使用Google-App-Engine在Java 8中部署应用程序时,如何修复GWT中的错误

问题描述 投票:0回答:0

由于应用引擎的即将到来的限制,即使用Java 7部署应用程序,我需要切换到Java 8应用程序并进行部署,这会导致与gwt相关的错误。

我试图将gwt插件的版本从2.6.1更改为2.8.2和2.8.0。

我还尝试过根据其他关于gwt错误的帖子添加依赖项,但是它没有任何改变。

最后,我尝试使用以下命令在不编译gwt项目的情况下部署应用程序:clean install -Dgwt.compiler.skip = true package appengine:update应用程序已成功部署但无法正常工作,因此我仍然需要找到解决方案。

这是我的pom.xml文件的一部分

        </configuration>
      </plugin>
      ...
   </plugins>
   ...
</build>

这是我给部署到appengine的命令

-X clean install appengine:update

这是我从部署中得到的错误(我删节了几行,因为对于Stackoverflow而言太长了):

我希望该构建能够成功并且不会出现这些错误,并且希望将正在运行的应用程序部署到Java 8中的应用程序引擎。在此先感谢您的帮助
