Serverless framework deploy for Java AWS Lambdas

The Serverless framework ‘serverless deploy’ deploys whatever .jar you have packaged and ready to go within your source project.

If you make local code changes but don’t re-build your .jar, serverless thinks you don’t have any changes to deploy:

$ serverless deploy
...
Serverless: Packaging service...
Serverless: Service files not changed. Skipping deployment...

If you’re building a maven-based project, ‘mvn clean package’ first, then run your ‘serverless deploy’.
