vscode generates compile errors for valid test-jar dependencies

I have a non shipping "utility" maven module. It has a dependency on classes from a test-jar produced by another module. If both the utility maven module and the test-jar producing module are loaded in the workspace, vscode generates compile errors for all imported test-jar classes. See the first screenshot below. Note that the compile errors in vscode are incorrect and should not exist. In contrast, running "mvn clean install" results in a successful build and IntelliJ handles this situation fine (there are no compile errors).

If however the module that produces the test jar is not loaded in the workspace, there are no compile errors for the imported test-jar classes in vscode. See the second screenshot below. In otherwords, the compile error only shows up when the test-jar producing module is in the workspace with the test-jar consuming module. Apparently vscode/eclipse jdt cannot resolve the test classes when they are from a local project and imported by another project's src/main classes.

I will attach 2 small maven projects to demonstrate the problem. You can load them into vscode to reproduce. You can also build them from the command line with mvn to confirm they are valid.

Compile error when both test-jar consuming and producing projects are in the workspace

No compile error when the test-jar producing project is not in the workspace

test-jar-issue-projects.zip

Bắt đầu bằng cách mở test-jar-issue-projects.zip trong VS Code với cả hai dự án Maven được tải, sau đó so sánh các chẩn đoán với một workspace chỉ chứa dự án sử dụng. Chạy mvn clean install để xác nhận các dự án hợp lệ; công việc được hoàn tất khi các import test-jar cục bộ không còn tạo ra các lỗi biên dịch giả khi cả hai dự án đều hiện diện.
