Question

我在我的gwt.xml模块中使用并放入

guava-18.0.jar
guava-gwt-18.0.jar

编辑：google GWT-Contributors组中有一个讨论她： https ： //groups.google.com/forum/#！topic / google-web-toolkit-contributors/ zYUfanL8zwM

以下是此问题的问题： http ： //code.google.com/p/google-web-toolkit/issues/detail？id = 9036

这个问题有解决方法吗？

编辑：我用Guava 19SNAPSHOT测试并得到了同样的错误。

Answer 1

这是GWT及其使用的JDT版本的已知问题 。

错误报告中给出的修复是升级jdt版本，运行update-jdt.py，并更新dev / build.xml以指向新版本。

或者，您可以尝试不同版本的番石榴，或者开始从番石榴中删除不起作用的方法/类。

或者您可以等到更新版本的gwt发布，这将解决这些问题。
