【问题描述】：
当我尝试在 Eclipse 项目中运行带有 JUnit 测试的 Maven 时，出现以下错误：

按照我的 pom.xml 下面：

我的主要课程：
package com.algaworks.curso;
public class Main {
public static void main(String[] args) {
System.out.println("Hello Maven");
}
}
最后是我的测试课：
package com.algaworks.curso;
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class FibonacciTest {
@Test
public void deve_retornar_fibonacci_posicao_1() {
assertEquals(1L, 1L);
}
}
当我单独运行我的测试类时，它运行完美。如果我尝试在没有测试的情况下运行 Maven 项目（目标：exec:java），它也会运行完美。
错误发生在我尝试使用 JUnit 测试运行 Maven 项目时（目标：干净的项目）。
【问题讨论】：
-
当您尝试从终端运行它时会发生什么？
-
我不知道如何从终端运行它。我在 Eclipse 中使用 Maven 插件，如果我配置为在没有测试的情况下运行（目标：exec:java），它会完美运行。
-
尝试从包含
pom.xml的项目目录运行mvn clean install（安装maven后）
