Question

我一直在关注如何从Eclipse EE部署到Appspot的Udacity教程。

https://classroom.udacity.com/courses/ud859/lessons/1215898636/concepts/14551185740923#

这里是写出来的指示......

https://docs.google.com/document/d/1EO3pQ53DQP3SW4LCnOLiUtgAKCWbqXVprBWj0TOlRUM/pub

我相信我已经跟着它了，但当我尝试更新应用程序时，它坚持认为该项目不存在并且给我404错误。但是，如果我去Google Cloud Platform，项目就在那里，我可以看到项目ID。

我有，

将appengine-web.xml中的应用程序更改为项目ID hello-around-the-world-155900
根据提示授予App Engine appcfg权限
安装了Google eclipse插件并使用与项目所有者相同的帐户登录Google
我使用的是jdk 1.7.0_80和maven 3.3.9
创建了一个新的App引擎项目并重新启动了我的计算机

这是我的appengine-web.xml

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>hello-around-the-world-155900</application>
    <version>1</version>
    <threadsafe>true</threadsafe>
    <system-properties>
       <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>
</appengine-web-app>

这是控制台日志，

有人可以就我错过的内容提出建议吗？这里似乎没有很多变量，很多人都使用这个服务所以必须在某个地方有答案。

Answer 1

错误消息显示：

This application does not exist (project_id=u'845830179642'). To create an App Engine application in this project, run "gcloud beta app create" in your console.

此处的问题是您需要在GCP项目中创建App Engine application才能部署。您可以在命令行中使用gcloud app create命令执行此操作（不再需要beta），或者您可以转到Cloud Console中的App Engine仪表板并创建它。

请参阅有关如何创建GCP项目和App Engine应用程序的文档：

无法将HelloWorld App部署到Appspot
