一组）工作区。然后指向您现有的团队存储库或导入您现有的项目。
