eclipse IDE中的java程序编译错误

Question

我有以下代码,其中eclipse给出以下编译错误:

Multiple markers at this line
- The hierarchy of the type TutorialsApplication is inconsistent
- The type com.vaadin.terminal.Terminal$ErrorListener cannot be resolved. It is indirectly referenced 
 from required .class files
- The type com.vaadin.terminal.URIHandler cannot be resolved. It is indirectly referenced from 
 required .class files

我的代码是:

package com.example.tutorials;

import com.example.component.Window.HomeWindow;
import com.vaadin.Application;

@SuppressWarnings("serial")
public class TutorialsApplication extends Application {
    // @Override
    public void init() {
        HomeWindow main = new HomeWindow("Welcome to FunFusion Content Management System");
        setMainWindow(main);
        main.initWindow();
    }
}

Answer 1

这意味着vaadin库,无论它是什么,都依赖于某些第三方JAR文件或文件,当您编译和运行应用程序时,这些文件或文件必须存在于您的CLASSPATH中,但是您缺少这些文件或文件.
