更新GAE应用程序时出错-缺少appengine-web.xml

Question

早上好，

我正在创建带有某些端点的GAE应用程序。 我上传了我的应用程序很多次，一切正常，但是发生了一些事情（我认为是我的pom.xml），现在我可以打电话了

 maven install

没有错误，但是当我打电话时

maven appengine:update 

控制台显示FileNotFoundException，因为缺少appengine-web.xml。

这是我的堆栈跟踪：

我已经从此处复制了pom.xml中的“ build”部分： https : //github.com/GoogleCloudPlatform/appengine-endpoints-helloendpoints-java-maven/blob/master/pom.xml

当然，我不感到惊讶，因为在我的“目标”目录中只有“类”目录，但是我不知道为什么在此目录中未生成“ WEB-INF”。

- 编辑 -

当然，我已经在WEB-INF目录中创建了appengine-web.xml

这都是我的错。 我有

<packaging>jar</packaging>

代替

<packaging>war</packaging>

在我的pom.xml中，因此无法正确生成项目。
