Sonarcloud shows wrong code coverage

[bodo-te-dv (Teichmann, Bodo- BRANDAD)]

Using Java, jacoco, maven, I got this coverage report for one file:

If you count the green lines , the red ones and the striped lines, you got:
red = uncovered = 7
striped = partly covered = 2
gree = covered = 14

now you calculate the coverage ratio:

covered+partly covered / all lines = 16 / 23 = 0.6956 = 70%
or
covered / all lines = 14 / 23 = 0.6086 = 61 %

But why does sonarcloud show a Coverage of 64,9% ?

• the Coverage HTML - Report above (same project, same files, same jacoco run) from Jacoco shows
  74% Instruction coverage and 57% Branch Coverage

• the Intellij Coverage plugin (using the same jacoco.xml report as sonarcube) shows
  69% line coverage (so it counts the partly covered lines also ) and
  57% Branch coverage

I understand that “line” coverage is different from “instruction” coverage.

But how comes that the sonarcloud shows this odd 64,9% , what kind of coverage is this ?

Unfortunately this, discrepancy in coverage is all over our whole project with hundreds of files,
the jacoco html- report and the sonarcloud coverage does not agree in most cases , why is that ?

SonarCloud combines line and condition coverage into a single coverage metric. You can read more about it here.

If you browse to the Measures tab of your project, you should be able to confirm that the individual metrics are what you expect.
