JNI-error occuring when trying to start BrowserMobProxyServer in Embedded Mode (Java, Maven)

Hey guys my first post here.. I'm trying to setup Selenium and Browsermob Proxy in Java in Embedded Mode (gotta to say that I never used Maven, Selenium or BrowserMob Proxy before). Following the Github instructions of BrowserMob Proxy I set up a Maven-Project in Eclipse and added both dependencies in pom.xml.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.ba</groupId>
<artifactId>com.ba.project</artifactId>
<version>0.0.1-SNAPSHOT</version>

<dependencies>
    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.14.0</version>
    </dependency>

<dependency>
    <groupId>net.lightbody.bmp</groupId>
    <artifactId>browsermob-core</artifactId>
    <version>2.1.5</version>
    <scope>test</scope>
</dependency>
</dependencies>

In order to test whether it works...

public class Test {
public static void main(String[] args) {
    System.setProperty("webdriver.gecko.driver", "...");
    WebDriver driver = new FirefoxDriver();
    BrowserMobProxy proxy = new BrowserMobProxyServer();
    proxy.start(0);
}}

... I get this errordialog followed by this exception..

Exception in thread "main" java.lang.NoClassDefFoundError: net/lightbody/bmp/BrowserMobProxy

When I remove the last to lines from the main method it works without problems. Does anyone has an idea what I'm doing wrong here? Thanks in advance.

Can you replace

<dependency>
    <groupId>net.lightbody.bmp</groupId>
    <artifactId>browsermob-core</artifactId>
    <version>2.1.5</version>
    <scope>test</scope>
</dependency>

with

<dependency>
    <groupId>net.lightbody.bmp</groupId>
    <artifactId>browsermob-core</artifactId>
    <version>2.1.5</version>
</dependency>

and give it a try? Could be an issue with dependency resolution of POM file.
