Features

Here is a list of some of the coolest features of the plugin:

• ✅ Generation of Quarkus applications/libraries based on Quarkus app generator API

• ✅ Building, packaging, testing, etc your Quarkus projects

• ✅ 🆕 Built-in support for creating multi-modules Quarkus projects with both Maven and Gradle

• ✅ Built-in support for code formatting using the excellent Spotless plugin for Maven or Gradle

• ✅ Built-in support for corporate proxies (either via --proxyUrl or by defining environment variable http_proxy, HTTP_PROXY, https_proxy or HTTPS_PROXY)

• ✅ Integration with Nx's dependency graph (through nx graph or nx affected:graph): this allows you to visualize the dependencies of any Quarkus's Maven/Gradle applications or libraries inside your workspace, just like Nx natively does it for JS/TS-based projects! Example of running the nx graph command on a workspace with 2 Quarkus projects inside

• ...

Setup

You can now use our own create-nx-quarkus CLI to easily create a Nx workspace, that comes with this plugin pre-installed!

Simply run:

# npm
npx create-nx-quarkus@latest
# or
# yarn
yarn create nx-quarkus

and you are good to go‧o‧o‧o! 🚀

More information here: create-nx-quarkus

Otherwise, this is the traditional way of setting things up:

1. Creating the Nx workspace

If you have not already, create an Nx workspace with the following:

# npm
npx create-nx-workspace@latest

# yarn
yarn create nx-workspace

2. Installing the Plugin

Then you need to install the plugin in order to generate Quarkus applications later on.

# npm
npm install @nxrocks/nx-quarkus --save-dev

# yarn
yarn add @nxrocks/nx-quarkus --dev

Generators

This plugin is composed of 2 main generators:

• project generator
• link generator

Generating Project (project generator)

Simply run the project generator with the following command:

nx g @nxrocks/nx-quarkus:project <your-app-name>

you can also use the following aliases to call the generator: proj, new, or create

You will be prompted for entering the most commonly customized generation options (like project's groupId, artifactId, packaging, dependencies, etc).

To skip the interactive prompt, or if you want to customize all non-prompted options, you can pass them along directly when running the command, as such:

nx g @nxrocks/nx-quarkus:project <your-app-name> --optionName1 optionValue1 ... --optionNameN optionValueN

Generation Options

Here the list of available generation options :

| Arguments | Description | | --------- | ------------------------- | | <name> | The name of your project. |

| Option | Value | Description | | --------------------------- | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | projectType | application | library | Type of project to generate | | buildSystem | MAVEN | GRADLE | Build system | | groupId | string | GroupId of the project | | artifactId | string | ArtifactId of the project | | skipFormat | boolean | Do not add the ability to format code (using Spotless plugin) | | extensions | string | List of extensions to use (comma-separated). Go to recipes for more information | | transformIntoMultiModule | boolean | Transform the project into a multi-module project. Go to recipes for more information | | addToExistingParentModule | boolean | Add the project into an existing parent module project. Go to recipes for more information | | parentModuleName | string | Name of the parent module to create or to add child project into. Go to recipes for more information | | keepProjectLevelWrapper | boolean | Keep the Maven or Gradle wrapper files from child project (when generating a multi-module project). Go to recipes for more information | | quarkusInitializerUrl | https://code.quarkus.io | URL to the Quarkus Initializer instance to use | | proxyUrl | | The URL of the (corporate) proxy server to use to access Quarkus Initializer | | skipeCodeSamples | string | Whether or not to include code samples from extensions (when available) | | tags | string | Tags to use for linting (comma-separated) | | directory | string | Directory where the project is placed | | javaVersion | string \| number | The java version of the project (currently supports versions 17 and 21) |

Note: If you are working behind a corporate proxy, you can use the proxyUrl option to specify the URL of that corporate proxy server. Otherwise, you'll get a ETIMEDOUT error when trying to access official Quarkus Initializer to generate the project. Even simpler, you can just define environment variable http_proxy, HTTP_PROXY, https_proxy or HTTPS_PROXY globally.

Linking Projects (link generator)

This generator is used to link a Quarkus project inside the workspace (the source project) with another project (the _target project), by adding the source project as an implicit dependency of the later.

Simply run the link generator with the following command:

nx g @nxrocks/nx-quarkus:link

you can also use the following aliases to call the generator: link-project

You will be prompted for entering the most commonly customized generation options (sourceProjectName, targetProjectName).

