Description

When I am using Proguard, i run into this issue: ERROR: R8: Library class java.util.AbstractCollection implements program class java.util.Collection ERROR: R8: Library class java.util.AbstractList implements program class java.util.List ERROR: R8: Library class java.util.AbstractMap$SimpleImmutableEntry implements program class java.util.Map$Entry ERROR: R8: Library class java.util.AbstractMap implements program class java.util.Map ERROR: R8: Library class java.util.ArrayList implements program class java.util.List ERROR: R8: Library class java.util.AbstractSet implements program class java.util.Set ERROR: R8: Library class java.util.Hashtable implements program class java.util.Map ERROR: R8: Library class java.util.LinkedHashMap implements program class java.util.Map ERROR: R8: Library class java.util.HashMap implements program class java.util.Map ERROR: R8: Library class java.util.concurrent.CopyOnWriteArrayList implements program class java.util.List ERROR: R8: Library class java.util.TreeMap implements program class java.util.NavigableMap ERROR: R8: Library class java.util.LinkedList implements program class java.util.List ERROR: R8: Library class java.util.LinkedList implements program class java.util.Deque ERROR: R8: Library class java.util.HashSet implements program class java.util.Set ERROR: R8: Library class java.util.ArrayDeque implements program class java.util.Deque ERROR: R8: Library class java.util.WeakHashMap implements program class java.util.Map ERROR: R8: Library class java.util.LinkedHashSet implements program class java.util.Set ERROR: R8: Library class java.util.concurrent.LinkedBlockingQueue implements program class java.util.concurrent.BlockingQueue ERROR: R8: Library class java.util.AbstractQueue implements program class java.util.Queue ERROR: R8: Library class java.util.concurrent.ConcurrentLinkedQueue implements program class java.util.Queue ERROR: R8: Library class java.util.ServiceLoader implements program class java.lang.Iterable ERROR: R8: Library class java.util.TreeSet implements program class java.util.NavigableSet ERROR: R8: Library class java.util.concurrent.ConcurrentSkipListMap implements program class java.util.concurrent.ConcurrentNavigableMap ERROR: R8: Library class java.util.concurrent.SynchronousQueue implements program class java.util.concurrent.BlockingQueue ERROR: R8: Library class java.util.AbstractMap$SimpleEntry implements program class java.util.Map$Entry ERROR: R8: Library class java.nio.file.Path implements program class java.lang.Iterable ERROR: R8: Library class java.util.IdentityHashMap implements program class java.util.Map

Then when i add this to my proguard: -dontwarn java.util. -dontwarn java.nio.file. -dontwarn java.lang.Iterable -keep class java.util.* { ; } -keep class java.nio.file.* { ; } -keep class java.lang.Iterable { *; }

Reproducing the issue

Code:

gradle-wrapper.properties: distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-bin.zip

proguard-rules.pro:

Add project specific ProGuard rules here.

By default, the flags in this file are appended to flags specified

in the {sdk.dir}/tools/proguard/proguard-android.txt file

You can edit the include path and order by changing the ProGuard

include property in project.properties.

For more details, see

http://developer.android.com/guide/developing/tools/proguard.html

Add any project specific keep options here:

Flutter specific

Suppress warnings for the device_info_plus library, specifically for Build.getSerial()

-dontwarn dev.fluttercommunity.plus.device_info.MethodCallHandlerImpl

Suppress all warnings for the device_info_plus package

-dontwarn dev.fluttercommunity.plus.device_info.**

-dontwarn java.util. -dontwarn java.nio.file. -dontwarn java.lang.Iterable -keep class java.util.* { ; } -keep class java.nio.file.* { ; } -keep class java.lang.Iterable { *; }

Hi @itismejy . Kindly provide a minimal code sample reproducing this issue

Lyokone commented 1 week ago

Closing since it looks like a Proguard misconfiguration and not related to FF.
