Please provide
- Operating system: Windows 11
- IDE name and version: Eclipse 2025_06
- SonarQube for Eclipse plugin version: unknown
- Programming language you’re coding in: Java
The problem:
The installation routine of SonarLint in Eclipse 2025_06 is broken, because of some certification issues. See the screenshot for details.
Please fix or provide some other installation way.
The error:
Unable to read repository at https://eclipse-uc.sonarlint.org/compositeContent.xml.

Hello Sonar Community,
Is there any information about support for the Eclipse plugin? Has Eclipse support been discontinued?
Best regards,
Michael
I got the Same error. It seems to be an issue with the certificate of the Website.
Hey @michaelbsb,
Instead of the Update Site you used, can you try to use:
https://binaries.sonarsource.com/SonarLint-for-Eclipse/releases/
This page is the one that the other one is pointing to. This page cannot be browsed, so don’t get confused if you open it in the browser, it works well when used in the IDE.
Cheers

Hi EclipseWizard,
Thank you for your feedback. Unfortunately, this URL doesn’t work in Eclipse 2025_06 either. This appears to be a certification issue with Eclipse 2025_06.
Both URLs work in Eclipse 2023-09, for example.
Cheers!

Hi @michaelbsb,
testing once again with a fresh Eclipse JEE 2025-06 installation on Windows, I see no issues with the Update Site I provided (see the screenshots below).
Before that, I tested with an Eclipse installation that I automatically updated from 2025-03 to 2025-06.
A good approach would be to compare the old installation you have with the new one. Maybe you added certificates to the old installations JRE it is running with?
Otherwise the logs inside the installation (in the configuration folder) might yield more information on what might be broken with the Eclipse installation you have.
Cheers
