How to Fix: Maven Jacoco Configuration - Exclude classes/packages from report not working
Exclude specific classes or packages from Jacoco code coverage reports in a Maven multi-module project.
📋 Table of Contents
In Maven Jacoco configuration, the <exclude> element is used to exclude classes or packages from the code coverage report. However, if you are using a multi-module project and trying to exclude certain classes or packages that are present in only one of the modules, the <exclude> element may not work as expected.
🔍 Why This Happens
- The <exclude> element only works when the class or package is present in the current module, but not in any of its sub-modules.
✅ Best Solutions to Fix It
Method 1: Use the <excludes> Element
- Step 1: Instead of using the <exclude> element, use the <excludes> element to specify the packages or classes that you want to exclude.
Method 2: Use the <configuration> Element and Specify the Exclude Pattern
- Step 1: In the <configuration> element, specify the exclude pattern using the format 'some.package.*' or 'some.package.subpackage.*'.
🎯 Final Words
By following these methods, you should be able to exclude classes or packages from your Maven Jacoco report correctly.
