Hi,
    Did they provide you with the new URL pattern? It looks like that even in the SonarSource repo they are still using the old URL (search for quality gate):

     https://raw.githubusercontent.com/SonarSource/sonar-java/master/README.md The new URL's are provided on the sonarcloud.io project page. The options

https://sonarcloud.io/api/project_badges/measure?project=com.iluwatar%3Ajava-design-patterns&metric=alert_status
https://sonarcloud.io/api/project_badges/quality_gate?project=com.iluwatar%3Ajava-design-patterns

SonarCloud badge URL changing
Hi,

About a month ago, we deployed new built-in badges on SonarCloud: 
News: https://about.sonarcloud.io/news/2018/02/05/new-project-badges.html
Tweet: https://twitter.com/sonarcloud/status/960790516936867840
As explained in the news, the URL for those new badges is different from the old one - which we will remove on Monday April, 2nd (so in a month from now).

I'm contacting you because we noticed that some of the projects you are admin of might still be referencing the deprecated badge URL ("/api/badges/..."). If this is not the case, please ignore this email - what we see in our logs might come from forks of your repositories. However, if some of your projects do still use those deprecated URL, you might want to update them in the upcoming month to keep on enjoying SonarCloud badges on your projects. 

Hope you enjoy the service!

Best regards,
