IncompatibleClassChangeError running Cucumber tests in IntelliJ

When I run a cucumber test feature in IntelliJ, all it shows is an IncompatibleClassChangeError with stack trace: 

Testing started at 12:55 ...
/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin/java ...

This is IntelliJ IDEA 2018.1.4 (Ultimate Edition), Build #IU-181.5087.20, with Cucumber for Java version 181.5087.20

This is solved in the latest version.

You can recreate the configuration (so it will be updated automatically), or you can replace the program arguments with

--plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvm3SMFormatter

An older version of the plugin was not compatible with cucumber java version 3 and higher. If you are stuck with that one you can update your build.gradle to specify version 2 explicitly:

dependencies {
    ...
    testCompile 'io.cucumber:cucumber-java8:2.+'
}

As explained in issue #1392

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

The simplest workaround is removing --plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvm2SMFormatter from program arguments in the run configuration.
