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

[terrybondy]

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

Hello @terrybondy :wave: Thanks a lot for reporting that issue, that's indeed the case and the example needs to be updated. We'd be more than happy to accept a PR for that improvement :tada:

[terrybondy]

Sorry, I can’t. A little too far down the rabbit hole for me. I’m having a problem with latest serverless with a simple ‘hello world’-like maven built java package and was looking for an example that should work.

Just getting started using serverless for real work with Java after dabbling with it last November with python. So far having a bad ‘out-of-the-box’ experience with serverless. ☹

That's totally understood @terrybondy :100: I'm sorry to hear that - did you by any chance try using one of the templates such as aws-java-maven? What are the issues that you're experiencing? To be honest, some of the tooling and examples around Java might be a bit outdated as JS and Python are leading languages in the space. I'd love to hear what issues are your running into

[terrybondy]

Well, seeing as you have asked, and realizing this is unrelated to the above issue.

Doing this:

mkdir simple-http
cd simple-http
npm init
.
.
.
npm install --save-dev serverless
alias serverless=./node_modules/serverless/bin/serverless.js
alias sls=./node_modules/serverless/bin/serverless.js
sls create --help
sls create -t aws-java-maven
mvn package
<edit serverless.yml to look like attached serverless.txt file (can't attach .yml for some reason)
[serverless.txt](https://github.com/serverless/examples/files/5894971/serverless.txt)
>
export SLS_DEBUG=*
sls invoke local -f hello --log

produces the following output for the last step:

I know it's a bit unrelated, but I was curious about what issues you're experiencing so we can better understand our shortcomings when it comes to improving experience for people trying Serverless Framework. In the above example, I'm not JVM expert, but I believe that instead of mvn package you should run mvn install - it seems like the target jar isn't available for local invocation

[terrybondy]

I will try that then.

Then also a problem with https://github.com/serverless/examples/blob/master/aws-java-simple-http-endpoint/README.md that will hopefully get fixed as part of this issue.

[terrybondy]

Same output as reported above after using these commands:

mvn clean install
sls invoke local -f hello --log

[terrybondy]

serverless.yml now looks like:

service: simple-http
frameworkVersion: '2'

provider:
  name: aws
  runtime: java8

package:
  artifact: target/hello-dev.jar

functions:
  hello:
    handler: com.serverless.Handler
    events:
      - http:
          path: users/create
          method: get

and ran something like a manual git bisect changing serverless versions. Works in 2.11.1, 2.13.0, 2.15.0 Doesn't work in 2.21.1, 2.16.1, 2.16.0 So broke in 2.16.0

[pgrzesik]

Thanks @terrybondy, I've observed similar issues locally while trying to reproduce. As it seems to be a separate issue with java support for invoke local, could you please create a corresponding issue in https://github.com/serverless/serverless/issues ?

Note: There's also another bug reported related to invoke local with java: https://github.com/serverless/serverless/issues/4415

@pgrzesik I think this PR should fix the frameworkVersion issue #747
