Question

我正在运行三个应用引擎服务，这是我从一项服务中获得的appening-web.xml

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <!-- <application>sandbox-10fb8</application> -->
  <application>XXX-184914</application> 
  <version>1</version>
  <threadsafe>true</threadsafe>
   <runtime>java8</runtime>
  <use-google-connector-j>true</use-google-connector-j>
  <service>XXX</service>

</appengine-web-app>

这就是我在云应用引擎控制台中看到的内容

automatic_scaling:
  min_idle_instances: automatic
  max_idle_instances: automatic
  min_pending_latency: automatic
  max_pending_latency: automatic

当我使用mvn appengin:update时，效果很好。所以我想添加缩放配置。这就是我所做的

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <!-- <application>sandbox-10fb8</application> -->
  <application>XXX-184914</application> 
  <version>1</version>
  <threadsafe>true</threadsafe>
  <automatic-scaling>
    <target-cpu-utilization>0.95</target-cpu-utilization>
    <min-idle-instances>1</min-idle-instances>
    <min-instances>1</min-instances>
    <max-instances>2</max-instances>
    <max-concurrent-requests>50</max-concurrent-requests>
  </automatic-scaling>
   <runtime>java8</runtime>
  <use-google-connector-j>true</use-google-connector-j>
  <service>XXX</service>
</appengine-web-app>

现在，当我执行相同的mvn命令时，出现以下错误

如果我清楚地理解了错误消息，则说明我如何键入这些标签，这是找不到的，但我是从Google doc复制而来的。我真的在这里做错了什么？

mvn appengin:update命令似乎正在使用GAE Java SDK中的appcfg命令（请注意错误消息中提到的appcfg日志文件名中的appcfg5084302388655645727.log （您知道），但该功能（目前）还不支持某些最近添加的缩放配置参数，包括target-cpu-utilization。在您提到的文档中：

重要：如果您使用App Engine SDK for Java中的 appcfg 命令进行部署，则无法在您的 appengine-web.xml 。而是按照Setting Autoscaling Parameters in the API Explorer中所述设置参数，或使用 App Engine Admin API。

发现无效内容，以元素“ target-cpu-utilization”开头
