Apache Ant-1.6.2

Introduction to Apache Ant

The Apache Ant package is a Java-based build tool. In theory, it is kind of like make, but without make's wrinkles. Ant is different. Instead of a model where it is extended with shell-based commands, Ant is extended using Java classes. Instead of writing shell commands, the configuration files are XML-based, calling out a target tree where various tasks get executed. Each task is run by an object that implements a particular task interface.

Apache Ant dependencies



Installation of Apache Ant

Note: you may need additional libraries to satisify the build requirements of various packages installed using Apache Ant. Review the table at http://ant.apache.org/manual/install.html#librarydependencies for any prerequisite libraries you may need. One such library is the JUnit testing framework library. Many Ant-installed packages will use this library to perform the unit tests during the build process. To install the JUnit library along with the Apache Ant package, download it from http://www.junit.org/, unzip the distribution file (requires UnZip-5.51) and copy the junit.jar file into the lib subdirectory of the Apache Ant source tree before beginning the Apache Ant build.

Install Apache Ant by running the following commands:

patch -Np1 -i ../apache-ant-1.6.2-blfs_install-1.patch

Now, as the root user:

./build.sh -Ddist.dir=/opt/ant-1.6.2 dist &&
ln -sf /etc/ant /opt/ant-1.6.2/etc &&
ln -sf ant-1.6.2 /opt/ant

Command explanations

./build.sh -Ddist.dir=/opt/ant-1.6.2 dist: This command does everything. It builds the package, then installs the package into /opt/ant-1.6.2.

ln -sf /etc/ant /opt/ant-1.6.2/etc: The patch changes the configuration directory to /etc/ant to conform with FHS guidelines. This command creates a symlink from the configuration directory back to the installation directory as the package is expecting to find the files there.

ln -sf ant-1.6.2 /opt/ant: This command is optional, and creates a convenience symlink.

Configuring Apache Ant

Config files

/etc/ant/ant.conf, ~/.ant/ant.conf and ~/.antrc

Configuration Information

Some packages will require ant to be in the search path and the $ANT_HOME environment variable defined. Satisfy these requirements by adding the following lines to /etc/profile or to individual user's ~/.profile or ~/.bashrc files:

export PATH=$PATH:/opt/ant/bin
export ANT_HOME=/opt/ant


Installed Programs: ant, antRun, antRun.pl, complete-ant-cmd.pl, runant.pl and runant.py
Installed Libraries: ant-*.jar, xercesImpl.jar and xml-apis.jar
Installed Directories: /etc/ant and /opt/ant-1.6.2
