How do I get Eclipse 2020 to behave like Eclipse 2019? [message #1835244]

I just upgraded my OS from Linux Mint 19.3 to Linux Mint 20.

I previously had Eclipse 2019-03 on Mint 19.3.

After upgrading, I installed Eclipse 2020

When I typed the name of an object in the editor in Eclipse 2019 it would list the names of all available methods for that object. But Eclipse 2020 doesn't do that.

Can I make Eclipse 202 behave like Eclipse 2019?

Or can I install Eclipse 2019?

When I tried to launch the Eclipse 2019 executable on Mint 20, it told me, "The Eclipse executable launcher was unable to locate its companion shared library."

Which editor? Are you sure you installed Eclipse 2020 with the same feature set as 2019-03?

I don't know what you mean by "Which editor?"
I installed Eclipse 2020 from the main Mint repository using the Software Manager.
When I installed Eclipse 2019, I installed it from a tar.gz archive that I had downloaded some time ago.
In both cases, the only option I was asked to choose was to point to my workspace folder.
In Eclipse 2020, I did try to search for an option in preferences that might say something like "edit for Java source," but I couldn't find an option like that.

Update..
Out of desperation, I uninstalled Eclipse 2020 and then re-installed it.
It's now working! Yay! :-)
When I type the name of an object, it now gives me a list of all available methods for that object!
I'm not sure what changed between yesterday and today.
Maybe launching Eclipse 2019 yesterday added some dependencies that were missing in Eclipse 2020.
Or maybe that had nothing to do with it. ¯\_(ツ)_/¯

Do I need to mark this thread RESOLVED in some way?
