Building with `--android_platforms=//:arm64` returns error.

[AnDevi]

I'm using bazel 7.0.2 right now. Compilation with command: bazel build //apps/playground-android --fat_apk_cpu=arm64-v8a --android_crosstool_top=@androidndk//:toolchain --noincompatible_enable_android_toolchain_resolution works fine.

But I'd like to build it with command: bazel build //apps/playground-android --android_platforms=//apps/playground-android:android_arm64_platform android_arm64_platform is defined like that:

platform(
    name = "android_arm64_platform",
    constraint_values = [
        "@platforms//cpu:arm64",
        "@platforms//os:android",
    ],
)

but unfortunately this command returns an error:

My WORKSPACE file looks like that (path to ANDROID_NDK_HOME is specified in env varaible) :

)

load("@rules_android_ndk//:rules.bzl", "android_ndk_repository")

android_ndk_repository(
    name = "androidndk",
    api_level = 33,
)

register_toolchains("@androidndk//:all")

Am I missing something in command or in my configuration ? Or what else could be problematic ?

@AnDevi I think this has been fixed in the latest commits in this repo.
