我正在尝试在托管虚拟机Java 8的应用程序引擎上为Java部署"Hello，World！"，并在运行mvn gcloud：deploy时遇到以下列出的错误。在本地机器（mvn jetty：run）上运行它时，我没有遇到任何问题。有人可以指出我做错了什么吗？

如前所述，安装Python并将其添加到路径中没有帮助。我遵循了两件事来使其工作：
已点击链接添加 。PY 扩展到 PATHEXT 变量并编辑 PATH 以添加 gcan - 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，这个问题通过向我的POM添加配置来解决.xml：
<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>
您是否安装了 Python 并在搜索路径中？

建议不。
