Hi ABDERRAHIM TALIBI (@abdertalibi-gif), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Possible workarounds

• Clear the installer cache and retry:

  • On Linux: remove ~/.vscode-java-installer (or %TEMP%\vscode-java-installer on Windows) and reinstall the Java Extension Pack.
  • Or delete the corrupt VSIX in your extensions folder: rm -rf ~/.vscode/extensions/vscjava.vscode-java-pack-* then reinstall.

• Install the pack manually via CLI:

  code --install-extension vscjava.vscode-java-pack --force

• If you’re using Code - OSS (which lacks Microsoft’s signing key), switch to the Open VSX registry by adding to settings.json:

  "extensionsGallery": {
    "serviceUrl": "https://open-vsx.org/vscode/gallery",
    "itemUrl": "https://open-vsx.org/vscode/item",
    "controlUrl": "https://open-vsx.org/vscode/control"
  }

• Collect detailed logs as requested (F1 > Open View… > Shared) or attach ~/.vscode-java-installer/log.txt to help diagnose further.
