How to get badge to display

[tgsmith61591]

Hey, I used your coveralls wrapper on my java project and it worked seamlessly. Thank you so much! My question (and it's likely an extremely naive one...) is how to get the coverage badge? It seems like it didn't execute on coveralls.

Here is my repo. Here's what my .travis.yml file looks like:

language: java
jdk:
  - oraclejdk7

branches:
  only:
    - master

before_script:
 - "echo $JAVA_OPTS"
 - "export JAVA_OPTS=-Xmx512m"

after_failure:
  - cat target/surefire-reports/*.txt

before_cache:
  - rm -f $HOME/.gradle/caches/modules-2/modules-2.lock

cache:
  directories:
    - $HOME/.gradle/caches/
    - $HOME/.gradle/wrapper/

after_success:
- ./gradlew cobertura coveralls

And I have the following line at the head of my build.gradle:

plugins {
    // ... other plugins
    // coverage tools
    id 'net.saliman.cobertura' version '2.3.1'
    id 'com.github.kt3k.coveralls' version '2.6.3'
}
cobertura.coverageFormats = ['html', 'xml'] // coveralls plugin depends on xml format report

And yet, I'm still getting the coverage | unknown badge in my README. Any thoughts?

.travis.yml and the above part of build.gradle seem ok to me.

I looked at this build ( https://travis-ci.org/tgsmith61591/clust4j/builds/122092556 ) and ./gradlew cobertura coveralls seems failing at :test phase because of NoClassDefFoundErrors. (Try click $ ./gradlew cobertura coveralls part of travis console log).

Maybe classpaths are different when you test with coverage and without coverage.

Ah, you're absolutely right. I didn't even catch that portion of the log. After doing some digging around, it looks like there is a well-known issue with Cobertura causing these, though they profess it should have stopped in 2.3... There are also a lot of unanswered questions about this on StackOverflow. I'll keep digging around; if you have any ideas, I'd really appreciate your guidance.

I recommend you should try JaCoCo plugin instead of cobertura if it's difficult to debug.

Thanks, I went with JaCoCo and per this usecase, just sent the results to codecov with curl.
