Hi,

Welcome to the community and thanks for this report!

What version of SonarQube for Visual Studio are you using?

 
Thx,
Ann

Hi,

I am using SonarQube for VisualStudio 2022 8.13.0.12427

Hi,

Thanks for that detail. Iā€™ve flagged this for the team.

Hi @padzeralu,

Thanks for reporting this issue! Since Java is embedded in the extension, the error ā€œError: could not find java.dllā€ could indicate a problem with the installation or that some files were blocked by security software.

I would suggest you to reinstall the extension and at the same time try checking your firewall or antivirus if they flagged and blocked the extension or any of its files.

:one: Reinstall the Extension

  • Uninstall the extension completely.
  • Restart Visual Studio.
  • Reinstall the latest version of the extension to ensure all files are properly installed.

:two: Check for Security Software Blocking

  • Your firewall or antivirus might have flagged and blocked the embedded Java files.
  • Try checking your antivirus/firewall after reinstalling the extension.
  • In that case you could add an exception for the extension in your security software.

If the issue persists, please let us know!

:three: Workaround: Manually specify a Java Installation

  • Another possible but less ideal solution would be to install java on your machine and let the extension use that installation.
  • To specify a JRE, go to Extensions > SonarQube for Visual Studio > Optionsā€¦ > SonarQube for Visual Studio > General > Java Home , add the path to your JRE, and restart your IDE to apply the setting.

Kind regards,
Vasileios Naskos

After installing the recent update for both VS2022 and SQ extension the error output log looks slightly better but still unable to connect to server.

Thanks for the update, itā€™s good to hear that weā€™re in a better state!

It looks like thereā€™s still some work to do to fully understand and resolve the issue. To dig deeper, could you please share the full Verbose logs?

I appreciate your patience and understanding as we work through this! :grin:

Hi,

I switched on Verbos logs and also updated Visual Studio again, but that didnā€™t help much so I just went ahead and installed JDK and specified the path in options.

This is the version I am using is
https://download.java.net/java/GA/jdk23.0.2/6da2a6609d6e406f85c491fcb119101b/7/GPL/openjdk-23.0.2_windows-x64_bin.zip

However, the extension is still failing to connect to server.
