How can I use JRE 1.8 with Eclipse Neon?

Question

Trying to run Eclipse Neon I'm getting this error:

To open “Eclipse” you need to install the legacy Java SE 6 runtime.

Instead of the legacy JRE, I have already installed JRE 1.8 from Oracle:

➜  /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version

java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

However, I can also see it is not available in the path:

➜  java -v
No Java runtime present, requesting install.

➜  /usr/libexec/java_home -v 1.8
Unable to find any JVMs matching version "1.8".
No Java runtime present, try --request to install.

➜  ls /Library/Java/JavaVirtualMachines

On macOS you must install the full JDK to get complete Java support. The JRE is not sufficient as it only installs the browser plugins.

The current download for the JDK is here
