After having spent some time trying to migrate my Message Coboy project from Maven to Gradle, I finally gave up. I guess Gradle is not for me and I do not see any significant gains in moving from Maven to Gradle, neither as far as my sparetime projects are concerned nor in the organization where I work.
The reason for me wanting to migrate to Gradle was not really Gradle in itself, but the cool badges with code coverage, download latest release etc that I saw on the Mockito project.
Fortunately there is a very nice Coveralls Maven plug-in with excellent documentation which I can recommend.
So what were the required modifications?
First I added the Cobertura and Coveralls plug-ins to the <build> section of my pom.xml:
<!-- Generates code coverage report. -->
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.6</version>
<configuration>
<format>xml</format>
<maxmem>256m</maxmem>
</configuration>
</plugin>
<!-- Submit code coverage report to Coveralls.io. -->
<plugin>
<groupId>org.eluder.coveralls</groupId>
<artifactId>coveralls-maven-plugin</artifactId>
<version>3.0.1</version>
<configuration>
<!-- Since I use Travis CI I do not have to put my Coveralls token here. -->
</configuration>
</plugin>
</plugins>
</build>
Second I added two lines in the .travis.yml file. The new version of the file looks like this:
language: java jdk: - oraclejdk7 after_success: - mvn clean cobertura:cobertura coveralls:report
Finally I signed up for Coveralls, which is free for all open-soruce projects, and copy-pasted the markup that displays the code coverage badge to the Message Cowboy ReadMe.md file.
Many thanks to the developer of the Coveralls Maven plug-in and to the generous folks at Coveralls!
