This is my Eclipse IDE:

Eclipse IDE for Enterprise Java Developers (includes Incubating components)

Version: 2020-09 (4.17.0)
Build id: 20200910-1200

Anyone encountered similar problems?

Edit: Okay I just tried installing a different Marktplace Extension - eclipse FX and it installed without any problems..

I don't know if I am too late but I seem to have got the same issue. I solved it by manually downloading the plugin from Sourceforge.

Go to the link Source Forge JasperSoft update site

This will take you to the updatesite page where you see a lot of versions. Make sure you click on 6.14 or lower and download the full-site.zip file.

Now go to Eclipse, Help > Install New software > Click on Add button > Click New button and then select the Zip file that you downloaded.

Now, once that's installed, restart Eclipse and go to Eclipse Marketplace, go to installed tab and search for Jaspersoft and click on the update button. Once Eclipse restarts, you should be good to go. Have any issues, just leave a comment.
