如何替换 Android Gradle 构建文件中已弃用的 packagingOptions

Question

I have migrated to gradle 8 my android build.gradle files show

plugins {
    id 'com.android.application' version '8.1.0-alpha01' apply false
    id 'com.android.library' version '8.1.0-alpha01' apply false
    id 'org.jetbrains.kotlin.android' version '1.8.0' apply false
    id 'com.google.dagger.hilt.android' version '2.44.2' apply false
}

tasks.register('clean') {
    delete rootProject.buildDir
}

Now in my module gradle.build files packagingOptions is highlighted as deprecated

packagingOptions {
    resources {
        excludes += '/META-INF/{AL2.0,LGPL2.1}'
    }
}

I thought I had found this solution

packagingOptions {
    resources.excludes.add('/META-INF/{AL2.0,LGPL2.1}')
}

which does not work?!! what is the correct replacement for the deprecated packagingOptions exclude?

The version of android studio I am using is

Android Studio Giraffe | 2022.3.1 Canary 1

    external.system.auto.import.disabled=true
    ide.text.editor.with.preview.show.floating.toolbar=false
    ide.images.show.chessboard=true

Non-Bundled Plugins:
    com.android.aas (3.5.1)

This appears to fix it

packagingOptions.resources.excludes.add('/META-INF/{AL2.0,LGPL2.1}')

It doesn't say packaginOptions is deprecated:

https://developer.android.com/reference/tools/gradle-api/7.0/com/android/build/api/dsl/PackagingOptions

https://developer.android.com/reference/tools/gradle-api/8.0/com/android/build/api/dsl/PackagingOptions

It says excludes is deprecated:

It's interesting that the 7.0 docs include excludes ( https://developer.android.com/reference/tools/gradle-api/7.0/com/android/build/api/dsl/PackagingOptions#excludes:kotlin.collections.MutableSet ).

7.2 only has exclude ( https://developer.android.com/reference/tools/gradle-api/7.2/com/android/build/api/dsl/PackagingOptions#exclude(kotlin.String) ) but explains what to swap it with:

This function is deprecated. This method is deprecated. Use resources.excludes.add() or jniLibs.excludes.add() instead. Use jniLibs.excludes.add() for.so file patterns, and use resources.excludes.add() for all other file patterns.

Which is what you've done.

If you read the 8.0 docs and click through to resources.excludes https://developer.android.com/reference/tools/gradle-api/8.0/com/android/build/api/dsl/ResourcesPackagingOptions#excludes()

It gives an example:

The set of excluded patterns. Java resources matching any of these patterns do not get packaged in the APK.

Example: android.packagingOptions.resources.excludes += "**/*.exclude"

So you could try that. (which is looks like you have).

Are you sure its highlighted as deprecated, and not highlighted as incubating as written here in the 8.0 docs? https://developer.android.com/reference/tools/gradle-api/8.0/com/android/build/api/dsl/PackagingOptions
