我想将我的 GWT 2.3 应用程序打包到一个 war 文件中，并将其部署在 weblogic 服务器上。我用 ANT http://www.rubiconred.com/blog/build-package-a-gwt-app-to-war-using-ant/找到了这个解决方案。但有一个问题。编译目标抛出一个错误，在我看来 ANT 使用了错误的 Java 版本。但是当我运行时 -> Ant Build... -> JRE 版本是正确的（1.6.0_11）。所以这个问题的解决方案不起作用。而且我还不确定java版本是否是问题所在。

控制台输出如下所示：

所以我的问题是：

来自ant的Java版本是问题吗？

或者：

有没有更简单的方法将 GWT 应用程序打包到 war 文件，然后是 ant 脚本？我尝试了一些东西，但下确实有效。

来自ant的Java版本是问题吗？

不
。看起来您缺少类路径中的依赖项（特别是 Bean Validation API、ICU4j、Apache Commons Lang 和 Servlet API）。

有没有更简单的方法将 GWT 应用程序打包到 war 文件，然后是 ant 脚本？我尝试了一些东西，但下确实有效。

这取决于您如何构建项目。如果你已经在使用 Ant，那么使用 Ant 来打包你的 WAR；如果您使用的是 Maven，请使用 Maven；如果您使用的是 Make，则使用 Make；如果您使用的是 shell 脚本，请继续使用它；等等。
如果您没有构建脚本并且仅依赖于您的 IDE，那么您将遇到比打包 WAR 更严重的问题。但是，您仍然可以在 Eclipse 中做到这一点（我知道可以做到，但我不知道如何做到）。
