无法使用 Jar 文件找到或加载主类

问题描述：

我正在尝试使用

@echo off
java -jar Test.jar
pause

随着

Manifest-Version: 1.0
Main-Class: classes.TestClass

在Jar目录下，解压后可以清晰的看到classesTestClass文件.

In the Jar directory, I can clearly see a classesTestClass file when I extract it.

classes.TestClass 确实有一个 public static void main(String[] args).

classes.TestClass中的Package Deceleration是package classes;

Package Deceleration in classes.TestClass is package classes;

但我仍然不断收到错误信息

But I still keep getting the error message

Could not find or load main class classes.TestClass

对于这个问题，我已经解决了所有我能找到的问题，但似乎没有任何帮助.

I've been through everything I've been able to find with this problem, and none of it seems to help.

我尝试编辑类路径、重做清单、安装新的 JRE.

I've tried editing the classpath, redoing the manifest, installing the new JRE.

我还应该做什么?

答

我是这样工作的:

TestClass.Java

package classes;

public class TestClass {

    public static void main(String[] args) {
        System.out.println("Test");
    }

}

在命令行上使用 javac 生成 TestClass.class.将 TestClass.class 放在文件夹 classes/ 中.

Use javac on the command line to produce TestClass.class. Put TestClass.class in a folder classes/.

MANIFEST.MF

Manifest-Version: 1.0
Main-Class: classes.TestClass

然后运行

jar cfm test.jar MANIFEST.MF classes/

然后运行它

java -jar test.jar
