GWT Deploying to Google 遇到错误答案

【问题标题】：GWT Deploying to Google has encountered a faultGWT Deploying to Google 遇到错误
【发布时间】：2013-01-05 06:11:07
【问题描述】：

遇到一个我无法修复的错误。看起来像是内存问题，但堆栈跟踪有点像在编译中的无限循环一样循环？

运行 Eclipse Juno 使用 Google App 引擎。

当我尝试将一个应用程序部署到 GAE 但另一个 Google App Engine 应用程序可以运行时，我收到错误。

我看到的错误： GWT 编译失败

从更新站点下载的 site.xml 文件不包含任何 ID 为“com.google.appengine.eclipse.sdkbundle.e42.feature”的元素。无法确定是否有可用更新。

eclipse.buildId=M20120914-1800

【问题讨论】：

标签： eclipse google-app-engine eclipse-plugin

【解决方案1】：

如果它太明显或超出主题，请原谅，但您是否尝试设置或修改编译器指令：jvmarg -Xss？

build.xml 文件中的 <jvmarg value="-Xss16M"/> 之类的内容可能会有所帮助。

【讨论】：

【解决方案2】：

这可能与损坏的缓存有关。删除您的 gwt-UnitCache 文件夹。如果这不起作用，请删除您的 AppData\Local\Temp 文件（如果在 Windows 下），因为那里有许多 gwt 生成的文件。
