我正在尝试部署＆＃34; Hello，World！＆＃34;适用于托管虚拟机Java 8的App on Engine上的Java，并且在运行mvn gcloud：deploy时面临下面列出的错误。在我的本地机器上运行它时没有遇到任何问题（mvn jetty：run）。有人可以指出我做错了什么吗？

如前所述，安装Python并将其添加到路径并没有帮助。我遵循了两件事来使其发挥作用：

关注the link to add .PY extension to PATHEXT variable and edited PATH to add gcould - C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\lib\gcloud

还编辑了PATH以包含与google SDK捆绑在一起的Python路径 - C：\ Program Files（x86）\ Google \ Cloud SDK \ google-cloud-sdk \ platform \ bundledpython;

然后我遇到了谷歌SDK位置的问题，这是通过将配置添加到我的POM.xml来解决的：

<plugins>
      <plugin>
        <groupId>com.google.appengine</groupId>
        <artifactId>gcloud-maven-plugin</artifactId>
        <version>2.0.9.95.v20160203</version>
        <configuration>
            <gcloud_directory>C:/Program Files (x86)/Google/Cloud SDK/google-cloud-sdk</gcloud_directory>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.6</version>
        <configuration>
          <failOnMissingWebXml>false</failOnMissingWebXml>
        </configuration>
      </plugin>

您是否已在搜索路径中安装了Python？

Caused by: java.io.IOException: Cannot run program "python.exe" (in directory "C:\Users\krajendran\AppData\Local\Google\Cloud SDK\java-docs-samples\managed_vms\helloworld\target\appengine-staging"): CreateProcess error=2, The system cannot find the file specified
    ...

建议不要。
