In order to install Forge, you need to perform the following steps:
Download and unzip Forge from http://forge.jboss.org/ into a folder on your hard disk; this folder will be your
FORGE_HOME.Add
FORGE_HOME/binto your path (Windows, Linux, and Mac OS X).
In Unix-based operating systems, this typically means editing your ~/.bashrc or ~/.profile; you will need to enter the following code snippet:
export FORGE_HOME=~/forge/ export PATH=$PATH:$FORGE_HOME/bin
In Windows systems, you will need to open the Control Panel window, then navigate to System Properties | Advanced | Environment Variables, and add these two entries visually. It is recommended to set user variables for Forge, unless you have placed the unzipped distribution in a folder where all users can access it.
In case of any problem, check out the online installation guide available at http://forge.jboss.org/document/installation.
