Question

这是我的错误信息：

Unexpected error while performing partial evaluation:
  Class       = [org/apache/log4j/chainsaw/Main]
  Method      = [<init>()V]
  Exception   = [java.lang.IllegalArgumentException] (Can't find common super class of [java/lang/NoClassDefFoundError] (with 5 known super classes) and [org/apache/log4j/chainsaw/LoadXMLAction] (with 1 known super classes))
Exception while processing task

如果我订 minifyEnabled true 这个错误来了，如果我订 minifyEnabled flase 我的proguardtask工作正常，

这是我的proguard.cfg文件：

-optimizationpasses 1
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-dontshrink
-verbose
-microedition
-ignorewarnings
-keepattributes InnerClasses,Signature
-keepattributes *Annotation*

所以，我不知道这个错误是如何发生的，这看起来是因为minifyEnabled工作错误，任何身体都遇到同样的问题。

当我在proguard.cfg中添加此行时，我的构建工作

`-dontoptimize`

但我不知道导致错误的原因

这可能是一个外部图书馆我挖了这个 http://sohu.io/questions/1918042/proguard-cant-find-any-super-classes 我确实有这样的情况：

由于编译包含Log4J的库，Proguard无法构建。获取该库的所有者以删除log4j并对其进行调用是我要采取的方法。特别是对于生产，因为proguard确实应该用于生产/发布场景......

Android使用gradle build with＆＃34; minifyEnabled true＆＃34;遇到错误，

`-dontoptimize`
