Gradle build error for Android: Aborting build initialization due to existing files in the project directory: .../build/android

What OS are you using (uname -a, or Windows version)?

$ uname -a
Linux hostess 6.12.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 27 Dec 2024 14:24:37 +0000 x86_64 GNU/Linux

What version Socket Runtime are you using?

$ bun run ssc -v
0.6.0-rc.8 (7419e97a)
Installation path: /home/narilth/HPK/projects/simple-record/node_modules/@socketsupply/socket-linux-x64/

What programming language are you using (C/C++/Go/Rust)?

I don't think I'm using any of these compilers...
For my actual project I'm using Javascript (Vite, Typescript, SolidJS)

gcc (GCC) 14.2.1 20240910
clang version 18.1.8
go version go1.23.4 linux/amd64
rustc 1.68.0 (2c8cc3432 2023-03-06)
node -v: v23.4.0

What did you expect to see and what you saw instead?

I have an existing (very simple) application that targets Linux. Now, I want to also target Android.

I'm following the Android build guide on https://socketsupply.co/guides/#mobile-guides_android.

1. I ran ssc setup --platform=android.
2. I verified that my .ssc.env contains the right paths. Below is the output of bun run ssc env.

ANDROID_HOME=/home/narilth/Android/Sdk
CXX=/sbin/clang++
GRADLE_HOME=/usr/share/java/gradle
HOME=/home/narilth
JAVA_HOME=/usr/lib/jvm/default
LANG=en_US.UTF-8
PREFIX=/home/narilth/HPK/projects/simple-record/node_modules/@socketsupply/socket-linux-x64
PWD=/home/narilth/HPK/projects/simple-record/ui
SHELL=/usr/bin/zsh
SOCKET_HOME=/home/narilth/HPK/projects/simple-record/node_modules/@socketsupply/socket-linux-x64/
SOCKET_HOME_API=/home/narilth/HPK/projects/simple-record/node_modules/@socketsupply/socket
USER=narilth

3. I plugged in my Android device and went through the USB Debugging steps. ssc list-devices --platform=android returns a serial number, as expected.
4. I ran bun run ssc build -r --platform=android (I also tried -r -o --platform=android, --platform=android, --platform=android-emulator). I get the following error.

$ (export VERBOSE=1; bun run ssc build -o --platform=android)
• cd /home/narilth/HPK/projects/simple-record/ui/build/android +10ms
• sdkmanager --version 2>&1 >/dev/null +0ms
• echo 1 |/usr/share/java/gradle/bin/gradle --no-configuration-cache --no-build-cache --no-scan --offline --quiet init +1682ms

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':init'.
> Aborting build initialization due to existing files in the project directory: '/home/narilth/HPK/projects/simple-record/ui/build/android'.

* Try:
> Remove any existing files in the project directory and run the init task again.
> Enable the --overwrite option to allow existing files to be overwritten.
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
> Get more help at https://help.gradle.org.

5. I tried checking my licenses. Below is the output. There are some warnings. After checking licenses, I still get the same error on build.

6. I tried rerunning the setup. Below is the output. After rerunning setup, I still get the same error on build.

$ bun run ssc setup --platform=android
