问题描述

我正在尝试使用eclipse导出jar功能为eclipse项目生成jar文件.我正在对清单文件中的库进行绝对引用

I am trying to generate jar file for the eclipse project using eclipse export jar feature. I am making absolute reference to a library in my manifest file

Manifest-Version: 1.0
Sealed: true
Main-Class: org.ad.TestMain
Class-Path: D:/demojar/commons-lang3-3.8.1.jar

我也尝试过使用Class-Path: file:///D:/demojar/commons-lang3-3.8.1.jar 和相对路径,例如 lib/commons-lang3-3.8.1.jar

I also tried with Class-Path: file:///D:/demojar/commons-lang3-3.8.1.jar and relative path like lib/commons-lang3-3.8.1.jar

我的项目结构如下所示

My project structure is shown here

我参照清单文件导出罐子,如下所示

I export the jar as shown below making reference to the manifest file

解压缩jar时,在meta-inf文件夹下生成的清单文件不包含类路径引用.代码抱怨库不存在.我该如何解决这个问题?

When I unpack my jar, manifest file generated under meta-inf folder does not contain classpath reference.The code complains about library not existing. How can I resolve this issue?

我的主要问题是为什么在meta-inf下的清单文件中生成的类路径未显示引用的类路径?

My main issue here is why classpath generated in the manifest file under meta-inf does not show the classpath referenced?

推荐答案

从类路径中删除 D:,并相对于主jar所在的路径进行构建

Remove the D: from the classpath and make the path relative to where your main jar is located

即)

folder/
folder/YourJar.jar
folder/lib/commons-lang3-3.8.1.jar

清单应该是

Main-Class: org.ad.TestMain
Class-Path: lib/commons-lang3-3.8.1.jar
