First, you need to get the correct install most probably, here is the Oxygen 4.7 M6 link : http://download.eclipse.org/eclipse/downloads/drops4/S-4.7M6-201703082000/

Or the direct link to the .tar.gz

Then (after you untar the archive), go to :

Eclipse.app/Contents/Eclipse/eclipse.ini

and add one parameter after -vmargs. It should look like this:

-vmargs
--add-modules=java.se.ee

This will allow you to start the Eclipse under jdk-9.

In case you want to install the jdk-9 plugin (so that you could compile code under jdk-9): you need to install the Experimental Plugin for jdk-9. There were some problems with that (I filed a bug that was closed), see this thread. At the end there is the link for on how to get the plugin.

Then you need to follow the exact instructions here for it to actually work.
