This demo assumes that you know the basics of Gradle (Please look at gradle for more info)
- clone this repo
cd Pf4jSpringGreetingDemo- run
./gradlew build - optionally, put some plugins in the './plugins' directory. This one for example
- Run
./gradlew bootRun
- The demo's output should look similar to:
