How to prevent upgraded Eclipse Oxygen from automatically downgrading
提问by anothernode
I'm trying to Upgrade Eclipse Neon to Oxygen on Windows 10.
我正在尝试在 Windows 10 上将 Eclipse Neon 升级为 Oxygen。
I started Eclipse with Administrator privileges and then followed the instructions described in the Eclipse Wiki.
我以管理员权限启动 Eclipse，然后按照Eclipse Wiki 中描述的说明进行操作。
The upgrade runs without errors and prompts for a restart. After the restart, Oxygen comes up without errors and everything seems fine. But when I close Eclipse and start it again, it's back to Neon, duh.
升级运行没有错误并提示重新启动。重新启动后，Oxygen 没有错误出现，一切似乎都很好。但是当我关闭 Eclipse 并再次启动它时，它又回到了 Neon，呃。
Oh, how I miss Arch Linux's pacman...
哦，我多么想念 Arch Linux 的pacman......

I had the same problem. Every restart after the initial upgrade from Neon to Oxygen, I got a "Requirements Update" dialog that prompted me to downgrade some of my components from 4.7 to 4.6 after which point I was back on Neon. Oops. Apparently "Oomph" still thought I should be on Neon and was trying to "fix" things.
我有同样的问题。从 Neon 初始升级到 Oxygen 后，每次重新启动时，都会出现“要求更新”对话框，提示我将某些组件从 4.7 降级到 4.6，之后我又回到了 Neon。哎呀。显然，“Oomph”仍然认为我应该在 Neon 上并试图“修复”一些事情。
I followed the following step outlined here:

open the Installation setup (Navigate -> Open Setup -> Installation) and in the properties view change the product version to say Oxygen
打开安装设置（导航 -> 打开设置 -> 安装）并在属性视图中将产品版本更改为氧气
After I did this, Oomph left me on Oxygen after this.
在我这样做之后，Oomph 在这之后让我继续使用 Oxygen。

I "solved" the problem by
我“解决”了这个问题
- downloading the Oxygen installer,
- installing Eclipse Oxygen as a separate instance,
- installing all the plugins I need in Oxygen,
- exporting the preferences from Neon and importing them in Oxygen.
- 下载氧气安装程序，
- 将 Eclipse Oxygen 作为单独的实例安装，
- 在 Oxygen 中安装我需要的所有插件，
- 从 Neon 导出首选项并将其导入 Oxygen。
A bit annoying, but it works and is probably still way more effective than figuring out what is going wrong with Eclipse's upgrade mechanism...
有点烦人，但它有效并且可能仍然比找出 Eclipse 升级机制出了什么问题更有效......
