When I click on update it says:
This is an emergency update. Continue?
To lower the risks of problems duringthis update it will be implied thta you accept new licenses or unsigned content.
I have installed Java JDK 15.0.2 just before.
How can I make this Eclipse Installation work?
Thank you in advanced.
