Error Installing DevStyle plugin for Eclipse

I installed the current latest version of eclipse (202006) CDT. I have tried installing the DevStyle plugin and received the following error:

Cannot complete the install because some dependencies are not satisfiable
  Software being installed: a.jre.javase 14.0.0
  Software currently installed: C/C++ Autotools support 9.11.1.202004012023 (org.eclipse.cdt.autotools.feature.group 9.11.1.202004012023)

This error message is fairly cryptic to me. I looked a similar problem here. But this specifies Java 11 and Java 14. I don’t know how this relates to my JRE 1.8.0_251 (Version 8 Update 251). I also don’t understand the new scheme for Java. Does Oracle not release JRE’s anymore?

I don’t need to program in Java. I only need runtime environment to run eclipse, so I don’t want/need full JDK (especially since this seems to require some licensing/commercial aspects). I also believe I will get similar errors with other plugins that I intend to install.

So two questions here:

Is there a way to get JRE’s for Java 11 or Java 14?
What version of JRE/JDK do I need to get this to work?

Answer

To: osgi.ee; (&(osgi.ee=JavaSE)(version=11))

This means that at least Java 11 is required by this code. It will not run with Java 8. You will have to move to a newer Java.

Newer versions of Java only have a JDK with no separate JRE. The Java builds on the OpenJDK site have a ‘normal’ free license and are essentially to same as the Oracle Java.
