export_path

Running the script

You will need to run this script as:

. set-jboss-home.sh arg

or

source set-jboss-home.sh arg

To be able to export the values from the script to the current user environment.
These changes are not permanent but only available for the current user environment.

Expected requirements

Install jboss-as and wildfly-as using brew.

$ brew install jboss-as wildfly-as

It will still work with non brew installation but the script was made with brew in mind

Tips

1. Make the script executable

   $ chmod +x /path/to/set-jboss-home.s

2. Add an alias in your .bashrc or .bash_aliases

   alias set-jboss-home=". /path/to/jboss-home.

3. I.e. running wildfly-as as the default JBOSS environment add the line following to your .bashrc file or other init file

   `set-jboss-home wildly-as > /dev/null 2>&1'
