java - 如何将类路径添加到maven

问题描述

我想创建一个可执行 jar，其依赖项将位于 lib 文件夹中的存档之外。我发现我可以要求 maven 将依赖项复制到文件夹中并修改我的可执行文件中的清单文件，以知道在哪里寻找所需的类。问题是它没有向我的清单添加任何类路径。绒球：

运行 mvn install 后，我的清单如下所示：

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven 3.8.3
Built-By: abigo
Build-Jdk: 11.0.12
Main-Class: org.sav.app.App

但它不会运行。它告诉我它找不到需要的类。一旦我手动添加类路径，它就可以毫无问题地运行

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven 3.8.3
Built-By: abigo
Build-Jdk: 11.0.12
Main-Class: org.sav.app.App
Class-Path: lib/joda-time-1.6.2.jar lib/joda-time-1.6.2-201110292322.jar

应用：

package org.sav.app;

import org.joda.time.LocalTime;

public class App {

    public static void main(String[] args) {
        LocalTime currentTime = new LocalTime();
        System.out.printf("Current time is: %s%n", currentTime);
    }

}
