Proguard可以忽略库中未使用的类吗? [英] Can proguard leave out the unused classes of the libraries?

问题描述

我有一个使用pdfbox库的Java应用程序，其大小为10mb.我只使用了该库的几个类.

I have a java application using the pdfbox library, which makes 10mb. I use just a few classes of this library.

我认为ProGuard会为我的应用程序生成一个独立的jar.但是ProGuard生成的jar仍需要/lib文件夹中的pdfbox.jar才能运行.难道我做错了什么?我如何实现我的目标? (省去了我不使用的99％的库类).

I thought that ProGuard would generate a standalone jar for my application. But the jar generated by ProGuard still needs the pdfbox.jar in the /lib folder to run. Am I doing something wrong? How could I achieve my goal? (leaving out the 99% of the library classes I don't use).

评论后请注意: -原始的jar及其库是使用Netbeans生成的.我最初使用ProGuard GUI，但是在收到有关此问题的评论后，我转向了脚本编写.结果相同:仅当库位于jar旁边的/lib文件夹中时，该应用程序才能工作.

Note after comments: - the original jar and its libraries are generated with Netbeans. I first used ProGuard GUI but following the comments I received on this question, I switched to scripting. Same result: the app works only when the libraries are in a /lib folder next to the jar.

Proguard脚本:

The Proguard script:

推荐答案

尽管对您来说太迟了，但以下工具正是您想要的:

Though it's too late for you, here is the tool doing exactly you wanted:

该工具 minimize-jar 会删除未使用的类并根据verbose:class信息创建一个uber jar.它只有5KB，没有依赖性.

The tool minimize-jar removes unused classes and creates a uber jar based on verbose:class information. It's only 5KB and has no dependency.
