我正在为 Google Glass 开发 Glassware。我想看看我是否可以将 Glassware 上传到 App Engine，所以我得到了支持 App Engine 的最新版本（位于 GitHub 上：https ://github.com/googleglass/mirror-quickstart-java/releases/tag/app -引擎）。我更改了 API 代码和我的 App Engine 应用程序名称，并使用 Eclipse 上的 Google App Engine SDK 和 appcfg.cmd 通过命令提示符将其部署到 App Engine。部署它时，我收到以下错误：

Failed to compile the generated JSP java files to App Engine

我得到的完整错误如下（这是来自它的命令提示符版本）：

Index.jsp 位于此处：https ://github.com/googleglass/mirror-quickstart-java/blob/8a7edd5eb8c2710b841294ca5d7d69bd176693bf/web/index.jsp

由于某种原因，mirror.model jar 旁边有一个奇怪的源图标。其他罐子都没有。它的图片如下：在此处输入图像描述我可能会从另一个地方得到这个罐子吗？

另外，有人建议添加

<packaging>war</packaging>

到 pom.xml。这也没有解决问题，它与我之前遇到的错误相同。

我不知道为什么会收到此错误。JSP 文件似乎有问题，但这是 Glass 团队发布的版本。也许我需要改变其中的一些东西？也许是某些罐子有问题？谢谢您的帮助。

我有同样的问题，我通过添加解决了它

<packaging>war</packaging>

在 pom.xml 中，所以 pom.xml 文件是：

` 

<modelVersion>4.0.0</modelVersion>
<groupId>com.google</groupId>
<artifactId>glass-java-starter</artifactId>
<version>0.1-SNAPSHOT</version>
<packaging>war</packaging>
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

` 现在我正在使用以下命令编译并上传到应用引擎

mvn clean install
appcfg.sh update target/glass-java-starter-0.1-SNAPSHOT

如果您仍然有问题，请告诉我。
