Command Line Interface

JaCoCo comes with a command line interface to perform basic operations from the command line. The command line tools with all dependencies are packaged in jacococli.jar and are available with the JaCoCo download. Java 1.5 or greater is required for execution.

For more sophisticated usage especially with larger projects please use our integrations with various build tools.

The following commands are available. Each command has a list of optional and required parameters. Some parameters can be specified multiple times to provide multiple values.

Warning: Although a instrument command is provided the preferred way for code coverage analysis with JaCoCo is on-the-fly instrumentation with the JaCoCo agent. Offline instrumentation has several drawbacks and should only be used if a specific scenario explicitly requires this mode. Please consult documentation about offline instrumentation before using this mode.
