So I have been learning basic Java on this eclipse: "eclipse-inst-win64" and on this JDK version "jdk-12.0.2_windows-x64_bin" and everything works fine. So, I started a new course on spring and the teacher told us to download this version of eclipse: "Eclipse IDE for Enterprise Java Developers". I downloaded this file "eclipse-jee-2019-12-R-win32-x86_64" and when I extract the zip file and run the Eclipse application, this error pops up which is in the screenshot picture.
It worked fine for the instructor in the video.
