sbt-jacoco - Code Coverage via JaCoCo in sbt

Build Status Codacy Grade SBT 0.13 version SBT 1.0 version

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

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:
