Proguard - 找不到常见的超类 / java.lang.VerifyError
我们正在开发一个桌面应用程序。在使用以下配置标志对代码运行 ProGuard（版本 5.3.3）时：
-dontoptimize
-allowaccessmodification
-dontusemixedcaseclassnames
-dontwarn
Proguard 给出以下错误：
Unexpected error while performing partial evaluation:
Class = [com/code/backend/e/b/b]
Method = [b(Ljava/lang/String;)Ljava/nio/file/Path;]
Exception = [java.lang.IllegalArgumentException] (Can't find common super class of [com/google/common/collect/ImmutableList] (with 2 known super classes) and [com/google/common/collect/UnmodifiableIterator] (with 1 known super classes))
Unexpected error while preverifying:
Class = [com/code/backend/e/b/b]
Method = [b(Ljava/lang/String;)Ljava/nio/file/Path;]
Exception = [java.lang.IllegalArgumentException] (Can't find common super class of [com/google/common/collect/ImmutableList] (with 2 known super classes) and [com/google/common/collect/UnmodifiableIterator] (with 1 known super classes))
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task 'proguard'.
> Can't find common super class of [com/google/common/collect/ImmutableList] (with 2 known super classes) and [com/google/common/collect/UnmodifiableIterator] (with 1 known super classes)
如果将标志 -dontpreverify 添加到配置中，则生成将成功。但是，在运行 jar 文件时，我们会收到以下错误：
Error: A JNI error has occurred, please check your installation and try again

这可以通过使用 JVM 标志 -noverify 来避免。读取线程：
如果可能的话，我们希望避免这些“无验证”标志。
注意：即使添加
-dontobfuscate
-dontshrink
