Version of Gradle Plugin: 7.0.0-alpha13

Version of Gradle:6.8.3

Version of Java: openjdk 11.0.9

After upgrading AGP to alpha13, we cannot disable AGP's built-in resource optimization:

An exception occurred applying plugin request [id: 'com.android.application']
> Failed to apply plugin 'com.android.internal.application'.
   > The option 'android.enableResourceOptimizations' is deprecated.
     The current default is 'true'.
     It was removed in version 7.0 of the Android Gradle plugin.

Previously, we used the following code for our own optimization, because AGP could not meet our needs.

val optimizeReleaseRes = task("optimizeReleaseRes").doLast {
    val aapt2 = Paths.get(
        project.android.sdkDirectory.path,
        "build-tools",
        project.android.buildToolsVersion,
        "aapt2"
    )
    val mapping = Paths.get(
        project.buildDir.path,
        "outputs",
        "mapping",
        "release",
        "shortening.txt"
    )
    val zip = Paths.get(
        project.buildDir.path,
        "intermediates",
        "shrunk_processed_res",
        "release",
        "resources-release-stripped.ap_"
    )
    val optimized = File("${zip}.opt")
    val cmd = exec {
        commandLine(
            aapt2, "optimize",
            "--collapse-resource-names",
            "--enable-sparse-encoding",
            "--shorten-resource-paths",
            "--resource-path-shortening-map", mapping,
            "-o", optimized,
            zip
        )
        isIgnoreExitValue = false
    }
    if (cmd.exitValue == 0) {
        delete(zip)
        optimized.renameTo(zip.toFile())
    }
}

tasks.whenTaskAdded {
    if (name == "shrinkReleaseRes") {
        finalizedBy(optimizeReleaseRes)
    }
}

AGP does not save the map when shortening the resource path, which makes us have to disable it, and also, AGP cannot do other optimizations like sparse encoding. After alpha13. AGP forces enable shorten-resource-paths, but aapt2 shortening twice will break the apk to make it impossible to open. If we stop shortening the resource paths ourselves, AGP won't save the resource path shortening map, there is no solution anyway. We want AGP to support all the parameters in the aapt2 optimization (which is already partially supported inside AGP, but does not allow us to configure it), and until then, stop forcing enabled shorten-resource-paths.
