我使用 Spring Initializr 生成了一个 Spring Boot Web 应用程序，使用嵌入式 Tomcat + Thymeleaf 模板引擎，并将其打包为可执行 JAR 文件。
使用的技术：
Spring Boot 1.4.2.RELEASE、Spring 4.3.4.RELEASE、Thymeleaf 2.1.5.RELEASE、Tomcat 嵌入 8.5.6、Maven 3、Java 8。
现在我想使用类实现一个测试SpringApplicationConfiguration，所以我导入了
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
但即使我已经多次更新项目，我也会收到此错误
The import org.springframework.boot.test.SpringApplicationConfiguration cannot be resolved
我还尝试通过右键单击 Eclipse 中的 pom.xml 和 'Maven Add Dependency' 添加依赖项，
做mvn clean dependency:tree 依赖是存在的，但是做mvn clean compile，mvn dependency:purge-local-repository 我得到了package org.springframework.test.annotation does not exist
