Imported coverage data for 0 files

(Gash Teshome) #1

When running code coverage analysis on our CI/CD platform (Jenkins worker on macOS) a Swift iOS app, sonar-scanner does not import coverage data with the message

Imported coverage data for 0 files

The same analysis works on developer workstations that are using the same version of sonar-scanner, Java, and OS. I am looking for troubleshooting pointers on how to determine why the same coverage analysis is behaving differently on different systems.

Must-share information (formatted with Markdown):

  • which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
    SonarQube: 7.7 Developer Edition
    SonarSwift plugin: 4.1 (build 3087)
    Java: Java 1.8.0_212 AdoptOpenJDK (64-bit)
    OS: Mac OS X 10.14.3 x86_64
  • what are you trying to achieve
    Code coverage analysis
  • what have you tried so far to achieve this
    We followed the instructions on sonar-scanner fails to import coverage data with the sonar-coverage-example code as well as our iOS application. The full output of the analysis for sonar-coverage-example is below. I can also provide the output for a successful analysis, if needed.

You stopped reading just a little bit early. :slight_smile:

Just after the line you quote, is the crux:

Your generic test coverage report gives coverage data for files the analysis doesn’t recognize. Are you sure these paths are correct? Also, the third file listed appears itself to be a test. Since you can’t have coverage of tests, that one should probably be dropped from the report.

The files are definitely there:

 ls -l /var/jenkins/src/sonar-scanning-examples/swift-coverage/swift-coverage-example/swift-coverage-exampleTests/swift_coverage_exampleTests.swift 
-rw-r--r--  1 jenkins  wheel  959 May  8 17:15 /var/jenkins/src/sonar-scanning-examples/swift-coverage/swift-coverage-example/swift-coverage-exampleTests/swift_coverage_exampleTests.swift
ls -l /var/jenkins/src/sonar-scanning-examples/swift-coverage/swift-coverage-example/swift-coverage-example/AppDelegate.swift
-rw-r--r--  1 jenkins  wheel  700 May  8 17:15 /var/jenkins/src/sonar-scanning-examples/swift-coverage/swift-coverage-example/swift-coverage-example/AppDelegate.swift
ls -l /var/jenkins/src/sonar-scanning-examples/swift-coverage/swift-coverage-example/swift-coverage-example/AppDelegate2.swift 
-rw-r--r--  1 jenkins  wheel  298 May  8 17:15 /var/jenkins/src/sonar-scanning-examples/swift-coverage/swift-coverage-example/swift-coverage-example/AppDelegate2.swift

I had seen the message about about sonar-scanner not recognizing the files but that is another point where I am confused. If I take the same code and run it on another system with the same versions of sonar-scanner, Java, and OS, the analysis completes successfully.

Are there further troubleshooting steps I can take to see what’s happening in more detail with the analysis? I see that there’s a .scannerwork directory, as well as ~/.sonar/. Is there anything in either directory I can look to understand what’s happening during analysis?

-Dsonar.verbose=true might help.
