I've just successfully tested JDK9 with Eclipse Oxygen IDE following the approach you detailed.
我刚刚按照您详细介绍的方法使用 Eclipse Oxygen IDE 成功测试了 JDK9。
Here are the details of my installation (under Windows 10):
以下是我的安装详细信息（在 Windows 10 下）：
I downloaded and installed Java jdk-9+181 from http://jdk.java.net/9/
I downloaded and installed Eclipse Oxygen from https://www.eclipse.org/downloads/download.php?file=/oomph/epp/oxygen/R/eclipse-inst-win64.exe
I started Eclipse and attempted to add JRE9 (Windows -> Preferences -> Java -> Installed JREs -> Add...)
I got the error reported in the OP ("Target is not a JDK root...").
I then installed Java 9 Support (BETA) for Oxygen as detailed here: https://marketplace.eclipse.org/content/java-9-support-beta-oxygen
I restarted Eclipse and tried to add JRE 9 again. This time it worked fine:
我从http://jdk.java.net/9/下载并安装了 Java jdk-9+181
我从https://www.eclipse.org/downloads/download.php?file=/oomph/epp/oxygen/R/eclipse-inst-win64.exe下载并安装了 Eclipse Oxygen
我启动了 Eclipse 并尝试添加 JRE9（Windows -> Preferences -> Java -> Installed JREs -> Add...）
我收到了 OP 中报告的错误（“目标不是 JDK 根目录...”）。
然后我为 Oxygen 安装了 Java 9 Support (BETA)，详细说明如下：https: //marketplace.eclipse.org/content/java-9-support-beta-oxygen
我重新启动了 Eclipse 并尝试再次添加 JRE 9。这次效果很好：

Oxygen does not come with java9 support. You need to install the eclipse Java9 support patch from the market place https://marketplace.eclipse.org/content/java-9-support-beta-oxygento be able to use Java9 or you can update from "Help" menu bar.
Oxygen 不支持 java9。您需要从市场https://marketplace.eclipse.org/content/java-9-support-beta-oxygen安装 eclipse Java9 支持补丁才能使用 Java9，或者您可以从“帮助”菜单栏更新.
