[FIXED] Use consumerProguardFiles in my AAR library and get file not found while using obfuscationdictionary

Issue

In my library i use consumerProguardFiles in release build type. My proguard role is :

-obfuscationdictionary proguard-dictionary.txt
-classobfuscationdictionary proguard-dictionary.txt
-packageobfuscationdictionary proguard-dictionary.txt

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose
-dump class_files.txt
-printseeds seeds.txt
-printusage unused.txt
-printmapping mapping.txt
-optimizations !code/simplification/arithmetic,!field/removal/writeonly,!field/marking/private,!class/merging/*,!code/allocation/variable
-flattenpackagehierarchy
-allowaccessmodification
-renamesourcefileattribute SourceFile
-keepattributes *Annotation*
-keepattributes Signature,MethodParameters,LocalVariableTable,LocalVariableTypeTable
-keepattributes SourceFile,LineNumberTable
-keepattributes Exceptions,InnerClasses

When developers use my library (AAR) in the project and getting release build and use minifyEnabled true, get proguard-dictionary.txt is not found:

AGPBI: {"kind":"error","text":"File not found: /Users/USER/.gradle/caches/transforms-2/files-2.1/12e928515abf78e8a4387fd92c3a399b/proguard-dictionary.txt","sources":[{"file":"/Users/USER

How can I use -obfuscationdictionary without using a dictionary file? or How can I fix this?

Solution

Use the following code:

buildTypes {
        debug {
            minifyEnabled false
            debuggable true
        }
        release {
            minifyEnabled true
            debuggable false
            // automatically add your proguard rules into your library user
            consumerProguardFiles 'proguard-rules.pro'
            proguardFiles 'proguard-rules-dic.pro', 'proguard-rules.pro'
        }
}
