Docker build failed

Describe the bug Failed to build from source using docker

To Reproduce Steps to reproduce the behavior:

1. cd core/src/main/rust/shadowsocks-rust
2. rustup target add armv7-linux-androideabi aarch64-linux-android i686-linux-android x86_64-linux-android
3. Run in root directory docker run --rm -v ${PWD}:/build -w /build shadowsocks/android-ndk-go ./gradlew assembleDebug
4. Errors like

Configuration

Additional context I am building on macos using docker

A workround: skip step 1 and 2

Add Script docker-exec.sh in root project dir

#!/bin/sh

cd core/src/main/rust/shadowsocks-rust
rustup target add armv7-linux-androideabi aarch64-linux-android i686-linux-android x86_64-linux-android

cd /build/
./gradlew assembleDebug

Then

docker run --rm -v ${PWD}:/build -w /build shadowsocks/android-ndk-go /build/docker-exec.sh

Builded success on mobile Apk

Addition If failed in resolve rust dependence, you may want to add to core/src/main/rust/shadowsocks-rust/.cargo/config.toml

[source.crates-io]
replace-with = 'tuna'

[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"
