sample-apps/blank-java - run with maven

[rezadehganpour]

Hi there;
I would like to know how can I run blank-java application with maven since all the scripts that are provided are leveraging gradle.

Thanks

The blank-java project is provided with both, Maven and Gradle. And it can be seen from the template.yml for Gradle and template-mvn.yml for Maven.
If you want to build the project locally using Maven, run the following command :

$ mvn clean package

it will build the project and then package it in a jar containig all dependencies under the target/ folder.
You can then use the generated jar to update the AWS Lambda function.

To do this, open your Lambda Function in the console and then update the jar.

Follow this link for more information about AWS Lambda deployment package in Java.

I mean, sure, but the description in the README says that you need either Gradle or Maven, yet the instructions then only work if you have Gradle.

I see that some of the other examples (e.g. java-events) do have code in their 1/2/3... scripts that looks like they’re meant to work with Maven. But none of them have a “build-layer” command, and it’s not obvious how to do that with Maven.
