aws-java-simple-http-endpoint needs to updated/replaced for the current post 2.0.0 serverless framework

Tried using aws-java-simple-http-endpoint something like:

git clone https://github.com/serverless/examples.git
cd examples/aws-java-simple-http-endpoint
mvn package
npm init
.
.
.
npm install --save-dev serverless
alias serverless=./node_modules/serverless/bin/serverless.js
alias sls=./node_modules/serverless/bin/serverless.js
'edit serverless.yml to change artifact: build/distributions/aws-java-simple-http-endpoint.zip -> artifact: target/aws-java-simple-http-endpoint.jar'
sls invoke local -f currentTime

and get

  Serverless Error ---------------------------------------
 
  The Serverless version (2.21.1) does not satisfy the "frameworkVersion" (>=1.2.0 <2.0.0) in serverless.yml

  Your Environment Information ---------------------------
     Operating System:          darwin
     Node Version:              12.18.1
     Framework Version:         2.21.1 (local)
     Plugin Version:            4.4.2
     SDK Version:               2.3.2
     Components Version:        3.6.0

Start in examples/aws-java-simple-http-endpoint and inspect serverless.yml, especially the frameworkVersion and artifact settings. Reproduce the reported workflow with mvn package and sls invoke local -f currentTime using the current Serverless Framework. Done means the example is updated or replaced so it works with post-2.0.0 Serverless versions and the function can be invoked locally.
