使用 ProGuard 混淆 clojure uberjar

我想知道是否有人有使用 proguard 混淆他们的 leiningen 编译的 uberjar 的经验。我已经尽力在谷歌上寻找解决方案，但找不到真正的答案。我想知道这是否可能。

我一直在尝试混淆默认的 lein 项目。这是 core.clj 文件：

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

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

项目文件：

(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)

和我的混淆器配置文件：

-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*(...);
}

每当我尝试运行混淆的 jar 时，都会收到以下错误：

我不太确定我在这里做错了什么...我尝试遵循 clojure 目标 proguard 教程用 proguard 进行混淆 http://www.deepbluelambda.org/programming/clojure/creating-android-applications-with-clojure--slimming-things-down-with-proguard，但是它是 android 和 ant 特定的，所以我想知道使用 lein 的桌面应用程序的过程是否完全不同。

提前致谢。

从上面复制：

混淆 uberjars

1. 准备project.clj文件

这是我的副本（简单，默认的 lein 项目，带注释）：

(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
  )

这里没有更多内容......还要确保（:gen-class)包含在您的名称空间声明中。

构建 uberjarlein uberjar我们将开始下一步。

2. 准备 ProGuard 配置文件

我的文件副本再次附有注释

# 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[]);
}

就是这样。现在使用新的配置文件运行 proguardjava -jar proguard.jar @myconfig.pro。您应该看到一堆输出，因为-printseeds标志（如果您不想看到混淆器将保留哪些类，您当然可以将其删除）。
