【问题描述】：

我有一个 GWT 应用程序，它广泛使用代码拆分和国际化，因此会生成许多单独的文件 (1000+)。我想使用 Google Plugin for Eclipse 将我的 GWT 应用程序部署到 App Engine，但是当我尝试时，我在 Eclipse 控制台上收到以下错误：

Deploying:
    Uploading 1187 files.
     on backend null.
java.io.IOException: Error writing to server

有没有人知道什么可能已经南下？

距离我上次成功部署已经快一个月了

【解决方案1】：

UnzipperServlet 可用于在上传所有静态文件之前对其进行压缩。因此，您无需上传数百个静态文件，而是上传一个 zip 文件。

UnzipperServlet 是专门为解决 GAE 的“文件过多”问题而创建的。

编辑： 文件限制似乎已从 1000 个提高到 3000 个。所以你可能会忽略我的“解决方案”。
