# 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 |
