# Jet File Transfer
Jet File Transfer lets you share files and folders between devices on the same local network without using the internet. Launch one device as a server and another as a client — they discover each other automatically.

## Download
Pre-built packages are published on [GitHub Releases](https://github.com/erdemkosk/jet-file-transfer/releases):
| Platform | File |
|----------|------|
| macOS (Apple Silicon) | `JetFileTransfer-macos-aarch64.dmg` |
| macOS (Intel) | `JetFileTransfer-macos-x64.dmg` |
| Windows | `JetFileTransfer-windows-x64.zip` |
| Linux | `JetFileTransfer-linux-x64.tar.gz` |
Release builds include a bundled Java runtime — **you do not need to install Java** to run the desktop app.
---
## macOS installation
1. Download the DMG for your Mac from GitHub Releases:
- Apple Silicon (M1/M2/M3): `JetFileTransfer-macos-aarch64.dmg`
- Intel Mac: `JetFileTransfer-macos-x64.dmg`
2. Open the DMG and drag **Jet File Transfer** into **Applications**.
3. Run the commands below before the first launch.
### Why do I need to run a terminal command?
macOS **Gatekeeper** blocks apps downloaded from the internet when they are not signed and notarized by Apple. Our open-source builds are ad-hoc signed, so macOS may show:
> *"Apple cannot verify that JetFileTransfer is free of malware"*
This does **not** mean the app is malicious. It only means Apple has not reviewed the build. Removing the quarantine flag tells macOS you trust this download:
```bash
xattr -cr /Applications/JetFileTransfer.app
open /Applications/JetFileTransfer.app
```
**Alternative (no terminal):** try opening the app once, then go to **System Settings → Privacy & Security** and click **Open Anyway**.
> A fully signed and notarized build (no warning, no extra steps) requires an Apple Developer account. That may be added in a future release.
---
## Windows installation
1. Download `JetFileTransfer-windows-x64.zip`.
2. Extract the archive.
3. Run `JetFileTransfer/JetFileTransfer.exe`.
If SmartScreen shows a warning, click **More info → Run anyway** — the app is unsigned, which is common for open-source releases.
---
## Linux installation
1. Download `JetFileTransfer-linux-x64.tar.gz`.
2. Extract the archive:
```bash
tar -xzf JetFileTransfer-linux-x64.tar.gz
```
3. Run the launcher:
```bash
./JetFileTransfer/bin/JetFileTransfer
```

## Requirements
### End users (release builds)
| | |
|---|---|
| **Java** | Not required — bundled in the release package |
| **Network** | Local network (Wi‑Fi / LAN). Internet is not used for file transfer |
| **macOS** | Apple Silicon or Intel (download matching DMG). See [macOS installation](#macos-installation) above |
| **Windows** | 64-bit Windows 10 or later |
| **Linux** | 64-bit Linux with glibc (most modern distros) |
### Developers (building from source)
| | |
|---|---|
| **Java** | **JDK 17** or later |
| **OpenJFX** | **17.0.12** (pulled automatically via Maven) |
| **Maven** | 3.6+ |
| **Python** | 3 + Pillow (optional, only to regenerate app icons) |
Since JDK 11, JavaFX is no longer bundled with the JDK. This project uses [OpenJFX](https://openjfx.io/) as a Maven dependency, so you do not need a separate JavaFX SDK install for development.
### Run from source
```bash
git clone https://github.com/erdemkosk/jet-file-transfer.git
cd jet-file-transfer
mvn clean javafx:run
```
### Build a local package
```bash
mvn clean package -Djavafx.platform=mac-aarch64 # macOS Apple Silicon
mvn clean package -Djavafx.platform=win # Windows
mvn clean package -Djavafx.platform=linux # Linux
```
Platform packages are created with `jpackage` in CI. See [`.github/workflows/release.yml`](.github/workflows/release.yml) for the full pipeline.
