Running the test applications

Each directory under the chapter directory represents a separate Gradle project. An executable .jar file can be built using:

// macOS
./gradlew clean build

// Windows
gradle clean build

The application can then be run using:

// macOS
java -jar ./build/libs/[application-name].jar

// Windows
java -jar .\build\libs\[application-name].jar
