Java混淆-使用proguard

Question

我正在使用oshi在我的应用程序中创建一个唯一的密钥。我已经从项目中创建了一个带有maven着色插件的胖罐子。这个肥罐子工作得很好，没有混淆。但是，如果我使用ProGuard混淆jar，则jar在尝试运行时会抛出以下错误。

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.sun.a.H.h()Ljava/lang/String;
at com.sun.a.H.h(Native Method)
at com.sun.a.H.<clinit>(Unknown Source)
at com.sun.a.ab.setAlignType(Unknown Source)

at com.pegado.qpguard.f.d.a(Unknown Source)
at com.pegado.qpguard.d.b.<clinit>(Unknown Source)
at com.pegado.qpguard.editor.Application.main(Unknown Source)

因此，我创建了一个proguard.confile来管理模糊规则。

-keep public class com.acme.qpguard.editor.Application { *; }
-keep class org.apache.log4j.** { *; }
-keep class oshi.hardware.** { *; }
-keep class oshi.util.** { *; }
-keep class oshi.software.** { *; }
-keep class oshi.SystemInfo { *; }

但这对我没有帮助。这个罐子仍然抛出java.lang.UnsisfiedLinkError，这是由oshi引起的。期待着找到解决这个问题的方法。提前谢谢。

我已将proguard.conf修改为：

-dontskipnonpubliclibraryclassmembers
-keepdirectories
-target 1.8
-forceprocessing
-dontoptimize
-allowaccessmodification
#-overloadaggressively
#-keeppackagenames org.**
-keepattributes *Annotation*
-verbose
-keep public class com.acme.qpguard.editor.Application { *; }
-keep class org.apache.logging.log4j.** { *; }
-keepattributes Signature,Annotation
-keep class org.sqlite.** { *; }
-keep class com.sun.** { *; }
-keep class com.google.** { *; }
-keep class oshi.** { *; }
-keep class com.acme.qpguard.logger.LoggerConstants { *; }
-keepclassmembers class com.acme.qpguard.logger.QPLogger {
QPLogger commonLoggerInstance;
}
-keep class com.acme.qpguard.logger.QPLogger { *; }
#
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keepattributes SourceFile,LineNumberTable
-dontwarn
# absolutely must keep this commented out for production
# -keepattributes SourceFile,LineNumberTable

这可能需要进一步的优化甚至修正，但暂时对我有用。谢谢
