maven - java maven spring真的可以与google app engine一起使用吗

Question

我使用 maven 创建了一个项目 testprojectapp

mvn archetype:generate -Dappengine-version=1.9.18 -Dapplication-id=testprojectapp -Dfilter=com.google.appengine.archetypes:

我的 pom.xml 在下面

然后我尝试使用 mvn appengine:update 上传

我有另一个基于 spring 的项目在本地运行良好，但在尝试上传项目时出现相同的错误。我看到类似的线程没有任何答案。谷歌或专家请确认这种项目（JAVA + MAVEN3.25 + SPRING 4 + Spring Security）在谷歌应用程序上是否真的可行，或者我是否应该找到另一个云平台。据我所知，这只是谷歌的一个伎俩，让我们创建试用账户。如果我在这里做错了什么，请帮忙。

下面是我的 appengine-web.xml

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>projectid</application>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>

</appengine-web-app>

------------------更新------------- 好的 maven 和 google app 专家，这是给你们的。我从这个网站http://java-in-cloud.blogspot.com/2013/11/java-maven-gae-spring-and-vaadin-all.html中包含了 pom.xml 并且我能够成功构建谷歌给了我代码和所有。下面是我的新 pom.xml。如果有人能指出我遗漏了什么或做错了什么，那就太好了。从来没有在maven上工作过。与此同时，我会发现这是否适用于我拥有的应用程序并更新稍后发生的情况。

好的，所以我能够上传我的 testapp 测试它并且它可以工作。猜猜我将不得不通过maven，这样就不会再发生这种情况了。

任何指点都会有帮助谢谢
