Several files and a folder hierarchy are created. This includes a simple “Hello World” program.
To test, build and run your code execute in the root of the project:
```
 $ ./gradlew run
```
The program is run after the output:
```
 > Task :run
```

To clean the project directory:
```
  $ ./gradlew clean
```
