Sonarqube "Failed to create an empty directory" when scanning multiple projects in one VSTS build definition

Question

I need to run sonarqube for multiple projects in a nightly build definition. The problem I found is - after successfully run sonarqube for the first project, a .sonarqube folder is created and a process seems keep using the folder. As a result, the folder cannot be deleted / used by subsequent projects. Is there a way to solve this?

Error in the prepare step of 2nd project:

Answer 1

I bypass this issue:

• by adding a delete file task to pipeline before "Prepare analysis on SonarQube" task;
• delete ".sonarqube\out\" folder. Source folder "$(Agent.BuildDirectory)\.sonarqube\out\";
• be sure to check "Remove files starting with a dot" in advance.
