Cannot Deploy Sample Alexa Skill using Lambda

Question

I'm trying to deploy the Alexa HelloWorld Skill from the samples project here: https://github.com/amzn/alexa-skills-kit-java, on commit b58bfa641c7d58c476b80a4e8dd5ccbe0f9b2c40.

Per the README I run:

mvn assembly:assembly -DdescriptorId=jar-with-dependencies package

and upload the resulting alexa-skills-kit-samples-1.0-jar-with-dependencies.jar to the Lambda console. When I try to test the Lambda (in the web console) I get:

START RequestId: fe219281-be67-11e5-b15e-d79134e05828 Version: $LATEST

What am I missing?

Answer 1

I was also getting the same error.

It seems we need to run the mvn command within the directory"alexa-skills-kit-java-master\samples" and not from "alexa-skills-kit-java-master".

JAR created under "alexa-skills-kit-java-master\samples\target" has the helloworld class and I was able to successfully test the skill.
