Question

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

Error: Could not find or load main class cucumber.cli.Main

Answer 1

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.

Answer 2

I think I found a solution. By adding below dependency to pom.xml will clear above exception

<!-- https://mvnrepository.com/artifact/io.cucumber/cucumber-java -->
<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-java</artifactId>
    <version>5.7.0</version>
</dependency>

Answer 3

For me, it turned out that I opened as a project the parent directory of the actual main project directory. When I opened the correct project directory in IntelliJ, that had the "src" folder as a direct subfolder, cucumber worked. For reference, see instructions here: https://www.jetbrains.com/help/idea/enabling-cucumber-support-in-project.html#folder-structure, and a similar StackOverflow thread here: Intellij IDEA Run configurations for Cucumber runner class .
