I installed Eclipse 2020-03 (which is 4.15, I think). And then I tried to install the plugin to support Java 14. It failed to install two of the components. When I switched a project to Java 14 it failed abysmally -- the first class in the list was just covered with red X's but none of the classes in the project tree were marked as having errors.
Thanks for your reply. At least mine wasn't as abysmal as that, about 98% of my projects compiled and ran without a problem. At least I can use 13 as a work around. I'm surprised this hasn't set off alarm bells yet.
I'm content with Java 13 for the time being. I've switched over to refactoring code which needed it and to implementing some of the useful features of versions between 1.8 and 13. When they put out the next version of Eclipse I'll consider upgrading to that.
I found that Eclipse has a version 4.16M1 (2020-06) but it appears to only be available as a zip and not an install. The zip file does not have the JDT so lots of things don't work. I'm not sure how one would manually download and install the JDT.
