我正在尝试使用最新的JsInterop从javascript调用gwt方法- 下面是我的html的头部部分

在浏览器中，将调用body onload=myFunction（），并始终显示第一个警报

但是单击按钮someValue会显示myFunction的第一个警报，但是预期的host.Employee（）总是显示未定义的警报

Home.html:47 Uncaught ReferenceError: host is not defined

你能告诉我这里出了什么问题吗

我正在为2.8.0-beta1构建gwt maven插件

更新-这是我的pom内容 4.0.0

这通常意味着我需要继承一个模块，我在github上的gwt项目中寻找了一个这样的模块，但到目前为止运气不佳

这是GWT 2.8.0-beta1中使用SDM的

-generateJsInteropExports

时的一个已知问题；已修复但尚未发布：

尝试使用GWT 2.8.0-SNAPSHOT。

将立即试用。此外，没有一个可用的示例实际显示了这样做的简单示例。我不喜欢使用vaadin的东西和封装所有内部的库。我在哪里可以得到快照？我不认为他们在maven Central上严格地说，Central只托管发行版。GWT快照位于Sonatype OSSRH（有时被认为是“中央快照”）上，但位于一个特殊的存储库中：

https://oss.sonatype.org/content/repositories/google-snapshots/

我将上述回购协议添加到我当地的jfrog人工制品厂，我可以通过浏览看到那里的罐子。但由于某些原因，我的eclipse和.m2文件夹没有收到它。对于meI来说有点奇怪，他忘记将artifactory中配置的新repo添加到公开的虚拟repo，即远程repo。。现在jsinterop的工作方式就像一个符咒：）
