Mission

JaCoCo should become the standard backend technology for code coverage analysis in Java VM based environments. The focus is providing a lightweight, flexible and well documented library for integration with various build and development tools.

There are several open source coverage technologies for Java available. While implementing the Eclipse plug-in EclEmma the observation was that none of them are really designed for integration. Most of them are specifically fit to a particular tool (Ant tasks, command line, IDE plug-in) and do not offer a documented API that allows embedding in different contexts. One of the best and widely used available open source tools is EMMA. While EclEmma is based on it the EMMA library is not actively maintained any more by the original author. Due to the lack of regression tests maintenance and feature additions will become very difficult.

JaCoCo should become the standard backend technology for code coverage analysis in Java VM based environments. The focus is providing a lightweight, flexible and well documented library for integration with various build and development tools. Ant tasks, a Maven plug-in and the EclEmma Eclipse plug-in are provided as reference usage scenarios.
