问题描述

我在使用2.6.0版编译gwt应用时遇到错误，最初，我使用具有gwt版本2.6.1的maven进行了编译，然后尝试通过具有版本2.6.0的eclipse进行编译.与版本兼容性有关吗?

I'm getting below error while compiling gwt app with ver 2.6.0, Initially I have compiled it with maven having gwt ver 2.6.1 and then tried to compile it through eclipse having version 2.6.0. Is it related to version compatibility??

推荐答案

发现自己，如果要升级到新版本，我们需要清除gwt-Unitcache

Found out myself, we need to clear gwt-Unitcache if you are upgrading to new version
