How can we exclude method from JaCoCo Code coverate

[Irene Chai]

Hi,

From https://stackoverflow.com/questions/47824761/how-would-i-add-an-annotation-to-exclude-a-method-from-a-jacoco-code-coverage-re

Looks like
@ExcludeFromCodeCoverage is supported on JacCoCo 0.8.2+

But when we add it, we got build failures.

Is any other annotation supported to exclude a method/function from code coverage report in Java ?

Thanks

IR

[Marc Hoffmann]

Can you please post the full error message of the build failure?

Thx,

-marc

Well you actually need to declare that annotation in your code base. For example:

@Retention(RetentionPolicy.CLASS)

public @interface ExcludeFromCodeCoverage {

}

Thanks Marc !

Does  JaCoCo report will skip the method from code coverage if this annotation "ExcludeFromCodeCoverage"  ?

[Irene Chai]

What we want is to achieve is to skip some methods from code coverage reports.

Thanks

Actually not. My bad. Only annotations that contain the string “Generated” will make the methods disappear from the coverage report.
