[Feedback] amplify mock step fails if Java JDK is not installed

See original GitHub issue

Page: /start/q/integration/react

Feedback:

The command amplify mock api on the page https://docs.amplify.aws/start/getting-started/data-model/q/integration/react#optional-test-your-api results in an error if the correct Java JDK is not installed.

 ~ amplify mock api  
Failed to start API Mock endpoint Error: max retries hit for starting dynamodb emulator

In my case, this fix worked: https://github.com/aws-amplify/amplify-cli/issues/2062#issuecomment-533700476.

It might make sense to add a note regarding the Java JDK dependency for this step.

Hi @janaka

Yes Installing JRE will work fine. Here we are checking for java version >= 8 as it is a requirement for DynamoDB local which we are using to mock api.

Closing this issue as it seems to be solved. If you are still stuck after upgrading java version , feel free to comment and Ill reopen this issue again

I get the following error and pop up. Running amplify-cli v4.26.0

Could find any mention of this dependency in pre-reqs etc. presume I don’t actually need the JDK just the runtime. Would be good to have instructions. Not depending on Java would be even better. Java always feels clunky as a tool dependency.
