Question

我真的很难开始使用Google App Engine，因为Cloud Endpoints教程的设置并不像我预期的那样顺利。

在我创建MyBean.java和YourFirstAPI.java之后出现问题，导航到包含pom.xml的文件夹并运行＆＃34; mvn clean install＆＃34;。发生此错误：

[ERROR] Plugin com.google.appengine:appengine-maven-plugin:1.9.18 or one of its dependencies could not be resolved: Could not find artifact com.google.appengine:appengine-maven-plugin:jar:1.9.18 in central (https://repo.maven.apache.org/maven2) -> [Help 1]

我已经尝试重新安装maven，我尝试过运行＆＃34; mvn clean install -U＆＃34;但它没有帮助。

这是运行mvn -version

的结果

mvn -version

信不信由我不是一个完整的新手并且之前曾在实习中使用过GAE，但是在我自己的电脑上安装它会被证明是一场噩梦。我已经把头发撕成了很久了，所以任何建议都会非常感激。

有趣的是，尽管教程说的内容或Maven通过原型插件生成的内容，目前还没有版本1.9.18的appengine-maven-plugin。尝试在POM中切换到之前的版本1.9.17。还要在依赖项中将版本号从1.9.18更改为1.9.17。

干净安装插件上的GAE / Maven错误“com.google.appengine：appengine-maven-plugin：1.9.18或其某个依赖项无法解析”
