Question

package my.helloworld;

import org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import org.junit.Test;

public class HomeControllerTest {

}

以上是我的测试代码。即使这个空代码也没有编译。下面是我的pom.xml：

现在，当我运行mvn jetty:run或mvn clean install或mvn test时，我收到以下错误：

之前，没有找到包org的错误。我在这里缺少什么？

Answer 1

您尝试org.springframework.test.web.servlet.result.MockMvcResultMatchers的课程import是spring-test模块的一部分。添加它作为测试依赖项，因为否则，它将不在您的类路径上，因此，您的编译器无法找到它。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>${spring.version}</version>
    <scope>test</scope>
</dependency>

如果你没有导入来自org。*的东西，那么编译器将找不到包org。但是要更准确地说一下，我们需要代码，最好是错误信息。

Answer 2

您是否尝试删除<scope>test</scope>以确定其是否有效？

maven无法从测试用例中找到任何包
