Run code coverage with Intellij

[Frank]

Has anyone has success make the "Run with Coverage" work for pants projects in Intellij? I am using latest version of IntelliJ with latest pants plugin but it would always fail.

I am able to run pants command line for code coverage successfully with: "./pants clean-all test backend: --test-junit-coverage-open". In the same time I am able to run junit tests within Intellij for my pants projects.

But when I do "Run with Coverage" for junit tests within Intellij, it runs tests successfully, then a dialog pops up with "Project is out of date" title, if I click "cancel" then nothing happens, if I click "OK" then it opens the Coverage tab, right after that it prints exception message like below and no coverage information will be given:

Any idea on how to fix this? This would be really helpful for me to see what's not covered right within IntelliJ.

Thanks,

Frank
