用ProGuard混淆clojure uberjars

Question

我想知道是否有人用proguard混淆他們的leiningen編譯uberjars的經驗。我已盡全力在Google上尋找解決方案，但無法真正找到答案。我想知道這是否可能。

我一直在試圖混淆默認lein項目。這裏的core.clj文件：

(ns proguard.core 
(:gen-class)) 

(defn -main 
    "I don't do a whole lot." 
    [& args] 
    (println "Hello, World!")) 

項目文件：

(defproject proguard "0.1.0-SNAPSHOT" 
    :description "FIXME: write description" 
    :url "http://example.com/FIXME" 
    :license {:name "Eclipse Public License" 
      :url "http://www.eclipse.org/legal/epl-v10.html"} 
    :dependencies [[org.clojure/clojure "1.4.0"]] 
    :aot :all 
    :main proguard.core) 

和我的ProGuard配置文件：

-injars clojure/proguard/target/proguard-0.1.0-SNAPSHOT-standalone.jar 
-outjars clojure/test-project 

-libraryjars /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/rt.jar 

-dontshrink 
-dontoptimize 
-dontusemixedcaseclassnames 
-dontpreverify 
-dontnote 
-printseeds 

-keepclasseswithmembers public class * { 
    public static void main(java.lang.String[]); 
} 

-keep class clojure.core__init { public static void load(); } 
-keep class clojure.core_proxy__init { public static void load(); } 
-keep class clojure.core_print__init { public static void load(); } 
-keep class clojure.genclass__init { public static void load(); } 
-keep class clojure.core_deftype__init { public static void load(); } 
-keep class clojure.core.protocols__init { public static void load(); } 
-keep class clojure.gvec__init { public static void load(); } 
-keep class clojure.java.io__init { public static void load(); } 
-keep class clojure.lang__init { public static void load(); } 

-keep class proguard.core__init { 
    public static void load(); 
} 
-keep class proguard.core { 
    public *** super*(...); 
} 

每當我嘗試運行混淆的JAR，我得到以下錯誤：

我真的不確定我在做什麼錯在這裏...我試着遵循一個clojure有針對性的proguard教程obfuscating with proguard，但它是android和ant的特定，所以我想知道如果這個過程是完全不同的桌面使用lein的應用程序。

在此先感謝。

從上面複製：

進行模糊uberjars

1.準備您的project.clj文件

這裏是我的一個副本（簡單，默認雷音項目，評論）：

(defproject proguard "0.1.0-SNAPSHOT" 
    :description "FIXME: write description" 
    :url "http://example.com/FIXME" 
    :license {:name "Eclipse Public License" 
      :url "http://www.eclipse.org/legal/epl-v10.html"} 
    :dependencies [[org.clojure/clojure "1.4.0"]] 
    :main proguard.core 
    ;;; Make sure everything is aot compiled 
    :aot :all 
    ;;; Remove source .clj files from the resulting jar 
    :omit-source true 
) 

這裏沒有太多的東西了...... Al所以請確保（:gen-class)包含在您的名稱空間聲明中。

用lein uberjar構建uberjar，我們即將進入下一步。

2.準備你的ProGuard配置文件

再次我的文件的副本與註解

# Our uberjar 
-injars clojure/proguard/target/proguard-0.1.0-SNAPSHOT-standalone.jar 
# Our output direcotry 
-outjars clojure/obfuscated 

# Link to rt.jar. I'm on a Mac so your path may differ 
-libraryjars /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/rt.jar 

# ProGuard options. Detailed explanation here http://proguard.sourceforge.net/index.html#manual/usage.html 
-dontskipnonpubliclibraryclassmembers 
-dontnote 
-printseeds 

# What we will be doing is obfuscating, shrinking and optimizing the jar. 
# If you experience any problems start out with obfuscation and add the 
# -dontoptimize and the -dontshrink flags and see if it works. 

# Tell proguard to leave the clojure runtime alone 
# You would need to add any other classes that you wish to preserve here. 
-keep class clojure.** { *; } 

# Keep our core__init class 
-keep class proguard.core__init { 
    public static void load(); 
} 

# Keep classes that contain a main method (otherwise we won't be able to run the jar) 
-keepclasseswithmembers public class * { 
    public static void main(java.lang.String[]); 
} 

那它遵循。現在用你的新配置文件java -jar proguard.jar @myconfig.pro運行proguard。由於-printseeds標誌（你當然可以刪除，如果你不想看看proguard保存哪些類），你應該會看到一堆輸出。
