问题
I have been trying to use the latest JACK and JILL build system to for my android project. I know that JACK process includes the proguard processing.
But after that i couldn't locate the mappings.txt file for back-tracking stack-trace of bugs provided on google play developer console.
Please help me LOCATE mappings.txt.
Another related question is if the shrinkingResources still works while JACK because shrinkingResources requires minifyEnabled true but JACK requires minifyEnabled false.
Project Config--
compileSdkVersion 24
buildToolsVersion "24.0.0"
classpath 'com.android.tools.build:gradle:2.1.2'
UPDATE--
Answer posted by T. Neidhart is NOT a working solution.
回答1:
To enable obfuscation/shrinking with JACK you need to set minifyEnabled to true. It was unsupported in earlier versions, but now JACK has its own obfuscation and shrinking implementation (not using ProGuard at all) that can process some of the original ProGuard rules (for a complete list of supported options refer to Jack obfuscation and shrinking).
Once the configuration is properly setup, the mapping.txt file will be located in the same place as before: build/outputs/mapping/<buildtype>/mapping.txt
回答2:
There is nowhere to find that mappings file as JACK internally process proguard and there are some issues pointed on android tools site while enabling JACK.
So for now not using JACK is the best option if you care tracing back exceptions in your apps.