To skip the interactive prompt, you can pass options along directly when running the command, as such:

nx g @nxrocks/nx-quarkus:link --sourceProjectName <your-quarkus-app> --targetProjectName <your-other-app>

or even simpler:

nx g @nxrocks/nx-quarkus:link  <your-quarkus-app>  <your-other-app>

Generation Options

Here the list of available generation options :

| Arguments | Description | | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | | <sourceProjectName> | The name of the source(Quarkus) project to link from. 1st argument of the link generator. Can also be provided as option --sourceProjectName | | <targetProjectName> | The name of the target project to link to. 2nd argument of the link generator. Can also be provided as option --targetProjectName |

Executors

Once your app is generated, you can now use executors to manage it.

Here the list of available executors:

| Executor | Arguments | Description | | ------------------------- | ------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | | run | dev | serve | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Runs the project in dev mode using either ./mvnw\|mvn quarkus:dev or ./gradlew\|gradle quarkusDev | | remote-dev | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Runs the project in remote dev mode using either ./mvnw\|mvn quarkus:remote-dev or ./gradlew\|gradle quarkusRemoteDev | | build | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Builds a native or container friendly image either ./mvnw\|mvn build or ./gradlew\|gradle build | | test | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Tests the project using either ./mvnw\|mvn test or ./gradlew\|gradle test | | clean | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Cleans the project using either ./mvnw\|mvn clean or ./gradlew\|gradle clean | | format | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Format the project using Spotless plugin for Maven or Gradle | | package | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Packages the project using either ./mvnw\|mvn package or ./gradlew\|gradle package | | install | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Installs the project's artifacts to local Maven repository (in ~/.m2/repository) using either ./mvnw\|mvn install or ./gradlew\|gradle publishToMavenLocal | | add-extension | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Adds a new extension to the project using either ./mvnw\|mvn quarkus:add-extension or ./gradlew\|gradle quarkusAddExtension | | list-extensions | ignoreWrapper:boolean, runFromParentModule:boolean, args: string[] | Adds a new extension to the project using either ./mvnw\|mvn quarkus:list-extensions or ./gradlew\|gradle quarkusListExtensions |

In order to execute the requested command, each executor will use, by default, the embedded ./mvnw or ./gradlew executable, that was generated alongside the project. If you want to rely on a globally installed mvn or gradle executable instead, add the --ignoreWrapper option to bypass it. This can be useful in a CI environment for example, or in a restricted environment where the binary cannot be downloaded (due to proxy/firewall limitations).

You can pass in additional arguments to the underlying Gradle or Maven, either temporarily (via --args="..."). For example:

nx remote-dev your-quarkus-app --args="-Dquarkus.live-reload.url=http://my-remote-host:8080"

Or, permanently by editing the related executor in the workspace.json file, as such:

{
  "version": 1,
  "projects": {
    "your-quarkus-app": {
      "projectType": "application",
      "root": "apps/your-quarkus-app",
      "sourceRoot": "apps/your-quarkus-app/src",
      "targets": {
        "remote-dev": {
          "executor": "@nxrocks/nx-quarkus:remote-dev",
          "options": {
            "root": "apps/your-quarkus-app",
            "args": ["-Dquarkus.live-reload.url=http://my-remote-host:8080"]// your additional args here
          }
        }
      }
    }},
  "cli": {
    "defaultCollection": "@nx/workspace"
  }
}

Running the project in dev mote - (dev or serve Executors)

nx serve your-quarkus-app

// or

nx dev your-quarkus-app

Install the project's artifacts to local Maven repository (in ~/.m2/repository) - (install Executor)

nx install your-quarkus-app

Running the project in remote dev mode - (remote-dev Executor)

// for a maven-based project
nx remote-dev your-quarkus-app --args="-Dquarkus.live-reload.url=http://my-remote-host:8080"

// for a gradle-based project
nx remote-dev your-quarkus-app --args="-Dquarkus.live-reload.url=http://my-remote-host:8080"

Building the aplication - (build Executor)

nx build your-quarkus-app

Note: a task dependency to install executor of dependent (library) projects is added by the plugin, so that Nx will automatically install dependent artifacts to your local Maven repository, prior to running this command. This is particulaly useful, when for example, you have a Spring Boot application that depends on another Spring boot library in the workspace. No more need to install the library yourself first!

Testing the project - (test Executor)

nx test your-quarkus-app

Cleaning the project - (clean Executor)

nx clean your-quarkus-app

Formatting the project - (format Executor)

nx run your-quarkus-app:format

// or its simpler alias

nx apply-format your-quarkus-app

Note: You *cannot** use the shorter nx format your-boot-app syntax here, because that would conflict with the native format command from Nx CLI.

Packaging the project - (package Executor)

nx package your-quarkus-app

Add Extension the project - (add-extension Executor)

// for a maven-based project
nx add-extension your-quarkus-app --args="-Dextensions=resteasy,hibernate-validator"

// for a gradle-based project
nx add-extension your-quarkus-app --args="--extensions=resteasy,hibernate-validator"

List Extensions in the project - (list-extensions Executor)

nx list-extensions your-quarkus-app
