While reworking a project in Intellij into modules, i came across this error:

Error: Could not find or load main class cucumber.cli.Main
I later found out that the Run configuration was wrong due to the refactoring and then defaulted, thus causing an error.
The way I fixed it was to delete all configurations (drop down in top right of image) and also remove cucumber java by selecting and clicking the "-"
Then I right clicked on the Main application i wanted to run and selected run, or ctrl + shift + F10 for the short cut.
