eclipse - GWT Deploying to Google 遇到错误

Question

出现我无法修复的错误。看起来像一个内存问题，但堆栈跟踪是一种循环，就好像编译中的无限循环一样？

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 时出现错误，但另一个 Google App Engine 应用程序可以工作。

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。

它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。

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 ？

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