idea环境下如何打包可运行jar？

工作中有时候偶尔写一些工具类、小程序，可是java程序员制作一个可运行jar实在折腾，利用idea开发环境，可以快速打包自己的可运行jar。具体怎么操作呢？

创建一个空白的java项目并完成自己的程序开发

完成java代码：

/**
 * 测试窗口
 * @author binbin
 * @date 2023/9/27 10:29
 */
public class InfoFrame extends JFrame {
    public InfoFrame() {
        setTitle("System Information");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 200);

        //居中显示
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        setLocation((screenSize.width - getWidth())/2, (screenSize.height - getHeight())/2);

        //初始化菜单
        JMenuBar bar = new JMenuBar();
        JMenu menu = new JMenu("帮助");
        JMenuItem exitItem = new JMenuItem("退出");
        exitItem.addActionListener(e -> {
            System.exit(0);
        });
        menu.add(exitItem);
        bar.add(menu);
        setJMenuBar(bar);

        //初始化系统信息
        JTextArea infoTextArea = new JTextArea(6, 10);
        infoTextArea.setText(getSystemInfo());
        infoTextArea.setEditable(false);
        add(new JScrollPane(infoTextArea));
    }

    private String getSystemInfo() {
        StringBuffer b = new StringBuffer();
        b.append("系统系统：").append(System.getProperty("os.name")).append("\r\n");
        b.append("系统版本：").append(System.getProperty("os.version")).append("\r\n");
        b.append("系统架构：").append(System.getProperty("os.arch")).append("\r\n");
        b.append("用户名称：").append(System.getProperty("user.name")).append("\r\n");
        b.append("用户主目录：").append(System.getProperty("user.home")).append("\r\n");
        b.append("当前工作目录：").append(System.getProperty("user.dir")).append("\r\n");
        return b.toString();
    }
}

public class App
{
    public static void main( String[] args )
    {
        EventQueue.invokeLater(() -> {
            new InfoFrame().setVisible(true);
        });
    }
}

代码结构如下：

引入maven-assembly-plugin插件打包

执行maven package

执行maven package命令，target目录将生成一个以jar-with-dependencies结尾的可直接执行jar。
运行命令：

> java -jar info-1.0-SNAPSHOT-jar-with-dependencies.jar

文档包和源码包

<plugin>
    <groupId>org.apache.maven.pluginsgroupId>
    <artifactId>maven-javadoc-pluginartifactId>
    <executions>
        <execution>
            <id>attach-javadocsid>

下次再有测试、运营或者其他部门的同事找你做工具，知道怎样快速制作可执行jar了吧？
