## Setup and Running the Application in VS Code

Follow these steps to set up and run the AgriConnectFX application in Visual Studio Code:

### 1. Prerequisites

*   **Java Development Kit (JDK):** Ensure you have JDK 17 or newer installed on your system. You can download it from Oracle or OpenJDK.
*   **JavaFX SDK:** Download the JavaFX SDK (version 22 or compatible with your JDK) from the [OpenJFX website](https://openjfx.io/openjfx-docs/#install-javafx). Extract it to a known location on your computer (e.g., `C:\javafx-sdk-22` on Windows, `/opt/javafx-sdk-22` on Linux/macOS).

### 2. VS Code Extensions

Open VS Code and install the following extensions:

*   **Extension Pack for Java** by Microsoft (includes Language Support for Java, Debugger for Java, Maven for Java, etc.).

### 3. Project Setup

1.  **Create a New Maven Project:**
    *   Open the VS Code Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P`).
    *   Type `Maven: Create Maven Project` and select it.
    *   Choose `maven-archetype-quickstart`.
    *   Select a version (e.g., `1.4`).
    *   Enter `groupId`: `com.agriconnect`
    *   Enter `artifactId`: `AgriConnectFX`
    *   Confirm the project location.

2.  **Replace `pom.xml`:**
    *   Open the `pom.xml` file generated in your new `AgriConnectFX` folder.
    *   **Replace its entire content** with the `pom.xml` provided in the `CodeProject` block above.
    *   **Important:** In the `<dependencies>` section of `pom.xml`, ensure the `<classifier>` for `javafx-graphics` matches your operating system (`win`, `linux`, or `mac`). If you want to build for multiple OS, you can include multiple `<classifier>` entries.

3.  **Set up Source Folders and Files:**
    *   In your `AgriConnectFX` project, navigate to `src/main/java`.
    *   Delete any default Java files (e.g., `App.java`) that Maven might have created.
    *   Create the following package directories inside `src/main/java` to match the project structure:
        *   `Controller`
        *   `Dao`
    *   Place the respective `.java` files (e.g., `AppController.java`, `AuthService.java`) into their correct package folders as shown in the "Project Structure" above.
    *   `Main.java` should be placed directly under `src/main/java` (it's in the default package).
    *   Create a `src/main/resources` folder. Inside `resources`, create an `images` folder.
    *   Place the provided image files (`landing_background.jpg`, `login_background.jpg`, `signup_background.jpg`, `2909769.png`, `415744.png`, `rice.png`, `tomato.png`, `chilli.png`, `neem.png`) into `src/main/resources/images`.

4.  **Configure VS Code Settings (`.vscode` folder):**
    *   Copy the `.vscode` folder (containing `launch.json` and `settings.json`) from the `CodeProject` block above into the root of your `AgriConnectFX` project.
    *   **Crucially, open `.vscode/launch.json` and `.vscode/settings.json` and update the paths** to point to the actual location of your JavaFX SDK `lib` directory on your system. For example, replace `"C:\\path\\to\\javafx-sdk-22\\lib"` with your actual path.

### 4. Refresh Maven Dependencies

*   After updating `pom.xml` and adding files, VS Code should automatically detect changes and prompt you to "Synchronize" or "Reload" the Maven project.
*   If it doesn't, open the Command Palette (`Ctrl+Shift+P`) and run `Maven: Reload All Maven Projects`. This step is vital for VS Code to download and recognize all JavaFX dependencies.

### 5. Run the Application

There are a few ways to run the application:

*   **From `Main.java`:**
    *   Open the `src/main/java/Main.java` file in VS Code.
    *   You should see a green "Run" button (a triangle icon) next to the `public static void main(String[] args)` method. Click it.

*   **Using Maven Commands:**
    *   Open the Command Palette (`Ctrl+Shift+P`).
    *   Type `Maven: Execute Commands`.
    *   Select your `AgriConnectFX` project.
    *   Choose `clean` (to clean previous builds) and then `javafx:run` (to compile and run the application).

### 6. Testing the Application

Once the application launches:

*   **Login/Signup:** Use the "Login" or "Sign Up" buttons on the landing page.
    *   **Demo Credentials:**
        *   **Farmer:** Username: `farmer1`, Password: `pass123`
        *   **Dealer:** Username: `dealer1`, Password: `pass123`
        *   **Nursery:** Username: `nursery1`, Password: `pass123`
    *   You can also create new accounts via the "Sign Up" page.
*   **Dashboard Navigation:** After logging in, explore the sidebar navigation for each role (Farmer, Dealer, Nursery) to confirm that all sections load correctly and display their respective content.
*   **Functionality:** Test the simulated functionalities within each dashboard, such as "Get Advice" in Soil & Crop Advisor, "Upload Image" in Disease Detection, and "Send" messages in chat interfaces.

If you encounter any further issues, please double-check the JavaFX SDK path in your VS Code settings and ensure Maven has successfully downloaded all dependencies.</article></body></html>
