[FIXED] Gradle jacoco multi project. How to output the code coverage of all the project in the terminal?

Issue

I am using Gradle jacoco plugin and have JUnit tests in a gradle multi project.

I have installed jacoco in order to report to sonarqube my code coverage, which I did.

Gitlab-CI also offer a badge for the code coverage, I only need to output the code coverage in a terminal and use a regex to find it.

Is there a way to output the code coverage of all the project in the terminal ?

Solution

Yes, you can. Possible ways:

1) Use Gradle plugin gradle-console-reporter to report various kinds of summaries to console. JUnit, JaCoCo and Cobertura reports are supported.

In your case, following output will be printed to console:

 ...
 BUILD SUCCESSFUL

 Total time: 4.912 secs

 Coverage summary:
 project1:                72.2%
 project2-with-long-name: 44.4%

Then you can use coverage with regular expression in Gitlab's .gitlab-ci.yml to parse code coverage.

2) Second option is a little bit tricky. You can print full JaCoCo HTML report (e.g. using cat target/site/jacoco/index.html) and then use regular expression (see this post) or grep (see this post) to parse coverage.
