SpringBoot整合Junit:Exception in thread “main“ java.lang.NoClassDefFoundError解决办法

导入junit-platform-launcher依赖即可

<!--        junit-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>

        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-launcher</artifactId>
            <version>1.8.2</version>
            <scope>test</scope>
        </dependency>

折磨了我一周多的报错，也不知道为啥会报这个错误
