Eclipse is poor tooling for teaching. Far too many buttons and noise that gets in the way. But the opposite, programming with no debugger and no linter is just as bad. It punishes you for getting the smallest syntax mistakes by waiting for the compiler and reading out erroneous messages.

A debugger makes it far better to understand the execution of code line by line, and should be standard in education, but it's not.

I feel that visual studio code, with some modifications, would be perfect to begin with. Then when building things at a higher level, introduce why to use eclipse, like how it handles packages, etc.
