Authoring Lambda Functions Using Eclipse IDE and AWS SDK Plugin (Java)

AWS SDK Eclipse Toolkit provides an Eclipse plugin for you to both create a deployment package and also upload it to create a Lambda function. If you can use Eclipse IDE as your development environment, this plugin enables you to author Java code, create and upload a deployment package, and create your Lambda function. For more information, see the AWS Toolkit for Eclipse Getting Started Guide. For an example of using the toolkit for authoring Lambda functions, see Using AWS Lambda with the AWS Toolkit for Eclipse.
