sonar swift plugin exception java.nio.charset.MalformedInputException: Input length = 1

[Rishi Goel]

I am testing out the sonar swift plugin for our project which uses a mix of objC and swift. I am doing the following:

1. Run unit tests

2. Use xcodebuild with -showBuildSettings to generate build-settings.txt file which contains the PROJECT_TEMP_DIR path

3. Use the commands below to get the location of coverage.profdata file and the app binary

     PROJECT_TEMP_ROOT=$(grep -m1 PROJECT_TEMP_ROOT ${BUILD_SETTINGS} | cut -d= -f2 | xargs)

     PROFDATA=$(find ${PROJECT_TEMP_ROOT}/CodeCoverage -name "Coverage.profdata")

     BINARY=$(find ${PROJECT_TEMP_ROOT}/CodeCoverage -path "*xyz.app/xyz")

4. execute xcrun llvm-cov show -instr-profile=${PROFDATA} ${BINARY} > codecoverage.report to generate the codecoverage report fie.

5. I am running build wrapper which generates a json file and give the path of the json file in the sonar-project.properties using sonar.cfamily.build-wrapper-output property

6. run sonar-scanner -e

Our unit tests have a mix of objC and swift language so the codecoverage.report file also has a mix of objC and swift info.

When I run sonar-scanner -e, I get this exception:

ERROR: Can't open coverage report file. No coverage information will be saved.

I tried commenting out the sonar.language property but no luck.

Hello,

Which version of SonarSwift do you use?

This problem was fixed in SonarSwift 2.1 (ticket https://jira.sonarsource.com/browse/SONARSWIFT-287)

Hi Elena,

Thank you. SonarSwift 2.1 worked for me, I used SonarSwift 2.0 previously.

However in unit test, I have nothing displayed.

Attached screenshot, kindly advise.

Hello,

For further questions please contact commercial support.

Thanks
