We have tried doing multiple things but all in vain. Any help would be greatly appreciated!

Hello, I also encountered this problem. Have you solved this problem?

Hi @saioncorp ,

It seems like you are using a newer version of the build-wrapper (6.17) with an old version of the plugin. Where are you downloading the build-wrapper from? You should always download the build-wrapper from your SonarQube server to make sue you are using the correct version.
