Jakarta Ant
As you work with Java, you’ll often encounter references to Ant, an open source tool for managing build processes and other tasks. Ant is a great companion tool to IDEs and text editors, as it can manage complex build tasks, compilation, and even those nasty classpath issues discussed earlier. This section will describe Ant in some detail.
Ant is part of Apache’s Jakarta project. Originally
created to provide a cross-platform, portable replacement for the
Unix make command, it has become a powerful
development, deployment, and installation tool. To use Ant, run
scripts from the command line, passing in an XML build file. Inside
the build file, you can define variables and tasks to be performed at
build time.
Installation and Setup
You can download Ant from http://ant.apache.org/. The latest version
as of this writing is 1.5.1, and you can select a ZIP file or a
gzipped version. I downloaded
jakarta-ant-1.5.1-bin.tar.gz. Expand the file to
jakarta-ant-1.5.1 and copy the resultant
directory somewhere easily accessible (I used
~/dev for a user-specific installation). Then
put the bin subdirectory in your path:
[Wills-Laptop:~] wiverson% setenv PATH ~/dev/jakarta-ant-1.5.1/bin:$PATH
To run Ant, use the ant script
(ant.bat on Windows, and just plain ant on Unix-based systems such as Mac OS X):
[Wills-Laptop:~] wiverson% ant Buildfile: build.xml does not exist! Build failed
As the message here indicates, Ant expects a build file, generally called build.xml, to give it instructions. ...
