Recently I have been trying to make changes so I can do builds through Ant and the command line. This has forced me to reconfigure my setup. In order to make java available on the class path I typed the following in the command propmt…

set JAVA_HOME=C:\Java\JDK 1.6.0_08

that being the directory of my java installation. Then I will set my ANT_HOME variable to
the following

set ANT_HOME=C:\Ant

I can check both of these following doing this by doing

javac

and 

ant

on the command line and getting the usual output signifying that they are being read.Following this I will set them both on the 

path

by doing the following

set PATH=%PATH%;%JAVA_HOME%\bin;%ANT_HOME%\bin

After doing this I check the command line for each of them and they will work fine.

The problem that I am having is that randomly, I will go back and do the same command, and it will tell me that 

"ant" is not recognized as an internal or external command...

I know this is the message you get when you type an incorrect command. Why is is that every website, tutorial and book I look at for configuring these services tells me to do the same process and none of them are working? Am I completely missing something?

    If you’re on Windows remember that any changes that are made in a command window only endure until the window is closed.

    Go to My Computer --> Properties --> Advanced --> Environment Variables and configure your variables here instead.

    After that, close your command line window and open it again… Windows should now be able to recognize your commands.

    Regards.
