Android Build Error: Attribute Signature requires InnerClasses attribute. Check -keepattributes directive
Android Build Error: Attribute Signature requires InnerClasses attribute. Check -keepattributes directive
我在尝试以发布模式构建应用程序时遇到此错误。
Error: Attribute Signature requires InnerClasses attribute. Check -keepattributes directive
我的 proguard-rules.pro 行如下所示：
-keepattributes Signature
编译器指的是什么内部类？我遗漏了什么？
Signature（Java 8 或更高版本）仅适用于 Java 8 或更高版本和 InnerClasses（Java 5 或更高版本），因此请检查您的 Android Studio 是否正在使用 Java SDK版本。
请使用以下设置更新您的 Proguard 配置
将此行添加到您的 proguard-rules.pro 文件中：
-keepattributes InnerClasses
InnerClasses (Java 5 or higher)
Specifies the relationship between a class and its inner classes and
outer classes. Other than this and the naming convention with a '$'
separator between the names of inner classes and outer classes, inner
classes are just like ordinary classes. Compilers may need this
information to find classes referenced in a compiled library. Code may
access this information by reflection, for instance to derive the
simple name of the class.
Signature (Java 8 or higher)
Specifies the generic signature of the class, field, or method.
Compilers may need this information to properly compile classes that
use generic types from compiled libraries. Code may access this
signature by reflection.

keepattributes [attribute_filter]
Specifies any optional attributes to be preserved. The attributes can
be specified with one or more -keepattributes directives. The optional
filter is a comma-separated list of attribute names. Attribute names
can contain ?, *, and ** wildcards, and they can be preceded by the !
negator. Typical optional attributes are Exceptions, Signature,
Deprecated, SourceFile, SourceDir, LineNumberTable,
LocalVariableTable, LocalVariableTypeTable, Synthetic,
EnclosingMethod, RuntimeVisibleAnnotations,
RuntimeInvisibleAnnotations, RuntimeVisibleParameterAnnotations,
RuntimeInvisibleParameterAnnotations, and AnnotationDefault. The
InnerClasses attribute name can be specified as well, referring to the
source name part of this attribute. For example, you should at least
keep the Exceptions, InnerClasses, and Signature attributes when
processing a library. You should also keep the SourceFile and
LineNumberTable attributes for producing useful obfuscated stack
traces. Finally, you may want to keep annotations if your code depends
on them. Only applicable when obfuscating.
