Hi All,
New to eclipse. Need to convert existing java 8 app to java 15/17.
Got eclipse 2020-12 but I am unable to import the project in my new eclipse installation.
Old eclipse using jre 8 works fine.
How can I import/use old java 8 project in eclipse 2020-12 and convert it to java 15/17?
Any help will be greatly appreciated.
Thanks
Ranajit

What specifically is failing with regard to importing your new projects into a new Eclipse Installation? Generally you can configure the IDE to use any JRE/JDK via Window -> Preferences -> Java -> Installed JREs and adding a Java 8 (or whatever) JRE/JDK there.

Well, to be specific.

You are not asking to port an Java 8 application to Java 15 are you? As Eclipse will not do that.

I think you are asking how to convert a Eclipse Java 8 PROJECT to load on a later version of the Eclipse IDE running Java 15 environment.
