Extended Description

Hi Team,

We generate the xml report for our project using gcovr( version 4.2) and clang (version 11.0)

We are facing the line endings issue. The xml file generated as part of the gcov and clang commands seems to contains more data than actual lines in the file. Sonarqube-scanner is not able to find the lines mentioned in the xml and hence fails the build.

We tried to fix the line endings issue by:

.gitattributes approach to fix the line endings but no luck

checked if it contains multiple files with same name and the answer is No

there are no old gcno/gcna files available in the workspace

After addition of warnings in the gcovr, we get the below output/warnings:

Command use for xml generation:

python -m gcovr --gcov-executable="llvm-cov gcov" -v --root /var/jenkins/0/workspace/_feature_align-coverage-metrics2 --branches -f '/var/jenkins/0/workspace/_feature_align-coverage-metrics2/build/unittest-clang/BRC36xx-5/Debug/(src|include)/' -f '/var/jenkins/0/workspace/_feature_align-coverage-metrics2/src/(src|include)/' --object-dir=. --exclude-directories '/var/jenkins/0/workspace/_feature_align-coverage-metrics2/build/unittest-gcc/' --html-details=gcovreport/index.html --sonarqube=gcovreport/sonarqube.xml
