我正在使用proguard缩小阴影jar以用作命令行工具。阴影jar工作正常，但我在运行proguard创建的jar时遇到异常。该应用程序使用Guice注入，我添加了我在SO上找到的配置，主要是this answer。
这是例外：

这就是产生它的配置：
-injars acme-cli-0.2.1-SNAPSHOT.jar
-outjars target/acme-cli-0.2.1-SNAPSHOT.jar
-libraryjars /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/jre/lib/jce.jar
-libraryjars /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/jre/lib/jsse.jar
-libraryjars /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/jre/lib/rt.jar
-dontobfuscate
-dontpreverify
-dontoptimize
-printmapping mapping.map
-ignorewarnings
-keepattributes *Annotation*,Signature
# Keep - Applications. Keep all application classes, along with their 'main' methods.
-keep public class com.acme.ui.cli.Main {
public static void main(java.lang.String[]);
}
# Keep Guice-related classes
-keep public class javax.inject.**
-keep class com.google.inject**
-keep class * extends com.google.inject.AbstractModule
# keeps all fields and Constructors annotated with @Inject and @AssistedInject
-keepclasseswithmembers class * {
@com.google.inject.Inject <fields>;
@com.google.inject.Inject <init>(...);
}
-keepclasseswithmembers class * {
@com.google.inject.assistedinject.AssistedInject <fields>;
@com.google.inject.assistedinject.AssistedInject <init>(...);
}
当我添加此问题时，问题就消失了：
-keep class * {
<init>(...);
}
但它保留了更多的类，并且增加了jar的大小。我正在使用proguard 4.10并尝试过4.9。这些是我试验过的一些看似最相关的选项：
-keepattributes *
-keepparameternames
-keep class sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl {
<init>(...);
}
由于它似乎与Guice有关并且让所有构造函数都能解决问题，我还尝试了各种方法来配置保留选项而没有结果。但我必须说我完全不了解它们。
我不确定它是否与问题有关，但看起来奇怪的是，ParameterizedTypeImpl类中唯一的构造函数具有如下签名：private ParameterizedTypeImpl(java.lang.Class<?> aClass, java.lang.reflect.Type[] types, java.lang.reflect.Type type)，但堆栈跟踪中的签名看起来像是在接受ParameterizedTypeImpl本身：ParameterizedTypeImpl.<init>(ParameterizedTypeImpl.java:53)。
现在我被困住了;任何可以帮助我的建议都非常感谢。
