Build shows test coverage but Badge says Coverage unknown

Hi, i have setup showing Test Coverage for a Gitlab Project build with Maven and Junit. I did it like described in this article

The build shows the test coverage but the link to the badge says the coverage is unknown. Do someone knows what the problem can be ?

Did you fix it? Have the same issue :frowning:

Hi, problem was that tests did not run on master branch, please check your gitlab ci config.

Best Regards
