我在Vaadin8迁移后需要Widgetset编译错误

问题描述 投票：1回答：2

我刚刚将我的Vaadin项目从7.7.6迁移到8.0.5。首先，我想使用Vaadin8迁移工具，但我的IDE使用了太多的vaadin。* import，所以我只是手动完成。经过几个小时的工作（兼容包导入）maven构建再次工作，我想在我的浏览器中打开WebApp但我得到“无法加载Widgetset ...”错误消息。我认为我必须重新编译Widgetset但是vaadin-maven-plugin会抛出一个错误：

编辑04.05.2017：我删除了QueryDSL依赖“querydsl-apt”并且widgetset正在编译...有谁知道为什么会这样？

</module>

有谁知道什么出错了？

最好的祝福

通常NoSuchMethodError表示类路径问题，从某种意义上说，您在编写代码时在cp中拥有的库（并且您的IDE正在编译内联代码以检查错误）是与maven编译中的库不同的版本 - 时间cp。因此，在编译或运行代码时，不再能找到编写代码时可用的方法（请参阅late binding）。

在您的特定情况下，由于使用JDT版本的QueryDSL依赖项和使用引用另一个JDT版本的GWT插件的Vaadin maven插件，这很可能是间接后果。

作为一种解决方法，您可以从QueryDSL版本或Vaadin maven插件中获取JDT传递依赖关系，并尝试查看是否有效。

附：要查看究竟是谁正在引用JDT依赖项，您可以运行explicitly exclude
