Apache Ant-1.7.0
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.
Package Information
Apache Ant Dependencies
Required
JDK-6 Update
5 and JUnit-4.3.1
User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/apache-ant
Installation of Apache Ant
Install Apache Ant by running the
following commands:
sed -i 's|${dist.dir}/etc|/etc/ant|' build.xml
sed -i 's|/etc/ant.conf|/etc/ant/ant.conf|' src/script/ant
The unit regression tests are performed in the build step below.
Now, as the root
user:
./build.sh -Ddist.dir=/opt/ant-1.7.0 dist &&
ln -v -sf /etc/ant /opt/ant-1.7.0/etc &&
ln -v -sf ant-1.7.0 /opt/ant
Command Explanations
sed ...: These
commands change the configuration directory to /etc/ant
to conform with FHS guidelines.
./build.sh -Ddist.dir=/opt/ant-1.7.0
dist: This command does everything. It builds,
tests, then installs the package into /opt/ant-1.7.0
.
ln -v -sf /etc/ant
/opt/ant-1.7.0/etc: The sed commands change the
configuration directory to /etc/ant
and this command creates a symlink from the configuration directory
back to the installation directory as the package is expecting to
find some files there.
ln -v -sf ant-1.7.0
/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
