Cannot 'run all tests...' anymore

Hi,

I have been frequently running all the tests in a package/directory by right clicking the directory or module and selecting 'Run all tests'. At some point though this has stopped working - intellij simply reports '0 test class found in package...'.
Its something thats happened to this one project. If I create a new maven module in the same project, I'll have the same problem - but if I create a new project and add a new maven module, it works.

If I run 'mvn install' my tests run fine.

Anyone have any suggestions how I debug and fix this?

Thanks.

Hello Paul,

Please try to invalidate caches (https://www.jetbrains.com/idea/webhelp/cleaning-system-cache.html) and reimport your project. If it doesn't help please attach idea.log ("Help - Show Log in...") after reproducing the issue.

Thanks, invalidating caches and restarting was the first thing I tried - it didn't help.
I have created a new project and imported the same modules and it was working okay until I modified my run config - I removed 'make' and add a 'maven install' to try something out. After I did that, I could never (from any run config) get it to find tests. I removed the maven target and put 'make' back in but it didn't help. Creating a new project was the only thing I could find that would help.

I will try this again on a trivial maven project and post the log.

Thanks.

Hi,

I've tried this on a trivial maven project in IDEA 13.1.2 on MacOs and so far I haven't been able to reproduce the problem.

I think it must be something to do with the way the project poms are set up - there's all sorts of customisations around the testing and a chain of parent poms so I'll dig through that.
I'm not convinced its a problem with Intellij.

Are the run configurations influenced at all by the maven pom configuration?

Thanks.

Paul,

I'll need idea.log to investigate the issue. Also it would be great if you could attach sample project describing the problem.

Had the same issue with my project. Fixed by removing .idea package from the project and open it as a new one from existing source

Invalidating Caches solved the problem for a few seconds, and than the menu-entries disappeard again. Running IntelliJ IDEA 2025.3.1.1

Hi Tonino Ferrara, Thank you for your feedback.

I could not reproduce the issue on my side using IntelliJ IDEA 2025.3.1.1. 
Could you please try to perform the following steps to resolve this problem:

  1. Close your project (File → Close Project);
  2. Close all instances of IntelliJ IDEA;
  3. Rename or remove the System Directory;
  4. Run IDEA and re-import the Project: Open → Navigate to the Project's directory → Double-click the root pom.xml → Open as Project

After that check if it works correctly. If not, please collect IDE logs via Help | Collect Logs and Diagnostic Data after reproducing this issue and upload them to our server https://uploads.jetbrains.com/ and provide us with the Upload ID. The uploaded data will be accessible only to our team and will be used solely for investigating this issue. Thank you!

I deleted the System Directory, but that did not help. I uploaded the requested files: 2026_01_12_G5W38YcTUW98q8H3pAP8zx

Tonino Ferrara, thank you!
Unfortunately, the idea.log file from the provided logs is empty.
Could you please reproduce this issue again and then collect IDE logs via Help | Collect Logs and Diagnostic Data?
After that please create a new ticket using this link and provide new Upload ID to log files there. We will investigate your report individually.

We appreciate your understanding!
