Building Quarkus apps with Quarkus Command Line Interface (CLI)

The quarkus command lets you create projects, manage extensions and do essential build and dev commands using the underlying project build tool.

Installing the CLI

The Quarkus CLI is available in several developer-oriented package managers such as:

If you already use (or want to use) one of these tools, it is the simplest way to install the Quarkus CLI and keep it updated.

In addition to these package managers, the Quarkus CLI is also installable via JBang. Choose the alternative that is the most practical for you:

  • JBang - for Linux, macOS and Windows

  • SDKMAN! - for Linux and macOS

  • Homebrew - for Linux and macOS

  • Chocolatey - for Windows

  • Scoop - for Windows

JBang

The Quarkus CLI is available as a jar installable using JBang.

JBang will use your existing Java or install one for you if needed.

On Linux, macOS, and Windows (using WSL or bash compatible shell like Cygwin or MinGW)

curl -Ls https://sh.jbang.dev | bash -s - trust add https://repo1.maven.org/maven2/io/quarkus/quarkus-cli/
curl -Ls https://sh.jbang.dev | bash -s - app install --fresh --force quarkus@quarkusio

On Windows using Powershell:

iex "& { $(iwr https://ps.jbang.dev) } trust add https://repo1.maven.org/maven2/io/quarkus/quarkus-cli/"
iex "& { $(iwr https://ps.jbang.dev) } app install --fresh --force quarkus@quarkusio"

If JBang has already been installed, you can directly use it:

# This can also be used to update to the latest version
jbang app install --fresh --force quarkus@quarkusio

If you want to use a specific version, you can directly target a version:

# Create an alias in order to use a specific version
jbang app install --name qs2.2.5 io.quarkus:quarkus-cli:2.2.5.Final:runner

If you have built Quarkus locally, you can use that version:

# Use the latest (or locally built) snapshot (with qss as an alias)
jbang app install --force --name qss ~/.m2/repository/io/quarkus/quarkus-cli/999-SNAPSHOT/quarkus-cli-999-SNAPSHOT-runner.jar

Once installed quarkus will be in your $PATH and if you run quarkus --version it will print the installed version:

quarkus --version
{quarkus-version}
Caution
Use a recent JBang version

If you get an error about app not being readable then you probably have a JBang version older than v0.56.0 installed. Please remove or upgrade it to a recent version.

If you are installing JBang for the first time, start a new session to update your PATH.
Caution
Dependency required on RHEL 9.x

In order to install JBang, you need to install the tar command on your system.

dnf install tar
SDKMAN!

SDKMAN! can be used to manage development environments. It can manage parallel versions of multiple Software Development Kits on most Unix based systems, making it a very good alternative to keep multiple JDK versions handy.

With SDKMAN!, you can also install popular Java tools, including the Quarkus CLI.

Note

Make sure you have a JDK installed before installing the Quarkus CLI.

To list the available versions of Java, use sdk list java. You can then install the version of OpenJDK you want with sdk install java x.y.z-open (or the JDK of another vendor if it is your preference).

To install the Quarkus CLI using SDKMAN!, run the following command:

sdk install quarkus

It will install the latest version of the Quarkus CLI.

Once installed quarkus will be in your $PATH and if you run quarkus --version it will print the installed version:

quarkus --version
{quarkus-version}

SDKMAN! will let you know when new versions are available so updates will be straightforward:

sdk upgrade quarkus
Homebrew

Homebrew is a package manager for macOS (and Linux).

You can use Homebrew to install (and update) the Quarkus CLI.

Note

Make sure you have a JDK installed before installing the Quarkus CLI. We haven’t added an explicit dependency as we wanted to make sure you could use your preferred JDK version.

You can install a JDK with brew install openjdk for the latest Java version, brew install openjdk@17 for Java 17, or brew install openjdk@11 for Java 11.

To install the Quarkus CLI using Homebrew, run the following command:

brew install quarkusio/tap/quarkus

It will install the latest version of the Quarkus CLI. This command can also be used to update the Quarkus CLI.

Once installed quarkus will be in your $PATH and if you run quarkus --version it will print the installed version:

quarkus --version
{quarkus-version}

You can upgrade the Quarkus CLI with:

brew update (1)
brew upgrade quarkus (2)

  1. Update all package definitions and Homebrew itself

  2. Upgrade Quarkus CLI to the latest version

Chocolatey

Chocolatey is a package manager for Windows.

