@autorest/azure-functions-java

Azyre Functions Java Autorest plugin.

This is the AutoRest Java generator for Azure Functions. It's built on AutoRest v3, written in Java, and supports OpenAPI3. It generates Azure Functions apps.

Prerequisites

You need to have the following installed on your machine:

• Node.JS v10.x - v13.x
• Java 8+
• Maven 3.x

You need to have autorest-beta installed through NPM:

npm i -g @autorest/autorest

Usage

Clone this repo and checkout to v4 branch. Make sure all prerequisites are met, and run

mvn package -Dlocal

This will build a file javagen-jar-with-dependencies.jar under javagen module, a preprocess-jar-with-dependencies.jar under preprocessor module. And then run AutoRest

autorest --azure-functions-java
    --use:where/this/repo/is/cloned/autorest.azure-functions-java
    --input-file:path/to/specs.json
    --output-folder:where/to/generate/java/files
    --namespace:specified.java.package

Java files will be generated under where/to/generate/java/files/src/main/java/specified/java/package.

To debug, add --java.debugger to the argument list. The JVM will suspend at the beginning of the execution. Then attach a remote debugger in your IDE to localhost:5005. Make sure you detach the debugger before killing the AutoRest process. Otherwise it will fail to shutdown the JVM and leave it orphaned. (which can be killed in the Task Manager)

Project structure

extension-base

This contains the base classes and utilities for creating an AutoRest extension in Java. It handles the JSON RPC communications with AutoRest core, provides JSON and YAML parsers, and provides the POJO models for the code model output from modelerfour.

Extend from NewPlugin.java class if you are writing a new extension in Java.

javagen

This contains the actually generator extension, including mappers that maps a code model to a Java server models, and templates that writes the Azure Fucntions Java client models into .java files.

tests

This contains the generated classes from the test swaggers in src/main. The code here should always be kept up-to-date with the output of the generator in javagen.

This also contains test code for these generated code under src/test. Running the tests will hit the test server running locally (see https://github.com/Azure/autorest.testserver for instructions) and verify the correctness of the generated code.

Autorest plugin configuration

• Please don't edit this section unless you're re-configuring how the powershell extension plugs in to AutoRest AutoRest needs the below config to pick this up as a plug-in - see AutoRest-extension.md for more information on extension model.
