Không thể xây dựng bản phát hành trong Kotlin

Question

Sau khi chuyển đổi dự án Android của tôi thành Kotlin Tôi không thể xây dựng bản phát hành, lỗi xuất hiện liên quan đến Proguard.

Tôi thấy 155 cảnh báo như

Warning:com.example.app.activity.MainActivity$1: can't find referenced field 'android.view.View decorView' in program class com.example.app.activity.MainActivity 
Warning:com.example.app.activity.MainActivity$2: can't find referenced field 'android.os.Handler handler' in program class com.example.app.activity.MainActivity 

và xây dựng không thành công với

Error:Execution failed for task ':MyApp:transformClassesAndResourcesWithProguardForFreeRelease'. 
> Job failed, see logs for details 

Nếu tôi thay đổi các chỉ thị trong build.grade từ true sang false xây dựng thành công.

minifyEnabled true 
shrinkResources true 

Bất kỳ đề xuất nào về vấn đề này có thể là gì?

Edit:

Các tập tin Proguard dưới:

Proguard-android.txt

# This is a configuration file for ProGuard. 
# http://proguard.sourceforge.net/index.html#manual/usage.html 

-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-verbose 

# Optimization is turned off by default. Dex does not like code run 
# through the ProGuard optimize and preverify steps (and performs some 
# of these optimizations on its own). 
-dontoptimize 
-dontpreverify 

# If you want to enable optimization, you should include the 
# following: 
# -optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/* 
# -optimizationpasses 5 
# -allowaccessmodification 
# 
# Note that you cannot just include these flags in your own 
# configuration file; if you are including this file, optimization 
# will be turned off. You'll need to either edit this file, or 
# duplicate the contents of this file and remove the include of this 
# file from your project's proguard.config path property.

Cố gắng tạo bản dựng mà không có người bảo vệ để từ chối người chịu trách nhiệm về vấn đề đó.
