SonarLint plugin for IntelliJ IDEA suddenly stopped working - shows "No issues to display"

SonarLint plugin for IntelliJ Idea suddenly stopped working.

Although it previously found a lot of issues, now there are no issues at all. However there is no error message visible and everything seems in order.

No "well-known method" (restart IDEA, restart the computer, invalidate caches, re-configure the plugin, reinstall the plugin, re-create the project) helps.

Solution

  • IntelliJ accidentally switched into Power Save Mode (File | Power Safe Mode). As for why, I have no idea [pun intended], but I found other people complaining about some problems with IDEA when their laptop wakes up from sleep/hibernation(?) (This is just an unconfirmed rumour and I am not sure that it is this what caused the unwanted configuration change.)

    I didn't find a fully exhaustive and comprehensive documentation on the JetBrains site, but in general, when this switch is active, IDEA doesn't perform a lot of various background activities to save power.

    All what you need to get the SonarLint plugin back to work is to turn the Power Save Mode off again.

    Based on this problem, the Sonar team created a ticket SLI-1256 "Improve how we react to the Power Save Mode" to address it.
