Installation

Prebuilt releases are available for Windows, macOS, and Linux on amd64 and arm64.

macOS or Linux

curl -fsSL https://github.com/codeboyzhou/javaup/releases/latest/download/install.sh | sh

The installer detects the platform, verifies the release checksum, installs jup under ~/.javaup/bin, and updates the relevant shell profile.

Windows

Run in PowerShell 5.1 or later:

irm https://github.com/codeboyzhou/javaup/releases/latest/download/install.ps1 | iex

The installer verifies the release checksum, installs jup.exe under %USERPROFILE%\.javaup\bin, and adds that directory to the user PATH. Restart terminals and IDEs that were open during installation so they inherit the new PATH.

Other Installation Methods

Install with the Go version declared in go.mod, or newer:

go install github.com/codeboyzhou/javaup/cmd/jup@latest

Or build from source:

git clone https://github.com/codeboyzhou/javaup.git
cd javaup
go run build.go

The binary is written to dist/jup.exe on Windows or dist/jup on macOS and Linux. Archives, checksums, and installers can also be inspected on GitHub Releases.

`JAVAUP_VERSION`	Install a specific release, such as `v0.3.0`
