# PF4J Gradle Demo

This demo assumes that you know the basics of Gradle (Please look at [gradle](https://gradle.org/) for more info)

### Setup/Build

1. Clone the repo
2. Go to demo_gradle `cd demo_gradle` 
3. run `gradle build`

* This will produce one jar, named app-plugin-demo-uberjar.jar, located in the `app/build/libs/` directory and three plugins zips located in `build/plugins` directory.
* The plugins are `plugin-hello-plugin-0.0.1.zip`,  `plugin-KotlinPlugin-1.0.0.zip` and `plugin-welcome-plugin-0.0.1.zip`

### Run the demo

1. Run 

```
 java -jar -Dpf4j.pluginsDir=build/plugins app/build/libs/app-plugin-demo-uberjar.jar 
```

* pf4j.pluginsDir: is where the plugins are located

2. The demo's output should look similar to: (Please see `Boot#main()` for more details)
```
demo_gradle $ java -jar -Dpf4j.pluginsDir=build/plugins app/build/libs/app-plugin-demo-uberjar.jar
