However if I copy UMLet Eclipse plugin jar into dropins under Eclipse IDE for Eclipse Committers,  I can’t even see "UMLet/Diagram" when I click "File/New/Other.." from the menu”.

I was under the impression that the "dropins" mechanism wasn't supported anymore, but it's still mentioned in the documentation (https://help.eclipse.org/2019-12/topic/org.eclipse.platform.doc.isv/reference/misc/p2_dropins_format.html), so maybe not? Alternatively, try installing the plugin using "Install New Software". If UMLet does not provide a p2 repository ("update site"), then I seem to remember that there is a way of generating one from a bare plugin using some command line Eclipse invocation, but I don't remember the details. (Check the docs, possibly https://help.eclipse.org/2019-12/topic/org.eclipse.platform.doc.isv/guide/p2_publisher.html)

But then aren't you trying to build the UMLet plugin yourself, so you shouldn't need to install a pre-built one?

I'm sorry, I'm unfamiliar with these errors and can't help you with them. Last time I used the "Getting started with CDT development" instructions a few years ago, they worked for me.
