I’m using SonarQube Ant task 2.7.0.1612. When I build and pint the scanner to the local community edition of SonarQube (version 8.1 build 31237), I see the coverage information without issue. However, when I point my scanner to the company SonarQube (version 5.6.3), the coverage does not display.
Is your company server really on 5.6.3? 5.6 is 4 years old, waaay past EOL and more than 2 LTSs out of date! I guess you’re not in charge of that server, but you might recommend to its admin an upgrade at earliest convenience.
As to your problem, I guess the parameters and recognized report formats have changed between then and now. Sorry, but without more details, it’s hard to be more precise than that.
