How to scan when we have multiple lcov.info files in a UI project

SonarQube
,
#1
  • which versions are you using : SonarQube 8
  • what are you trying to achieve: I am having multiple angular library projects, and each of them are run separately for the code coverage. So the coverage paths look like this
    reports/coverage/**/lcov.info

The ** I put because I have multiple folders each for my angular libraries.

How can I make sonar scan multiple lcov.info files

sonar.javascript.lcov.reportPaths=$(System.DefaultWorkingDirectory)/$(ProjectFolder)/reports/coverage/**/lcov.info

Above is what I tried. But then the scanner says it can not find any lcov.info

Hi @mukund26 ,

Welcome to SonarSource Community! :sonarsource:

Are you using SonarQube 4? Please upgrade to the latest version of SonarQube and try again. Yes, SonarQube can handle multiple lcov.info files. If it fails again, please run Sonar scanner analysis with sonar.verbose=true analysis parameer and share logs here.

Sorry. I was using sonar server 8.9
The azure devops yml task version I was using was 4. The verbose mode logs are here.

When I use the ** wildcard, this is what I get

Hi @mukund26 ,

Can you try setting sonar.javascript.lcov.reportPaths=**/lcov.info instead?

Also, is your project a mono-repo?

#6

I get this then

Provided LCOV file path: **\lcov.info. Seek file with path: D:\work\75\s**\lcov.info

08:45:31.030 WARN: No coverage information will be saved because all LCOV files cannot be found.

#7

My project is a monorepo. With several angular libraries. The PR decoration for the sonar is also not working.

#8

Does anyone has any idea about this?

Hi @mukund26 ,

I think you have run into this issue: Support wildcards for coverage report paths · Issue #578 · SonarSource/SonarJS · GitHub Please confirm if this is the case. This issue will be fixed in SonarJS 8.3, which will release in SonarQube 9.1.

#10

We are using sonar server 8.9.1. When can we expect 9.1?

#11

It is planned for late-September 2021.

#12

You can simply use this command to merge multiple lcov.info files into one until this feature is live:

npm test (part1)
cd coverage && mv lcov.info lcov_1.info
npm test (part2)
cd coverage && mv lcov.info lcov_2.info
npx lcov-result-merger 'coverage/lcov_*.info' 'coverage/lcov.info'
