Proguard-找不到任何超级类 [英] Proguard - Can't find any super classes

问题描述

我收到此错误:

Unexpected error while performing partial evaluation:
Class       = [org/apache/log4j/chainsaw/Main]
Method      = [<init>()V]
Exception   = [java.lang.IllegalArgumentException] (Can't find any super classes of [org/apache/log4j/chainsaw/LoadXMLAction] (not even immediate super class [javax/swing/AbstractAction]))
Error: Can't find any super classes of [org/apache/log4j/chainsaw/LoadXMLAction] (not even immediate super class [javax/swing/AbstractAction])

我的proguard配置的一部分:

Part of my proguard configuration:

-dontwarn javax.jms.**
-dontwarn com.sun.jdmk.comm.**
-dontwarn android.support.v4.**

有用于log4j的库，那么可能是什么问题?

The library for log4j is there, so what could be the problem?

更新

我发现优化过程中出现了问题. 收缩和混淆正在起作用.

As I have found the problem is raised during optimalization. Shrink and obfuscation is working.

推荐答案

对于那些需要在Android上使用Log4J的快速解决方案的人，Krivers的更新实际上是一个提示:在ProGuard配置中设置-dontoptimize会关闭优化并从而避免了该错误(尽管这仅应被视为一种解决方法).

For those who need a fast solution on using Log4J on Android, Krivers' update actually served as a hint: setting -dontoptimize in ProGuard configuration turns off optimization and thus avoids the error (although this should only be considered as a workaround).

实际上，Android Tools项目站点还具有建议关闭ProGuard优化:

In fact, the Android Tools Project Site had also suggested to turn off ProGuard optimization:

Dalvik执行许多自身的优化，并且ProGuard进行的某些优化与Dalvik不兼容，因此为避免难以理解的错误(并且由于净性能增益通常很小)，默认配置关闭优化.

Dalvik performs many of its own optimizations, and some of the optimizations performed by ProGuard are incompatible with Dalvik, so to avoid hard-to-figure-out bugs (and because the net performance gain is usually small), the default configuration turns off optimization.
