# new-shapes
A shape editor desktop application built with Java Swing. Supports rectangles, circles, triangles, text, shape collections, resize handles, and export to HTML/SVG.
## Prerequisites
- JDK >= 16 (project targets Java 16)
- A graphical display (X11/Wayland) since this is a Swing GUI application
## Bootstrap
### With Nix (recommended)
```sh
nix develop
```
This drops you into a shell with JDK 17 and Maven 3.9.x preconfigured. No other setup needed.
### Without Nix
Install JDK 16+ and use the bundled Maven wrapper — no separate Maven installation required:
```sh
./mvnw --version # downloads Maven 3.9.12 on first run
```
## Run the application
```sh
./mvnw compile exec:java -Dexec.mainClass="ovh.gasser.newshapes.App"
```
## Run tests
```sh
./mvnw test
```
To run the full verification pipeline (compile, test, JaCoCo coverage check with 50% minimum line coverage):
```sh
./mvnw verify
```
Coverage reports are generated in `target/site/jacoco/`.
