Failed to find jacoco.xml

[ham1]

We have a Maven project which creates a jacoco.xml file in target/site/jacoco/ but when running ./cc-test-reporter after-build it says

Error: not find any viable formatter. available formatters: simplecov, lcov, coverage.py, clover, gocov, gcov, cobertura, jacoco

Running with ./cc-test-reporter after-build -d -t jacoco gives:

DEBU[0000] about to run format-coverage
DEBU[0000] using formatter jacoco
DEBU[0000] checking search path for jacoco formatter

The commands above were run from the roof of the project, the dir structure after a test run looks like:

tree -d -L 2
.
├── doc
│   └── style
├── logs
├── src
│   ├── main
│   └── test
└── target
    ├── classes
    ├── generated-sources

    └── test-classes

We have this problem too. I managed to get around it by copying the jacoco.xml file from ./target/site/jacoco/jacoco.xml to ./src/main/java/jacoco.xml and then running cc-test-reporter from inside ./src/main/java/.

The CLI help for cc-test-reporter looks like you can give it PATH prefixes but I could not get any of them to work.

Obviously this is not a nice solution but could be helpful while this tool matures.

Summary

cp target/site/jacoco/jacoco.xml src/main/java/jacoco.xml
cd src/main/java/
../../../../cc-test-reporter after-build -d -t jacoco

Thanks for the workaround, it would be nice to have this fixed, unless I'm doing something wrong?

@ham1 I'm having the same issue. For reference, here's my project: https://github.com/magneticflux-/kotlin-simplexml-rss/pull/1.

EDIT:
This was how I solved my issue:

after_script:
  - mv "build/reports/jacoco/test/jacocoTestReport.xml" "src/main/kotlin/jacoco.xml"
  - cd src/main/kotlin/
  - ../../../cc-test-reporter after-build -t jacoco --exit-code $TRAVIS_TEST_RESULT

It appears that the -p flag is completely ignored.

Same problem here with a Gradle project at Jenkins. Solved it with this other workaround:

cd src/main/java
test-reporter-latest-linux-amd64 format-coverage -t jacoco ../../../build/reports/jacoco/test/jacocoTestReport.xml
test-reporter-latest-linux-amd64 upload-coverage -r ID

It would be nice to have the format-coverage and upload-coverage documented in the help, along with the prefix option fixed.

PD: Does anyone know what's the purpose of the before-build command?
