我需要将Scala库缩小为仅包含项目所需的文件（stayAway）。
问题是，它只是给我一个带有项目文件的jar;不是缩小的图书馆。在输入/输出菜单中，我尝试了各种可能的组合：
(Configuration used below)
1.
Programs Jars (PJ): Project Jar, Output Jar
Library Jars (LJ): Scala Library Jar, Java Library Jar
Yields: My original project files in a jar
2.
PJs: Project Jar, Scala Library Jar, Output Jar
LJs: Java Library Jar
Yields: My project files coupled with the entire Scala library in a jar
3.
PJs: Scala Library Jar, Output Jar
LJs: Project Files, Java Library Jar
Yields: The entire Scala library in a jar
我只想要一个缩小的Scala库jar！它似乎完全无视我的项目文件。
我正在使用以下配置（由GUI生成）：
-injars 'C:\Users\Brendon\Desktop\stayAway'
-outjars 'C:\Users\Brendon\Desktop\ProGuard Output\shrunkScalaLibrary.jar'
-libraryjars 'C:\Users\Brendon\Desktop\scala-library.jar'

答案 0 :(得分：1)
我最终在7个多小时后才开始工作了。我会发布我在这里做的，部分是为了我将来的参考，部分是为了让其他人免于头痛和浪费的一天。
我使用命令行工具而不是GUI。我不知道为什么会有所作为，但事实确实如此。
我使用以下配置文件（保存为config.pro）：
-injars ".\classes"(!META-INF/MANIFEST.MF)
-injars "C:\Users\Brendon\.ivy2\cache\org.scala-lang\scala-library\jars\scala-library-2.11.5.jar"(!META-INF/MANIFEST.MF)
-libraryjars "C:\Program Files\Java\jre1.8.0_31\lib\rt.jar"
-outjars "C:\Users\Brendon\Desktop\shrunkScalaLibrary.jar"
-dontnote
-dontwarn
-ignorewarnings
-dontobfuscate
-keep public class stayAway.MainFrame {
public static void main(java.lang.String[]);
}
injar更改为类文件的父文件夹（在包文件夹上方），以及scala库jar的位置
outjar只是输出位置-dontobfuscate所以我可以查看生产的jar。它没有必要，似乎让你输出的罐子变大（~4x）我将config.pro和我的类文件夹复制到proguard lib文件夹中（快速而脏）。类文件夹应位于包文件夹上方。就我而言，这看起来像：
- classes
- stayAway
- (All my classes)
使用shift + F10我打开了一个命令提示符到当前位置（proguard/lib）
我运行了命令java -jar proguard.jar @config.pro，输出：
ProGuard, version 5.2

PROFIT！
如果你遇到麻烦，我可能会模糊地记得我做了一段时间。
祝你好运
编辑：
-keep部分会产生错误。我想这定义了你的程序的入口点，所以它知道要保留什么。就像我说的那样，我正在制作一个没有main的applet;所以我不确切地知道这里发生了什么。
