无法将生成的JSP java文件编译为App Engine Google Glass

Question

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-engine）。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将其部署到App Engine。 appcfg.cmd通过命令提示符。部署它时，我遇到以下错误：

Failed to compile the generated JSP java files to App Engine

我收到的完整错误如下（这是来自命令提示符版本）：

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：我可能从另一个地方拿到罐子吗？

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。

我不知道为什么我会收到此错误。这似乎是JSP文件的一个问题，但这是Glass团队发布的版本。也许我需要改变一些东西？也许这是一些罐子的问题？谢谢你的帮助。

Answer 1

我有同样的问题，我通过添加

解决了这个问题

<packaging>war</packaging>

pom.xml中的

，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>

` 现在我使用下面的命令编译并上传到app引擎

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

如果您仍有问题，请告诉我。
