深入查看代码，我可以看到：
[ERROR] Resource org/jboss/errai/ui/demo/client/local/PasswordRequiredPage.html not found. Is the name specified as Class.getResource() would expect?
但是html页面在那里有相应的PasswordRequiredPage.java：
PasswordRequiredPage.java：
@Dependent
@Templated("#passwordrequired")
@Page
public class PasswordRequiredPage extends Composite {
}
PasswordRequiredPage.html：
<div data-field="passwordrequired">
<!-- Content -->
</div>
我的应用程序可能出了什么问题？我已经搞定了：
- mvn clean (SUCCESS)
- mvn gwt:compile (FAIL)
- mvn gwt:run (FAILE)
最佳答案
尽管PasswordRequiredPage.html与PasswordRequiredPage.java放在同一文件夹中，但是当gwt-compiler运行时，它应该位于类路径中。
您可以通过两种方式修复它：
将PasswordRequiredPage.html复制到Java编译器生成PasswordRequiredPage.class的文件夹中，完成配置maven-resources-plugin的操作（目标复制资源）
将.html所在的源文件夹添加到编译类路径中。
我从没用过Errai，也不知道它如何使用gwt编译器，但是由于某种原因，它正在向类路径中添加.java文件（也可能是.css和.png），但没有.html文件。
