Target is not a JDK root. System library was not found. Eclipse Oxygen 4.7 + Java9 error

I'm trying to test JDK9 (jdk-9-ea+147 version) with Eclipse Oxygen IDE.

I've installed jdk along with jre. From Eclipse Market Place I've installed Java9 Beta extension:

The problem is, when I'm trying to add new installed jre from Eclipse I get following error:

Interesting thing is that this error doesn't occur with installations of previous JDK versions:

Does anyone encounter simillar problem with Eclipse Oxygen? Any feedback is appreciated.

I was facing the same problem for the latest JDK."jdk-18_windows-x64_bin.exe" However it is resolved by installing this eclipse https://www.eclipse.org/downloads/download.php?file=/oomph/epp/oxygen/R/eclipse-inst-win64.exe.

Give it a try, I hope this will work for you too! Cheers!

I'm also faced this issue "Target is not a JDK root. System Library was not found" for Java 11 and I have done some workaround and got to know, this is related to the version we are using either eclipse or sprint tool suite. So i figured out the correct version and posted below.

Java 9 Supports:

Spring Tool Suite:3.9.0
Eclipse:Oxygen (4.7)

Java 10 Supports:

Spring Tool Suite:3.9.4
Eclipse: Oxygen (4.7.3) and Above

Java 11 Supports:

Spring Tool Suite: 3.9.7
Eclipse: Photon 4.8, 4.10 (officially supports)

Below are references i used:

STS
Eclipse

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-oxygen to be able to use Java9 or you can update from "Help" menu bar.

I've just successfully tested JDK9 with Eclipse Oxygen IDE following the approach you detailed.

Here are the details of my installation (under Windows 10):

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:

Also, see https://wiki.eclipse.org/Java9/Examples for further details.

This looks like Eclipse bug 494481.

Unfortunately there is currently no fix or workaround listed for the bug.
