grails，应用程序成功运行后出错，我的项目上有红色感叹号？

我是grails新手，在运行grails应用程序时遇到了一个问题。虽然它在我的应用程序中运行良好，但每次运行应用程序时都会看到错误，这让我很紧张。我的项目上还有红色感叹号，是什么

有人能告诉我怎么修吗

在grails命令行上逐个运行上述4个命令1）刷新依赖项2）清除3）编译4）运行应用程序

只需删除view.gsp中的

类型标记，一切正常，

我最近自己解决了这类问题。

我尝试过，但没有成功。我试图在“窗口>显示视图>问题”中查看问题，我发现我的项目和我的工作区之间的版本不一样。我想我的项目图标上的红色感叹号就是这样。但是在运行我的应用程序后，我指定的earlies错误仍然存在。请尝试升级您的项目，对于升级，请通过我尝试升级我的项目，但错误仍然存在。这是错误。Groovy:编译器不匹配项目级别为：1.8工作区级别为2.0项目预期的Groovy编译器级别与工作区编译器级别不匹配。转到项目属性->Groovy编译器设置此项目的Groovy编译器级别转到首选项->Groovy->编译器->切换到1.8.6.xx单击此按钮。我希望你的问题会得到解决。
