How to get the exception that was thrown when a Cucumber test failed in Java?

Question

I can perform actions on test failure by using:

@After
public void afterTest(Scenario scenario) {
    if (scenario.isFailed()) {
        /*Do stuff*/
    }
}

If you just want to massage the result being sent to the report then you can extend the CucumberJSONFormatter and override the result method like this:

public class CustomReporter extends CucumberJSONFormatter {

    CustomReporter(Appendable out) {
        super(out);
    }

    /**
     * Truncate the error in the output to the testresult.json file.
     * @param result the error result
    */
    @Override
    void result(Result result) {
        String errorMessage = null;
        if (result.error) {
            errorMessage = "Error: " + truncateError(result.error);
        }
        Result myResult = new Result(result.status, result.duration, errorMessage);
        // Log the truncated error to the JSON report
        super.result(myResult);
    }
}

Then set the plugin option to:

plugin = ["com.myimpl.CustomReporter:build/reports/json/testresult.json"]
