I'm trying to use the Jacoco code coverage to get a coverage report for this test I made with TestNG. The settings should be right, but I get an error and the report is showing no coverage. What could be the issue?

Hi,

Which version of IDEA are you using?

I've tried a Maven project with JDK 23, and it worked with Jacoco by switching to it via the menu File | Settings | Build, Execution, Deployment | Coverage.

Please upload the sample project to https://uploads.jetbrains.com/ and paste the upload ID here.

Ok I figured it out. My IDEA wasn't updated. Jacoco works fine now.
