```

This will put an executable JAR in `./target`, which can be run using:

```shell
java -jar target/*.jar
```

#### Using Docker

Build the JAR file as before and then execute the following command to extract the layers from the JAR:

```shell
mkdir target/extracted && java -Djarmode=layertools -jar target/*.jar extract --destination target/extracted
```

```shell
docker build -t bankingservice .
