I have com.github.xxxxxx:xxxxxx Maven repository and I want add shields badge but I have a invalid badge:
https://img.shields.io/sonar/https/sonarqube.com/com.github.nor
Update for June 2018 ...
API was deprecated early 2018 and removed in April 2018.
Currently there's a link on a project's lower RHS, "Get project badges", which reveals available image urls for metrics.
