org.junit.runner 不存在

Question

我正在尝试使用 JUnit 测试和 Maven 构建 Java Spring 项目。

我的pom.xml 有

        </plugin>
    </plugins>
</build>

我的测试文件在 src>test>Java>com.class.name.test>testclass.class

我不明白为什么会发生此错误，我也尝试删除范围变量。我的项目结构显示 Maven:junit:4.12 所以我不明白为什么它找不到所需的依赖项

当您刚接触 Spring Boot 时，让 Spring Initializr 创建您的 pom.xml。它将创建一个有效的pom.xml。
