Specify locations to store the JaCoCo report execution data. From the Antrun plugin, define the reporting tasks.Configure the JaCoCo Ant task configuration process with the necessary information such as location of build, class, source or generated-source directories.Specify the Ant command from Maven using the Maven Antrun plugin.Create a submodule to append all results from JaCoCo using the Ant task.If specific modules don’t have to be included in the test coverage, change the plugin definition based on specific projects as required. The task objectives with this approach can be summarized as follows: Since the Maven JaCoCo plugin doesn’t support merging of subproject metrics into a single report file, a possible workaround solution is to use Ant with Maven. Some possible solutions are SonarQube, Jenkins, and Arquillian. You can use an additional tool to make up for this deficit. Make sure the module has access to the right files, and accurate location paths are included. Use this module to create dependencies to all the modules you need for your coverage report.

Maven users can also create a separate reporting module with dependencies. That probably won’t get you the whole way and may be a significant refactoring project.

One of the most obvious solutions is to avoid having a separate module for unit tests, rather including unit tests in the appropriate module. There are a number of possible solutions to address this challenge.

No matter what setup you run, JaCoCo won’t report code coverage well for integration tests that run across modules. Some projects are set up with unit tests in a separate module all by themselves, making the JaCoCo code coverage reports nearly useless. This can be an issue for multi-module projects where unit tests from one module test code in other modules. The JaCoCo plugin for Maven only reports code coverage for tests run in a particular module rather than reporting coverage across modules.
