Apache Ant is a build tool that is used extensively by both the Web Space Server source and the extension environment. You can download the latest version of Ant from http://ant.apache.org. After downloading, uncompress the archive into a folder. You then need to set the ANT_HOME environment variable to add binaries to your PATH.
Choose Start -> Control Panel, and double-click the System icon.
Click the Advanced tab, and then click the Environment Variables button.
Under System Variables, select New to create the ANT_HOME environment variable.
Set the variable name to ANT_HOME and the variable value to apache-install-dir\apache-ant-version and click OK.
For example, the installation directory might be C:\Java\apache-ant-1.7.0.
Select New again to create the ANT_OPTS environment variable.
Set the variable name to ANT_OPTS and the variable value to -Xms256M -Xmx512M and click OK.
Select the PATH environment variable and select Edit.
Add %ANT_HOME%\bin to the end or beginning of the PATH.
Click OK and then click OK again.
To test the setting, type ant at a command prompt and press Return.
In your home folder, open the .bash_profile file in the root directory.
Add the following lines to the file, substituting the directory where you installed Ant:
ANT_HOME=/apache-install-dir/apache-ant-version ANT_OPTS="-Xms256M -Xmx512M" PATH=$PATH:$HOME/bin:$ANT_HOME/bin export ANT_HOME ANT_OPTS PATH
To test the setting, type ant at a command prompt and press Return.
