Thanks for the report!

I found there is a typo in your configuration:

# keep names of exception classes
-keepname class * extends java.lang.Throwable

which should be "keepnames".

We had a similar issue previously: issue 113122600.

But, I'm not able to repro the error. Without correcting the typo, I got:

$ java -jar build/libs/r8.jar --pg-conf ~/Downloads/proguard-rules.pro 
Error in /usr/local/google/home/jsjeon/Downloads/proguard-rules.pro at line 2, column 6:
Expected [!]interface|@interface|class|enum
Compilation failed

which looks like the correct line/column numbers now.

Thanks!

I'm using at least two proguard files on input like
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

I will try to reproduce it on some small test project.

One more note, after fix the typo, it crashed again on this

...\lib-about\build\intermediates\consumer_proguard_file\avastRelease\mergeAvastReleaseConsumerProguardFiles\proguard.txt:7:7: D8: Expected [!]interface|@interface|class|enum

This file looks like
1| -optimizations code/removal/simple,code/removal/advanced
2| -keepattributes SourceFile,LineNumberTable
3| -dontwarn **
4|
5| -keep class com.google.android.gms.common.GoogleApiAvailability { *; }
6| -keepname class com.actionbarsherlock.app.ActionBar
7| -keepname class com.viewpagerindicator.PagerIndicator
8| -keepname class com.nineoldandroids.view.ViewHelper
9| -keepname class com.jakewharton.disklrucache.DiskLruCache

It is the same issue.
But, again it should be line 6 instead of 7.
And also it should prefer path \lib-about\proguard-rules.pro instead of build/intermediates right?

It looks like for every project module declared like
implementation project(':lib-about')
it displays errors inside of build folder instead of the project file.
But in main app module, it works correctly.

And also would be great if it will display something like "unknown switch xyz" instead of Expected [!]interface|@interface|class|enu ;-)
