One of the key aspects of AWS Lambda Function in Java is creating deployment package (jar or zip file) for uploading/deploying on AWS Lambda service. In this post, you will learn about different ways in which you could create a Deployment Jar file for deploying it as AWS Lambda project using Maven. The following are different ways:
I recommend using Maven and commmand prompt technique for creating deployment jar package.
Before getting started, download AWS Toolkit for Eclipse from Eclipse Marketplace. Here is the information on getting setup with AWS Toolkit for Eclipse
The following are steps required to create a AWS Lambda deployment jar file using Eclipse IDE and Maven:
