Hi Jens I would use the second way which is described in more detail. If you use the first way, make sure that you select "Update my installation...".
Thinking of it, we should probably remove the first install method from the MPE.

Pre-requisite: You need Oxygen (4.7 or above) Eclipse SDK or maintenance(M) builds (available from http://download.eclipse.org/eclipse/downloads/) <- got that The Java? 9 support also works when the IDE is launched with a Java? 8 VM. There is no need to switch Java? 9 VM for that. <-- ok tried both For any Eclipse install <= Oxygen 1 you have to add --add-modules=ALL-SYSTEM. For more details and potential issues see https://wiki.eclipse.org/Configure_Eclipse_for_Java_9. <-- did that as well You need Java? 9 JDK ( Available from the JDK9 pointer at the parent site: http://www.oracle.com/technetwork/java/javase/downloads/index.html) <-- check To try out Java 9 support in Eclipse, you can follow any of these: Update your Eclipse 4.7 build using this update site: http://download.eclipse.org/eclipse/updates/4.7-U-builds. In Eclipse, go to Help > Install New Software... and uncheck "Group items by category". Select "Eclipse SDK" from the list of items and proceed with the installation. <!-- didn't do that .. but I can use "any" of these Update your Eclipse 4.7 build for committers ( https://www.eclipse.org/downloads/packages/eclipse-ide-eclipse-committer.. .) using Eclipse Marketplace entry (currently, needs some additional steps): <-- went with that one Drag and drop the Install button on this web page to your running Eclipse workspace. This will open the Eclipse Marketplace dialog. <-- dialog open Click the link "One solution selected" at the bottom. <-- doesn't appear .. so the next bullet steps are not working either In the Java 9 support entry, press "Update Pending" button. Press the same button again, now named "Update". Ignore the progress bar message at the bottom. On the next page which comes up, make sure "Update my installation..." is selected and press "Confirm". Accept the license and proceed with the installation. I did install Eclipse Comitters edition with the Eclipse Installer, maybe that is an issue?

I just tried again and could install it into the committers package.

If you locate the Java 9 feature, then it says "Installed". But there is no way to actually install this. I really think there should be some note on download.eclipse.orgwhich explains that people have to wait for Oxygen.1a, otherwise this may just cause frustration.

You have to install the Java9 support from the Eclipse Marketplace into it. This will change with Oxygen.1a (shipping Oct 11), which will include Java9 support ouf-of-the-box. Hope this helps! Cheers, -Martin > I got some troubles on getting Oxygen.1 ready for Java 9 ... I don't want to run Oxygen.1 on Java 9, but use it on Java 8, to develop a Java 9 application.
