Version 1.41.1 cannot resolve com.microsoft.java.test.plugin

[auberonedu]

When using Version 1.41.1, the VS Code test runner does not properly load when opening a new Java project. It instead says no tests found in the workplace and I get the below error in the output. Downgrading to 1.41.0 solves the issue.

I am using the Extension Pack for Java on Windows, but my students on a range of operating systems are also reporting issues with the test runner.

I am using a standalone JAR for JUnit in an unmanaged folder.

Expected behavior: Test runner shows tests
Actual behavior: Test runner says no tests found and prompts me to install testing extension.
Workaround: Downgrade to version 1.41.0

Same! Downgrading works. I hope this is fixed soon.

I teach an intro level CS course and we rely on JUnit. This will have a significant impact on our staff and students until it is resolved. I can also confirm rolling back to 1.41.0 obviates the issue.

See #3995 (comment)

Same situation, can confirm that downgrading to 1.41.0 helped

[jeff-nedley]

This definitely needs fixed ASAP. This is going to cause major setbacks and stress the longer it sits

[rgrunber]

The fix needs to happen at microsoft/vscode-java-test#1759 . Currently being held up waiting for jacoco to release a version compliant with latest ASM ( jacoco/jacoco#1862 ).

I can confirm this error on macOS and Linux. Test Runner for Java does not find tests in individual files. Test Explorer shows nothing. Downgrading Red Hat to 1.40.0 restored the capability for me.

[aarishgilani]

Can confirm downgrading worked on macOS. Test runner is unable to find test files in workspace. Spent
2 hours debugging this. Hope this gets fixed soon!

[cherking19]

Can confirm downgrading worked on Windows 11

Test Runner for Java (vscjava.vscode-java-test) pre-release 0.43.2025040304 is published with the fix, please install it and let me know if you still have the problem. Thank you!

[mbwhite]

@jdneo confirmed - updating to the pre-release version and I know have the test runner back and working again!

[andywarren86]

Issue has been resolved for me using Language support 1.41.1 & Test runner 0.43.2025040304.
