Tworzę kompilację o różnych smakach z Gradle. Do tej pory działało całkiem dobrze, dopóki nie chciałem włączyć Proguard
. Włączyłem minifyEnabled
dla mojej produkcji o prawach i teraz mam takie powiedzenie wyjątek:Android Build z Gradle i ProGuard: "Słoik wyjściowy musi zostać określony za słojem wejściowym lub będzie pusty"
„Caused by: org.gradle.internal.UncheckedException: java.io.IOException: The output jar [.../app/build/intermediates/multi-dex/dev/release/componentClasses.jar] must be specified after an input jar, or it will be empty.
”
Czy ktoś wie, co jest przyczyną tego wyjątku? Zasadniczo chcę włączyć ProGuard przed wydaniem mojej aplikacji. Oto mój plik Gradle poniżej.

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /Users/osayilgan/Development/Android/sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;

-keepnames public class * extends io.realm.RealmObject
