jacoco code coverage report generator showing error : “Classes in bundle 'Code Coverage Report' do no match with execution data”

Question

I am generating jacoco report by using jacoco:report tag. I am getting errors like :

[jacoco:report] Classes in bundle \'Code Coverage Report\' do no match          


        

Answer 1

JaCoCo needs the exact same class files for report generation that used at execution time. Due to different compilers and/or other tools modifying the classes, the classes might be different.
