从命令行部署 App Engine 标准项目时出错
我们有一个 App Engine 标准 Java8 项目，其中 JSP 文件用于视图，并且每个 jsp 文件都将使用 util 类，因此我们使用 jsp 提供的 page 指令来导入所需的 util 类。代码如下所示
<%@page import="util.AssetUtils"%>。
我们在任何 JSP 中都没有出现任何错误，甚至在使用 Google Cloud Tools for Eclipse 插件完成部署时都没有问题。
但是当我们尝试使用命令行部署时。对于某些 jsp 文件，我们收到以下错误。

有人可以帮忙吗？
谢谢！
We have a App Engine standard Java8 project, where JSP files were used for views and each of those jsp file will be using a util class, so we've used the page directive provided by jsp to import the required util class. The code looks like below
<%@page import="util.AssetUtils"%>.
We don't have any error in any of those JSPs' and even the deployment was fine when done with Google Cloud Tools for Eclipse plugin.
But when we tried deployment with command line. We are getting the below error for some of the jsp files.

我认为在 Google Cloud Tools for Eclipse 插件中运行此程序时不会出现错误，因为它会为您下载所需的依赖项。要使用 javac 命令在 CLI 中运行它，您需要指定 CLASSPATH。位于 /home/user 目录内部非常重要。
OP 确认他遵循了上述建议，并将类路径中的输出路径位置更改为指向 WebContent 文件夹内的目录。现在类文件在部署期间可用并且工作正常。
I think there is no error while running this in Google Cloud Tools for Eclipse plugin because it downloads required dependencies for you. To run it in CLI using the javac command, you need to specify CLASSPATH. It is important to be inside of the /home/user directory.
OP confirmed that he followed the above suggestion and changed the output path location in the classpath to point a dir inside his WebContent folder. So now the class files are available during the deployment and it is working fine.
