setting up environment variables in windows 7 for java and ant

问题

I have a book that says to do the following.

Add a JAVA_HOME and ANT_HOME environment variable. - check
Add $JAVA_HOME/bin and $ANT_HOME/bin to my path variable - check

When I then go to the command prompt and try ant -version it says ant is not a recognized command. If I then take the value I plugged into the ANT_HOME variable and use it in place of $ANT_HOME it all works. Is this the way it's supposed to work in windows? I'm not sure so I just figured that whatever was put in ANT_HOME was then parsed in the path variable when used as $ANT_HOME. Thanks.

you can try the following:

SET ANT_HOME=my_path_to_ant_folder
SET JAVA_HOME=my_path_to_jdk_folder
SET PATH=%PATH%;%ANT_HOME%/bin;%JAVA_HOME%\bin;

right click My Computer
click Properties
go to Advanced system settings
click on Advanced tab
click on Environment Variables
click on New...

Now you can define an environment variable, type JAVA_HOME in Variable name and in Variable value the path to you JAVA_HOME, the same thing goes for ANT_HOME.

$ANT_HOME doesn't mean $ANT_HOME, literally. $ANT_HOME means "the value of ANT_HOME".

If Ant is installed at c:\ant, your environment variables should be:

ANT_HOME=c:\ant
PATH = ...;c:\ant\bin;...

Same for JAVA_HOME.
