Problem while installing AEM Developer Tools for Eclipse

Hi,

I have imported my maven project into eclipse and using "install new software" option(comes under Help) I have added AEM Server(Name - AEM & Location - https://eclipse.adobe.com/). After that when I opened AEM as Perspective, I could see this option - No Servers are available. Click this link to create new server to create new server. There I have selected Adobe Experience Manager from Adobe and gave Server host name and server name. But in the next page instead of showing the resources from my imported project, it is empty and showing - There are No resources that can be added or removed from the server.

I am able to build my process without any isue, but not able to install AEM Developer tools.

I am using eclipse - Version: 2020-09 (4.17.0) and Maven - version 3.9.0 and I tried with latest version of eclipse as well. I tried many things - reinstalling the eclipse, re-importing the projects, adding maven plugins from marketplace etc, but nothing is working so far.
