swift 即使导入库并安装所有组件后,Eclipse中的WindowBuilder也无法工作

在我的学习中,我只得到了关于Swing和Java GUI管理的非常简短的指导,所以我决定自己动手,并试图弄清楚如何使用Java构建一个好看的GUI。
在这样做的时候,我遇到了WindowBuilder,并决定将其添加到我已经构建的项目中,目前我通过控制台(一个使用pIRCbot库的Twitch Bot)的用户输入来工作。然而,即使在将WindowBuilder导入到我的项目中,扩展Composite并执行官方教程第一部分中所示的操作后,我仍然收到一个错误消息:
未知的GUI工具包分析程序分析了编译单元,但不能识别任何GUI工具包,因此WindowBuilder不能显示任何GUI来编辑。这可能是由下列原因之一引起的:
该类不是可编辑的UI类,并且不包含UI组件。WindowBuilder无法识别该类中使用的GUI工具包或库。WindowBuilder无法识别受支持的GUI工具包中的GUI类型/模式。类路径存在问题。例如,编译单元使用SWT类,但SWT/JFace库未包含在类路径中。
这是堆栈跟踪:

下面是我试图在WindowBuilder中打开的类的代码:

package twitchChatBot;
import java.io.IOException;
import org.eclipse.swt.widgets.Composite;
import org.jibble.pircbot.*;

public class MyBotMain extends Composite {

    private String channel;

    public MyBotMain(Composite parent, int style) {
        super(parent, style);
        }

    public static void main(String[] args) {
        decideChannel();
        }

    public static void decideChannel() {
        connectToChannel("");
    }

    public static void connectToChannel(String channel) {
        MyBot bot = new MyBot(channel);
        try {
            bot.connect("irc.twitch.tv.", 6667, "oauth:***");
        }
        catch(NickAlreadyInUseException e) {
            System.out.println("Username already in use!");
        }
        catch(IrcException e) {
            System.out.println("General error!");
        }
        catch(IOException e) {
            System.out.println("IO error!");
        }
   }
    @SuppressWarnings("unused")
    private void setChannel(String channel) {this.channel = channel;}
    @SuppressWarnings("unused")
    private String getChannel() {return this.channel;}

    @Override
    protected void checkSubclass() {

    }

}

我尝试了我能找到的大多数修复方法,但似乎没有一个能帮我解决问题。有人知道发生了什么吗?
提前感谢!:)
编辑1:按要求添加源代码:)

您扩展了需要WindowBuilder的SWT功能的SWT组合。可能您只安装了Swing支持功能。
最好的建议是使用帮助菜单从Eclipse Marketplace安装WindowBuilder。然后接受所有建议的选择。不要安装XWT支持。
重新启动后,GUI Toolkit应能被设计人员识别。

很晚才做出回应,但仍在为其他正在搜索这个解决方案的人发帖,正如我所看到的,许多其他人已经在其他平台上搜索了答案,包括这里。
我遇到了这个问题,在“设计”选项卡下它会说“已知的GUI工具包“,在”问题“选项卡下也有几个错误,主要是读“jframe无法解析为一种类型“
我可以通过删除module-info.java来解决这个问题。我忘了我在哪里读到它没有包含在要使用的产品中,但它建议输入其他内容。当这不起作用时,我简单地删除了它,因为我拥有的版本更新得多。
瞬间解决。
