Test runs successfully

Current Behavior

The following exception is thrown:

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found interface cucumber.api.TestCase, but class was expected

Possible causes

Here are some of the versions of the dependencies for the project. Maybe related?

        <spring.version>4.3.7.RELEASE</spring.version>
        <cucumber.version>3.0.2</cucumber.version>
        <junit.version>4.12</junit.version>
        <selenium.version>3.7.1</selenium.version>

Environment

Mac OS X
IntelliJIDEA

Apologies for not adding this earlier. I'm using a feature file that contains scenarios in gherkin. The scenario steps are linked to step definitions. All written in java using cucumber. The tests were all working fine when I was on Cucumber 2.1.0. However, when I upgraded to Cucumber 3.0.2, I got the error message mentioned above. I think it may be related to multiple choices of the same dependency or an interface becoming a class or vice versa. I have included a more expanded version of my pom file below:

This is caused by IDEA's CucumberJvm2SMFormatter. It being the formatter for Cucumber2, runs into a breaking change in Cucumber 3.

If you remove --plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvm2SMFormatter from program arguments in the run configuration it will work again. You'll have to do this until InteliJ fixes their plugin.

Many thanks, it works fine now

Please suggest, what is the mistake

@RajaRaviTeja Please don't comment on closed issues. If you want help using Cucumber, please try one of the support options.

[mlvandijk]

@RajaRaviTeja But to give a hint: Note that you are using both Junit and TestNG dependencies, and the testng dependency is a different version.