You can use Chocolatey to install (and update) the Quarkus CLI.

Note

Make sure you have a JDK installed before installing the Quarkus CLI.

You can install a JDK with choco install ojdkbuild17 for Java 17 or choco install ojdkbuild11 for Java 11.

To install the Quarkus CLI using Chocolatey, run the following command:

choco install quarkus

It will install the latest version of the Quarkus CLI.

Once installed quarkus will be in your $PATH and if you run quarkus --version it will print the installed version:

quarkus --version
{quarkus-version}

You can upgrade the Quarkus CLI with:

choco upgrade quarkus
Scoop

Scoop is a package manager for Windows. You can use Scoop to install (and update) the Quarkus CLI.

Note

Make sure you have a JDK installed before installing the Quarkus CLI. You can install a JDK with scoop install openjdk17 for Java 17 or scoop install openjdk11 for Java 11.

To install the Quarkus CLI using Scoop, run the following command:

scoop install quarkus-cli

It will install the latest version of the Quarkus CLI. Once installed quarkus will be in your $PATH and if you run quarkus --version it will print the installed version:

quarkus --version
{quarkus-version}

You can upgrade the Quarkus CLI with:

scoop update quarkus-cli

Tip

While this document is a useful reference, the client help is the definitive source.

If you don’t see the output you expect, use --help to verify that you are invoking the command with the right arguments.

Creating a new project

To create a new project we use the create command (the app subcommand is implied when not specified):

quarkus create
-----------

applying codestarts...
📚  java
🔨  maven
📦  quarkus
📝  config-properties
🔧  dockerfiles
🔧  maven-wrapper
🚀  resteasy-codestart

-----------
[SUCCESS] ✅ quarkus project has been successfully generated in:
--> /<output-dir>/code-with-quarkus

This will create a folder called 'code-with-quarkus' in your current working directory using default groupId, artifactId and version values (groupId='org.acme', artifactId='code-with-quarkus' and version='1.0.0-SNAPSHOT').

Note: the emoji shown above may not match precisely. The appearance of emoji can vary by font, and terminal/environment. IntelliJ IDEA, for example, has several long-running issues open regarding the behavior/rendering of emoji in the terminal.

As of 2.0.2.Final, you should specify the groupId, artifactId and version using group:artifactId:version coordinate syntax directly on the command line. You can selectively omit segments to use default values:

# Create a project with groupId=org.acme, artifactId=bar, and version=1.0.0-SNAPSHOT
quarkus create app bar

# Create a project with groupId=com.foo, artifactId=bar, and version=1.0.0-SNAPSHOT
quarkus create app com.foo:bar

# Create a project with groupId=com.foo, artifactId=bar, and version=1.0
quarkus create app com.foo:bar:1.0

The output will show your project being created:

-----------

applying codestarts...
📚  java
🔨  maven
📦  quarkus
📝  config-properties
🔧  dockerfiles
🔧  maven-wrapper
🚀  resteasy-codestart

-----------
[SUCCESS] ✅ quarkus project has been successfully generated in:
--> /<output-dir>/bar
-----------

Use the help option to display options for creating projects:

quarkus create app --help
quarkus create cli --help
Warning

Previous versions of the CLI used options --group-id (-g),--artifact-id (-a) and --version (-v) to specify the groupId, artifactId, and version. If the output isn’t what you expect, double-check your client version quarkus version and help quarkus create app --help.

Specifying the Quarkus version

Both quarkus create and quarkus extension list allow you to explicitly specify a version of Quarkus in one of two ways:

  1. Specify a specific Platform Release BOM

    A Quarkus Platform release BOM is identified by groupId:artifactId:version (GAV) coordinates. When specifying a platform release BOM, you may use empty segments to fall back to default values (shown with quarkus create app --help). If you specify only one segment (no :), it is assumed to be a version.

    For example:

    • With the 2.0.0.Final version of the CLI, specifying -P :quarkus-bom: is equivalent to -P io.quarkus:quarkus-bom:2.0.0.Final. Specifying -P 999-SNAPSHOT is equivalent to -P io.quarkus:quarkus-bom:999-SNAPSHOT.

