I have tried to install it from Eclipse Marketplace and nothing goes wrong apparently, but after restarting IDE nothing has change. Using right click -> New... , "Jasper report" still not appearing and there is not reference to Jasper in Window -> Preferences. If I go again to Marketplace, it appears as Installed. I have tried to uninstall and install again but I have the same problem.
I am using Eclipse 2020-06 (4.16.0) and I am trying to install Jaspersoft Studio 6.20.0
