Kotlin app 0% code coverage?

[arne.riiber]

We rewrote an app from Java to Kotlin, and now Sonar says 0% code coverage for the app, while Jacoco HTML says 58%. Any ideas on how to resolve?

• ALM used: GitLab
• CI system used: Jenkins
• Scanner command used when applicable: ./gradlew -DtestBuildType=debug app:jacocoTestReport; ./gradlew sonar
• apply plugin: “org.sonarqube”
  sonar {
  properties {
  property “sonar.projectKey”, “…”
  property “sonar.organization”, “…”
  property “sonar.host.url”, “https://sonarcloud.io”
  property “sonar.c.file.suffixes”, “-”
  property “sonar.cpp.file.suffixes”, “-”
  property “sonar.objc.file.suffixes”, “-”
  property “sonar.coverage.jacoco.xmlReportPaths”, “build/reports/jacoco.xml”
  }
  }
• Languages of the repository: Android Java, Kotlin

Version of Gradle plugins:

• org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:4.0.0.2929
• org.jacoco:org.jacoco.core:0.8.8

Thanks
Best regards

Hi Arne,

Welcome to the community!

Can you post your analysis log?

The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.

This guide will help you find them.

Hi G. Ann, sorry for late reply caused by vacation & funeral.

This week we found out the reason why we got 0% coverage of the Kotlin Android app, the class path is different for Java and Kotlin:

• Java: “${buildDir}/intermediates/javac/debug/classes”
• Kotlin: “${buildDir}/tmp/kotlin-classes/debug”

After adding the class path for Kotlin as above, got code coverage. So issue is resolved now, thanks.

Best regards,
Arne
