"Plugin not found for prefix app engine" when using maven
提问by Tyler
I am trying to run the command
我正在尝试运行命令
mvn appengine:devserver
but it throws the following error
但它会引发以下错误
[ERROR] No plugin found for prefix 'appengine' in the current project and in the plugin groups
[org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local
(/Users/tylerrice/.m2/repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]
I have never used maven before all this code is from a development company we hired to write the majority of the backend so I am completely lost here. I visited the help page for this error here. I went through the list there and I can't find a pom.xml file either
在所有这些代码来自我们聘请来编写大部分后端的开发公司之前，我从未使用过 maven，所以我完全迷失在这里。我在这里访问了此错误的帮助页面。我浏览了那里的列表，但也找不到 pom.xml 文件

So I had this same error. When I tried to run mvn appengine:devserver for appengine I was getting this same error
所以我有同样的错误。当我尝试为 appengine 运行 mvn appengine:devserver 时，我遇到了同样的错误
[ERROR] No plugin found for prefix 'appengine' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/Users/
I realized that I was up one directory too far, so when I was typing ls and hitting enter I could see my application. I simply needed to type cd [name of application] to go down one directory level to the application itself and it ran fine.
我意识到我上一个目录太远了，所以当我输入 ls 并按 Enter 时，我可以看到我的应用程序。我只需要键入 cd [应用程序名称] 以向下一级目录到应用程序本身，并且它运行良好。

In your POM file the appengine VERSION needs to be explicitly specified. (Not sure why).
在您的 POM 文件中，需要明确指定 appengine VERSION。（不知道为什么）。
" com.google.appengine appengine-maven-plugin 1.9.15 "
“ com.google.appengine appengine-maven-plugin 1.9.15 ”

I had the same problem, nothing helped me, I worked around it by running the app server from the appengine home with the location to my app:
我遇到了同样的问题，没有任何帮助，我通过从 appengine 主页运行应用程序服务器来解决它，并将位置信息发送到我的应用程序：
