jabba

Java Version Manager inspired by nvm (Node.js). You might have come across similar beauty in Go (gvm) or Ruby (rvm).

Tested ^{at this point very lightly} on Mac OS X and Linux. Windows support is coming in #1.

Installation

curl -o- https://github.com/shyiko/jabba/raw/master/install.sh | bash && . ~/.jabba/jabba.sh

Installer creates ~/.jabba and adds initialization code to ~/.bashrc (and ~/.bash_profile, ~/.zshrc, ~/.profile) (provided they exist).

Usage

# install particular version of jdk
jabba install 1.8 # "jabba use 1.8" will be called automatically  

# list all installed jdk's
jabba ls

# switch to a different version of jdk
jabba use 1.6.65

# list available jdk's
jabba ls-remote

For more information see jabba --help.
