This is boilerplate code for a Java lambda function. To deploy this function code, to an actual lambda you must:

1. Run mvn package. It will build your poject and generate a JAR file in a /target directory at the root of the package called lambda-jar-jar-with-dependencies.jar
2. In the AWS console, create a Lambda function. Pick Java 11 as the language and click Create.
3. Once created, in the Source Code tab, click on upload and upload the JAR generate in the /target directory
4. Once uploaded, click on Edit in the Runtime settings and point the Handler to the correct class/function (Which is fares.lambda.java.HelloWorld::handleRequest)
5. Hit Save, and all done! You should be able to execute the code
