Building and Testing

Build a simple jar file

A simple jar file doesn't include the dependencies.

./gradlew application:build

The library-1.0.0.jar file should be in the same directory.

java -jar application-1.0.0.jar

Build a uber jar file

A uber jar includes the dependencies.

./gradlew application:uberJar

You just need to run the next command

java -jar application-1.0.0-uber.jar

The output for both jar files should be

The sum of first 5 natural numbers is 15.
The sum of first 5 even natural numbers is 30.
