IllegalStateException Unable to read plugin manifest from sonar-detekt-plugin.jar

[abhivaikar]

What Sonarqube version I'm using
Using SonarQube community edition 8.9.8 (build 54436)

What am I trying to achieve

• Run sonar scanner as part of a travis build for golang based project.
• The travis build config script has cache enabled for sonar plugins that get downloaded every time from the sonarqube server.

cache:
  directories:
  - $HOME/.sonar/cache

What issue am I facing?
Things were working fine for many days until today when a build failed due to below error

Any idea why this might be happening? Thanks for any help in advance.
