Eclipse installer can't find my jdk or jre [message #1847896]

According to the installer it's version

plugins/org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar

I have OpenJDK 17 installed, among others.

I was trying to reinstall eclipse because my version suddenly stopped auto-completing anything in java.awt.*. I see from other threads here that java.awt.* is now built-out. so... what is the new hotness that everyone uses to make interfaces? I'm deep into GridBagConstraints.

You can fix that by modifying the values on the Type Filters preference page, once you have Eclipse open, of course. Unless
you're working with Java 8, it might be time to uninstall it.

That's the thing - I have newer JRE/JDK, so why is the installer looking in the wrong place? IDK where to file a ticket.

I don't know which installer you are using, but the latest ones contain a JRE so would not have the problem you show. The older installers look in the registry (but the Java vendors keep changing the keys under which they store the information such that an other installer can't find a newer JRE at a newer key location). The installers also look on your PATH and JAVA_HOME environment variables and is not finding a JRE there either. Perhaps it's finding stale entries in your registry or in those environment variables.

You can use this "latest" installer to install any older version of Eclipse if that's what you need to do:

But the problem you are trying to fix is easily addressed via Nitin's suggestion.
