gcloud：部署失败，原因是：无法复制证书

Question

使用 windows 10，我正在尝试使用 gcloud maven 插件来部署我的虚拟机管理的 appeengine 项目。所以在成功运行 mvn clean install 后，我运行 mvn gcloud:deploy ,它在控制台上失败并显示以下输出。

我正在使用 gcloud maven 插件版本 2.0.9.90.v20151210 如下

<plugin>
    <groupId>com.google.appengine</groupId>
    <artifactId>gcloud-maven-plugin</artifactId>
    <version>2.0.9.90.v20151210</version>
    <configuration>
        <version>test-gcloud-plugin-v1-1x16</version>
        <runtime>java7</runtime>
        <verbosity>debug</verbosity>
        <log_level>info</log_level>
    </configuration>
</plugin>

使用最新的云 sdk

知道为什么会这样吗？

Answer 1

我遇到了同样的问题，并将其归结为 App Engine 使用 pscp.exe（Putty 安全副本）时出现的问题。该程序提示您对警告消息说“是”，但是当 App Engine 运行它时，它会关闭标准输出，因此您看不到警告。解决方法是在看到Error copying certificates 错误时在控制台中输入y，然后输入enter。

我已经为 Google 开了一张票（有关更多信息，请参阅）：https://code.google.com/p/google-cloud-sdk/issues/detail?id=529

Answer 2

您的证书很可能位于受保护的目录中。我在 Mac 上遇到过这种情况，我不得不使用 sudo（Windows 世界中的runas）来调用 gcloud。
