Issue #, if available:
This is part of an ongoing effort to improve the code samples across the Lambda developer guide.
Description of changes:
This pull request updates the s3-java sample to use the latest dependencies, most notably the AWS SDK v2. This change updates all dependencies in build.gradle and pom.xml along with the relevant code. It also generally refactors the code, and adds additional comments in both the code and README to explain more of what the function is doing.
To test these changes, I ran through all 6 of the scripts again from start to finish. All steps succeed, and upon manually checking the resulting scaled down image, the code still does what it's expected to do.
