为了看eureka源码，从github上clone下了eureka项目。eureka在github上面的项目是gradle项目，平时使用的maven比较多，gralde基本上没有接触过，clone下来之后，用idea2018破解版import project之后，导入配置出错，因为gradle在导入这两个plugin时，id 'nebula.netflixoss' version '8.8.1' id 'org.gretty' version '2.1.0'，报not fount error，看了几种网上的解决方法，一个是在build.gradle脚本的buildScript和subProject的repositories里添加阿里云maven仓库地址，try，无效。另一种，clone gralde plugin的gradle-netflixoss-project-plugin工程，将resources和main下文件拷贝到eureka的resources下，再使用gradle重新导入，这一次，没有报not found error了，在Build model 'org.jetbrains.plugins.gradle.model.GradleExtensions' for root project 'eureka' 这步时，提示java.lang.NoClassDefFoundError: org/gradle/api/internal/plugins/DefaultConvention，类找不到。根据github上gradle的issues讲的，是idea版本太低导致，换成高版本就不存在了。于是乎，高高兴兴下载了idea 2021.03community。好了，又报
