Maven не находит org.junit, хотя он в зависимостях

Я хотел добавить тест к моему маленькому проекту (обратите внимание, что я удалил некоторые биты из кода и изменил имена пакетов, поэтому, если есть какая-либо ошибка, которую вы видите по этому поводу, возможно, это не так:)):

package my.pckg;


import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;


public class SignedRequestCallbackTest {


    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testCorrectSignedRequest() {
        assertTrue(false);
    }

}

(Я также попытался распространиться из TestCase, чтобы удалить статический импорт, но это не помогло)

После запуска mvn test он показывает мне ошибку, что он не смог найти org.junit:

Версия mvn:

Apache Maven 3.0.3 (r1075438; 2011-02-28 18:31:09+0100)
Maven home: /usr/share/maven
Java version: 1.6.0_41, vendor: Apple Inc.
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: de_CH, platform encoding: MacRoman
OS name: "mac os x", version: "10.8.2", arch: "x86_64", family: "mac"

Обратите внимание, что я не эксперт в java и не на maven, а просто начал работу (особенно с maven). Из того, что я видел из других статей и вопросов, у меня должны быть тесты в src/test/java и мой "реальный" код внутри src/main/java - я сделал это вот так.

Также я удалил всю папку ~/.m2/и все еще не работал.

Я также запускал mvn test -X, но это не помогло мне. Если я должен опубликовать его, скажите мне об этом.
