Install javm

javm provides install scripts for Linux, macOS, and Windows, plus simple shell setup steps.

Quick install

Linux & macOS

Install the latest version for your system by running the following command:

curl -fsSL https://javm.dev/install.sh | bash

Install a specific version or channel:

# latest nightly build
curl -fsSL https://javm.dev/install.sh | bash -s nightly

# specific release
curl -fsSL https://javm.dev/install.sh | bash -s v0.1.0

Windows

Install the latest version for your system by running the following command:

irm https://javm.dev/install.ps1 | iex

Install a specific version or channel:

# nightly
iex "& {'{'} $(irm https://javm.dev/install.ps1) {'}'} nightly"

# specific release
iex "& {'{'} $(irm https://javm.dev/install.ps1) {'}'} v0.1.0"

note

The scripts auto-detect your platform/architecture and support three modes: latest (default), nightly, or an explicit tag like v0.1.0.

Shell setup

Enable javm in your shell by evaluating the output of javm init <shell> and adding it to your profile.

Bash

Add to ~/.bashrc (or ~/.zshrc if you use Zsh with Bash config):

eval "$(javm init bash)"

Zsh

Add to ~/.zshrc:

eval "$(javm init zsh)"

Fish

Add to ~/.config/fish/config.fish:

javm init fish | source

Nushell

Generate the script file using javm init nu:

javm init nu | save -f ~/.local/share/javm/javm.nu

Add this to your config.nu (you can find it by running $nu.config-path):

source ~/.local/share/javm/javm.nu

PowerShell

Add to your profile:

iex "$(javm init pwsh)"

tip

To find your PowerShell profile path run:

echo $PROFILE

After editing your profile, restart the shell (or reload your profile) to apply changes.

Advanced: Static Shell Integration (Audit & Performance)

Unlike tools that require opaque shims, javm generates a clear, readable shell function. You can eval it for convenience, or verify and paste it directly into your profile for maximum security and startup speed.

If you prefer to avoid dynamic evaluation on every shell startup, you can append the static integration code directly to your profile:

Bash

javm init bash >> ~/.bashrc

Zsh

javm init zsh >> ~/.zshrc

Fish

javm init fish >> ~/.config/fish/config.fish

PowerShell

javm init pwsh >> $PROFILE

This way, the integration code remains static and audit-ready in your configuration file.

warning

If you update javm in the future, you might need to update this static code if the shell integration logic changes.
