This is an sbt plugin for code coverage analysis via JaCoCo. Supports uploading results to Coveralls, Codecov and Codacy.

Install the plugin by adding the following to project/plugins.sbt:

addSbtPlugin("com.github.sbt" % "sbt-jacoco" % "<version>")

And then execute the plugin with sbt jacoco. This will instrument and run the unit tests and output the coverage metrics:
