Example failure: aws-java-simple-http-endpoint

Hi,

I followed the instruction as per the README for https://github.com/serverless/examples/tree/master/aws-java-simple-http-endpoint but these results in errors.

I'm specifically looking for an example that doesnt use maven with the shade plugin, but I've been unable to find a single working example.

Any advice/suggestions would be appreciated.

Regards

{"message": "Internal server error"}

Start by reading README.md, build.gradle, pom.xml, serverless.yml, and the src directory in aws-java-simple-http-endpoint. Run ./gradlew build followed by sls deploy and sls invoke --function currentTime --log to reproduce the ClassNotFoundException. Done means the example deploys and the currentTime invocation succeeds without that error.
