Maven project : Java test classes should override main classes in classpath

[mrhydejc]

When running a test with maven surefire, the test classes override the main classes.

My project contains : src/main/java/AsyncConfig.java src/test/java/AsyncConfig.java

When running a test with maven, the classpath contains : src/test/java/AsyncConfig.java and succeed When running a test with VSCode test runner,, the classpath contains : src/main/java/AsyncConfig.java and failed

Is there a maven test runner for vscode ? Or a way to fix this classpath issue ?

This is an upstream issue caused by: https://bugs.eclipse.org/bugs/show_bug.cgi?id=498288

So far it's not allowed to contain same type name in different source sets.

Hi @mrhydejc, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions to address the classpath ordering in VS Code’s Java Test Runner:

• There’s no dedicated “Maven test runner” in the Java Test extension; it relies on the Java Language Server’s classpath, which currently merges test and main outputs and picks main classes first.

• Workaround: opening the test class in the editor can refresh diagnostics and sometimes correct the classpath at runtime (see below).

High-confidence references:

• Issue: Feature request to use separate output folders for main vs test • Problem: VS Code plugin puts both main & test classes in the same output folder, so test classes don’t override main ones • Status: Open feature request • URL: https://github.com/redhat-developer/vscode-java/issues/2312

• Issue: Overridden class in test package causes “type is already defined” error • Problem: Classes with the same name in src/main and src/test lead to errors; opening the test file in the editor clears the error • Workaround: open the test file before running to refresh the classpath • URL: https://github.com/redhat-developer/vscode-java/issues/1432
