# Build and install

> Build a Plex module and install it on a server

Source: https://plex.us.org/docs/create_module/install/

1. Build the module with Gradle.

   ```bash
   ./gradlew build
   ```

2. The JAR is in `build/libs/`. Copy it into the `plugins/Plex/modules/` folder on your server.

3. Restart the server. Plex reads the new module and enables it.

On Paper, you can also run `/plex modules reload` in game. Do not use reload if the module needs new libraries, because Plex downloads libraries only when the server starts. On Folia, you must restart the server.

You can also manage modules in game.

| Command                                   | Description                                                    |
| ----------------------------------------- | -------------------------------------------------------------- |
| `/plex modules`                           | Lists the loaded modules.                                      |
| `/plex modules install <name>`            | Downloads and installs an official module by name.             |
| `/plex modules update`                    | Updates every module that the updater manages.                 |
| `/plex modules reload`                    | Reloads all modules from disk.                                 |
| `/plex modules uninstall <name> [-rmdir]` | Removes a module. Add `-rmdir` to also delete its data folder. |

## Updater metadata

By default, Plex updates a module through its first-party updater, which serves the official modules. A third-party module should set its own `updater.url` or turn updates off. You control this behavior with an optional `updater` block in `module.yml`.

```yaml title="module.yml"
updater:
  enabled: true
  url: https://updates.example.com/module-example
```

Set `enabled` to `false` to remove the module from `/plex modules update`. Set `url` to serve updates from your own location instead of the first-party updater. Use `urls` with a list if you serve from more than one location.

```yaml title="module.yml"
updater:
  enabled: false
```
