导出的 GUI 项目不会 open/run，使用 eclipse oxygen 导出 Java

Question

我在从 Eclipse Oxygen 导出 GUI 项目时遇到了问题。起初我尝试通过导出>Runnable Jar File>Main Class 来导出我的项目，但是当我尝试打开我的程序时没有任何显示。然后我尝试通过在其中指定一个 Main 方法在它自己的 class 中打开 GUI，并且我不断收到我在标题中输入的错误。任何帮助，将不胜感激。我会 post 我的两个 class 都在这里。

我还使用 WindowBuilder 插件来构建我的 GUI。

主要class

package me.iran.cryptotracker;

import java.util.ArrayList;
import lombok.Getter;
import me.iran.cryptotracker.window.Window;

public class CryptoTracker {

private static SaveFile saveFile = new SaveFile();
private static ReadFile readFile = new ReadFile();


@Getter
public static ArrayList<Crypto> allCrypto = new ArrayList<Crypto>();

public static void main(String[] args) {

    readFile.openFile();
    readFile.readFile();
    readFile.closeFile();

    saveFile.openFile();
    saveFile.updateFile();
    saveFile.closeFile();


    Window.open();

}
}

Answer 1

事实证明，winrar 不喜欢可运行的 jar 文件。我曾尝试右键单击该文件并将其运行作为 java 应用程序 SE 二进制文件，但它不起作用。所以在@Adam Horvath 提到它对他有用之后，我将导出的 jar 设置为默认 java jar 并且它打开得很好。

导出的 GUI 项目不会 open/run，使用 eclipse oxygen 导出 Java

Exported GUI project won't open/run, exported using eclipse oxygen Java

java
