I'm working on a Gradle plugin (https://github.com/mkobit/jenkins-pipeline-shared-libraries-gradle-plugin) that makes it simple to build and test Jenkins Shared Libraries. Jenkins Shared Libraries operate on source code instead of compiled code. Jenkins itself embeds Groovy for compilation of various pipeline scripts. It performs some manipulations before execution. The code that comes out seems to be deterministic from what I can tell.
I am trying to figure out a way to coverage for these source Groovy files when they are compiled and executed in a Jenkins runtime. I've documented my journey so far in https://github.com/mkobit/jenkins-pipeline-shared-libraries-gradle-plugin/issues/32 but here is a summary of where I am currently at: * I can get execution data for the classes * Dumping classpath shows multiple instances of the library classes (1 per test they are used in) * Attempting to get a report fails with `java.lang.IllegalStateException: Can't add different class with same name: com/mkobit/libraryexample/ExampleSrc`. There are a few other duplicates as well * Filtering down the report to only a single specific file allows me to generate a coverage report, but I only get it for the test was filtered (https://github.com/mkobit/jenkins-pipeline-shared-libraries-gradle-plugin/issues/32#issuecomment-366371128) What I want to try and figure out is, what is the right way forward to "merge" the execution data together for the original source file? It sounds similar-ish to https://github.com/jacoco/jacoco/issues/197 so I'll add a comment there as well. Here are some reproduction steps: 1. `git clone -b 'mk/coverage-investigation' https://github.com/mkobit/jenkins-pipeline-shared-library-example.git` 2. `cd jenkins-pipeline-shared-library-example` 3. `./gradlew integrationTest jacocoIntegrationTestReport -s ==> See error mentioned above about duplicate classnames 4. `find build/jacoco/classpathdumps/com/mkobit/libraryexample/ExampleSrc.* | head -n 1 | xargs -n 1 basename` ==> this will get one of the classes. for me this time, it was "ExampleSrc.99203068b63d74ec.class" 5. Replace the class name at https://github.com/mkobit/jenkins-pipeline-shared-library-example/blob/6d268d56c86c626312bc76a9e00051c5749c28d1/build.gradle.kts#L52 with the class name above and uncomment the line 6. `./gradlew jacocoIntegrationTestReport` ==> Generate report for single class 7. Open HTML report at build/reports/jacoco/jacocoIntegrationTestReport/html/index.html and see results for class 8. find build/jacoco/classpathdumps/com/mkobit/libraryexample/ExampleSrc.* | tail -n 1 | xargs -n 1 basename ==> get name for other class 9. Repeat steps 4-7 with result from other class to see different -- You received this message because you are subscribed to the Google Groups "JaCoCo and EclEmma Users" group.
