為了看eureka源碼，從github上clone下了eureka項目。eureka在github上面的項目是gradle項目，平時使用的maven比較多，gralde基本上沒有接觸過，clone下來之后，用idea2018破解版import project之后，導入配置出錯，因為gradle在導入這兩個plugin時，id 'nebula.netflixoss' version '8.8.1' id 'org.gretty' version '2.1.0'，報not fount error，看了幾種網上的解決方法，一個是在build.gradle腳本的buildScript和subProject的repositories里添加阿里雲maven倉庫地址，try，無效。另一種，clone gralde plugin的gradle-netflixoss-project-plugin工程，將resources和main下文件拷貝到eureka的resources下，再使用gradle重新導入，這一次，沒有報not found error了，在Build model 'org.jetbrains.plugins.gradle.model.GradleExtensions' for root project 'eureka' 這步時，提示java.lang.NoClassDefFoundError: org/gradle/api/internal/plugins/DefaultConvention，類找不到。根據github上gradle的issues講的，是idea版本太低導致，換成高版本就不存在了。於是乎，高高興興下載了idea 2021.03community。好了，又報

最后，fork eureka項目，將jcenter地址注釋掉，換成阿里雲maven地址，重新導入，over！
