Hi All I have setup the most simplest test class:

import static com.github.tomakehurst.wiremock.core.WireMockConfiguration.wireMockConfig;

import com.github.tomakehurst.wiremock.WireMockServer;

public class WireMockStandaloneTest {
    public static void main(String[] args) {
        WireMockServer wireMockServer = new WireMockServer(wireMockConfig().port(8080));
        wireMockServer.start();
        System.out.println("WireMockServer started on port: " + wireMockServer.port());
        wireMockServer.stop();
    }
}

When I run the "app" I receive this error:

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index 0 out of bounds for length 0

The maven dependency I am using:

<dependency>
