我正在尝试部署“Hello, World！” 用于托管 VM 的应用引擎 Java 8 上的 Java 并在运行 mvn gcloud:deploy 时遇到下面列出的错误。在我的本地机器（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 并将其添加到路径并没有帮助。我遵循了两件事使它起作用：

按照链接将 .PY 扩展名添加到 PATHEXT 变量并编辑 PATH 以添加 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，通过将配置添加到我的 POM.xml 中解决了这个问题：

<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 并在您的搜索路径中？

建议不要。