    • With the 2.1.0.Final version of the CLI, io.quarkus.platform is the default group id. Specifying -P :quarkus-bom: is equivalent to -P io.quarkus.platform:quarkus-bom:2.1.0.Final. Note that you need to specify the group id to work with a snapshot, e.g. -P io.quarkus::999-SNAPSHOT is equivalent to -P io.quarkus:quarkus-bom:999-SNAPSHOT.

      Note: default values are subject to change. Using the --dry-run option will show you the computed value.

  2. Specify a Platform Stream

    A platform stream operates against a remote registry. Each registry defines one or more platform streams, and each stream defines one or more platform release BOM files that define how projects using that stream should be configured.

    Streams are identified using platformKey:streamId syntax. A specific stream can be specified using -S platformKey:streamId. When specifying a stream, empty segments will be replaced with discovered defaults, based on stream resource resolution rules.

Working with extensions

quarkus ext --help

Listing extensions

The Quarkus CLI can be used to list Quarkus extensions.

quarkus ext ls

The format of the result can be controlled with one of four options:

  • --name Display the name (artifactId) only

  • --concise Display the name (artifactId) and description

  • --full Display concise format and version/status-related columns.

  • --origins Display concise information along with the Quarkus platform release origin of the extension.

The behavior of quarkus ext ls will vary depending on context.

Listing Extensions for a Quarkus release

If you invoke the Quarkus CLI from outside of a project, Quarkus will list all the extensions available for the Quarkus release used by the CLI itself.

You can also list extensions for a specific release of Quarkus using -P or -S, as described in Specifying the Quarkus version.

This mode uses the --origins format by default.

Listing Extensions for a Quarkus project

When working with a Quarkus project, the CLI will list the extensions the current project has installed, using the --name format by default.

Use the --installable or -i option to list extensions that can be installed from the Quarkus platform the project is using.

You can narrow or filter the list using search (--search or -s).

quarkus ext list --concise -i -s jdbc
JDBC Driver - DB2                                  quarkus-jdbc-db2
JDBC Driver - PostgreSQL                           quarkus-jdbc-postgresql
JDBC Driver - H2                                   quarkus-jdbc-h2
JDBC Driver - MariaDB                              quarkus-jdbc-mariadb

JDBC Driver - MySQL                                quarkus-jdbc-mysql
JDBC Driver - Oracle                               quarkus-jdbc-oracle
JDBC Driver - Derby                                quarkus-jdbc-derby
Elytron Security JDBC                              quarkus-elytron-security-jdbc
Agroal - Database connection pool                  quarkus-agroal

Adding extension(s)

The Quarkus CLI can add Quarkus one or more extensions to your project with the 'add' command:

quarkus ext add kubernetes health
[SUCCESS] ✅ Extension io.quarkus:quarkus-kubernetes has been installed
[SUCCESS] ✅ Extension io.quarkus:quarkus-smallrye-health has been installed

Removing extension(s)

The Quarkus CLI can remove one or more extensions from your project with the 'remove' command:

quarkus ext rm kubernetes
[SUCCESS] ✅ Extension io.quarkus:quarkus-kubernetes has been uninstalled

Build your project

To build your project using the Quarkus CLI (using the default configuration in this example):

quarkus build

Warning
Compatibility with Quarkus 1.x

The version 2 Quarkus CLI can not be used with 1.x Quarkus projects or releases. Use the Maven/Gradle plugins when working with Quarkus 1.x projects.

Shell autocomplete and aliases

Automatic command completion is available for Bash and Zsh:

# Setup autocompletion in the current shell
source <(quarkus completion)

If you choose to use an alias for the quarkus command, adjust command completion with the following commands:

# Add an alias for the quarkus command
alias q=quarkus
# Add q to list of commands included in quarkus autocompletion
complete -F _complete_quarkus q

Container images

The Quarkus CLI allows building container images without tampering with your project configuration (adding / removing container image extensions). To build the image for your project:

quarkus image build

The image build command can be used directly, or a subcommand can be selected. The available subcommands are:

  • docker

  • buildpacks

  • jib

  • openshift

Each subcommand corresponds to an image building tool supported by Quarkus and gives access to specific configuration options.

For example, to use a Cloud Native Buildpack with a custom builder image, use the following:

quarkus image build buildpack --builder-image <your builder image>

Pushing

The image push command is similar to image build, and surfaces some basic options required to push images to a target container registry.

quarkus image push --registry=<image registry> --registry-username=<registry username> --registry-password-stdin
