Java 在Eclipse中运行带有JUnit项目的Maven时出错

当我试图在eclipse项目中运行带有JUnit的Maven测试时，我遇到以下错误：

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);
    }

}

当我单独运行测试类时，它运行得非常完美。如果我尝试在没有测试的情况下运行一个Maven项目（目标：exec:java），它也会运行得很好

---

当我尝试运行带有JUnit测试的Maven项目时（目标：clean project），错误就发生了。

从您发布的日志来看，问题似乎不在于JUnit测试用例，但是您的maven无法下载一些工件。在repo中，我可以看到maven surefire booter jar的所需版本。我猜网络防火墙或连接存在一些问题…我们可以尝试重新连接到网络，然后运行目标吗？

错误表示surefire插件直接或间接使用的依赖项无法解决。我从未遇到过这个错误，但是，请从以下位置删除您的maven surefire插件文件夹：“.m2\repository\org\apache\maven\plugins” 并重新运行构建，该构建将自动重新下载所有插件文件。

---

在删除之前，请确保备份文件夹，以便分析丢失的内容。

尝试从终端运行文件夹时会发生什么情况？我不知道如何从终端运行文件夹。我正在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），它会运行得很好。尝试从项目目录运行

mvn clean install

，其中包括

pom.xml

（安装Maven后）

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);
    }

}
