SonarScanner on Windows: "Failed to delete temp folder" + ESLint deprecation error

SonarQube Server / Community Build

Issue 1 - Temp folder cleanup race condition

Every run produces:

The scanner locks the .pb file during its own JVM shutdown while simultaneously trying to delete it. We confirmed with Sysinternals handle64.exe that no external process holds the lock — it’s internal to the scanner. Redirecting sonar.working.directory and java.io.tmpdir doesn’t help.

Issue 2 — Bundled ESLint plugin deprecation

Every run also produces:

This comes from the scanner’s own bundled plugin configuration — nothing users can fix.

Impact: Both errors are cosmetic — analysis and quality gate work fine. However, they show as red errors in Azure DevOps logs and cannot be suppressed or downgraded from the pipeline side.

Ask: Could the temp folder deletion add a retry/delay, and the ESLint config be updated? Or at minimum, could these be logged as warnings instead of errors?

Issue 1: see ERROR: Failed to delete temp folder for dependency-files.tar.xz

Issue 2: which scanner (version) are you using? Have you installed eslint? In Please update eslint-plugin-sonarjs for ESlint 10 - #4 by victor.diez a version 4.0.0 was announced 2 weeks ago. And at eslint-plugin-sonarjs Installation we read “ensure that your project is configured with ESLint.”
