• oss repo: https://github.com/alkal-io/kalium
• using Travis
• jacoco

Customer using jacoco and couldn't figure out how to set it up. They were able to point it to the xml file. But then it complaints about the source.

• Travis.yml here

• gradlew: https://github.com/alkal-io/kalium/blob/master/gradlew

• Travis output: https://travis-ci.org/alkal-io/kalium/jobs/531032809

See the callout on using JaCoCo at https://docs.codeclimate.com/docs/configuring-test-coverage
and also #259 (comment)

@rhwood I am facing the same issue. I followed the documentation and used alternate command.

$ echo "Step Name - after_script"
$ JACOCO_SOURCE_PATH=report/src/main/java ./cc-test-reporter -d format-coverage ./report/target/site/jacoco-aggregate/jacoco.xml --input-type jacoco

      --add-prefix string   add this prefix to file paths
  -t, --input-type string   type of input source to use [clover, cobertura, coverage.py, excoveralls, gcov, gocov, jacoco, lcov, simplecov, xccov]
  -o, --output string       output path (default "coverage/codeclimate.json")
  -p, --prefix string       the root directory where the coverage analysis was performed (default "/home/travis/build/WW-Digital/wcp-broadleaf")

      --insecure          send coverage insecurely (without HTTPS)

There are multiple modules in the project and an aggregate jacoco.xml file is generated. But rest-reporter is not able to find it.
Though the build is running in TravisCI but when I run the build in my local than I get almost 3.49MB file jacoco.xml at report/target/site/jacoco-aggregate/. I am pretty sure the file is there.
There are 4 files at report/target/site/jacoco-aggregate/:

index.html
jacoco.csv
jacoco.xml
jacoco-sessions.html

@efueger did you find any solution to this issue. Pls share.
