Modified the original script from cover2cover to include support for different file types (not just Java). For example, I work on a project that is predominantly Kotlin and I need to be able to provide coverage for our Kotlin files. However, my modification defaults a class to Java if a Class isn't found in the pool of Source Files. Feel free to open up any issues you encounter, as well as fork this repo. Your feedback is celebrated and greatly appreciated!
A script for converting JaCoCo XML coverage reports into Cobertura XML coverage reports.
I created this script because I wanted code coverage reports in Jenkins[1]. Since Cobertura[2] doesn't support Java 1.7 or higher (the project seems abandoned), we had to use JaCoCo[3], which is great coverage tool and very easy to use.
However, the Jenkins JaCoCo plugin[4] leaves a lot to be desired, while Cobertura's Jenkins plugin[5] is a lot better. To be precise, it supports:
- Trend graphs for packages, classes, etc. instead of just lines
- Trend graphs in percentages instead of absolute numbers
- High and low "water marks" that cause the build to become unstable in Jenkins
Until the JaCoCo plugin is up to speed, this script can be used to convert JaCoCo XML reports into Cobertura XML reports, so we can continue to use the Cobertura Jenkins plugin to track coverage.
Not every feature is supported, but close enough.
Add the following "post step" to your Jenkins build:
mkdir -p target/site/cobertura && cover2cover.py target/site/jacoco/jacoco.xml src/main/java > target/site/cobertura/coverage.xml
And add the Cobertura plugin with the following path:
**/target/site/cobertura/coverage.xml
(Note: The above assumes a Maven project)
