Install the Camel CLI Launcher

The Camel CLI Launcher can be installed on a single machine without a package manager. The installer scripts published on this site download the launcher from Maven Central and verify it against a SHA-256 checksum published here before running it. Installation is always per-user and never requires sudo or elevation.

Requirements

  • A Java 17 or newer runtime discoverable on your system.
  • curl (macOS and Linux) or PowerShell 5.1+ (Windows).

Quick install

With no arguments the installer resolves and installs the latest published release.

macOS and Linux

curl -fsSL https://camel.apache.org/install.sh | sh

Windows (PowerShell)

irm https://camel.apache.org/install.ps1 | iex

Install a specific version, or inspect before running

If you prefer not to pipe a script straight into a shell, download it, read it, then run it. The same approach lets you pin an exact X.Y.Z version.

macOS and Linux

curl -fsSL https://camel.apache.org/install.sh -o install.sh
less install.sh
sh install.sh --version 4.21.0

Windows (PowerShell)

irm https://camel.apache.org/install.ps1 -OutFile install.ps1
notepad install.ps1
./install.ps1 -Version 4.21.0

How the security works

The installer downloads the release archive from Maven Central, but verifies it against a SHA-256 checksum recorded in a manifest served from camel.apache.org. The archive and the checksum come from two independent hosts, so tampering would require compromising both at once. The installer also rejects archives containing absolute paths, ../ traversal, escaping symlinks, or more than one top-level directory, and runs the staged launcher once to confirm a Java 17+ runtime before activating it. If that check fails, any previously installed version is left untouched.

The installers are maintained in the Apache Camel repository (apache/camel#24682).
