Thanks for sharing, that’s helpful!
In the latest version of SQ:IDE, we’ve transitioned to using IntelliJ’s secure password storage instead of the older sonarlint.xml file, which previously held encrypted credentials. This is the recommended approach for security. The location of this secure storage is entirely managed by your IntelliJ IDE settings, and we do not have control over it, as stated in their doc:
Storage
The default storage format depends on the OS.
Users can override the default behavior in Settings | Appearance & Behavior | System Settings | Passwords.
Perhaps we could improve the user feedback and display some explanations instead of failing with this generic error.
