    version = '0.0.1-SNAPSHOT'

    dependencies {
        implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-server'
    }

    bootJar {
        mainClassName = 'xyz.jecy.eureka.EurekaApplication'

> Task :eureka:compileTestJava FAILED
/Users/xinzhilimacpro/mytestwork/spring-demo/eureka/src/test/java/xyz/jecy/eureka/EurekaApplicationTests.java:3: 错误: 程序包org.junit.jupiter.api不存在

失败了 但是因为eureka 不需要test，而且也没有引对应test的包 删掉

  1. 继续 gradle clean build
