Class not found: helloworld.App

Hi, I tried to deploy this application to my AWS cloud. I encountered this error when I call the hello API.

{
  "errorMessage": "Class not found: helloworld.App",
  "errorType": "java.lang.ClassNotFoundException"
}

Class not found: helloworld.App: java.lang.ClassNotFoundException
java.lang.ClassNotFoundException: helloworld.App

I have found the solution. The CodeUri attribute in AWS::Serverless::Function resource written in template.yaml only works locally. It will require a different value for it to work on the AWS cloud.

For local build, use the API folder name.

CodeUri: HelloWorldFunction

For deployment build, it has to be the path to the jar file that is built by running this command, mvn clean package. Which in this case is

CodeUri: ./HelloWorldFunction/target/HelloWorld-1.0.jar
