Apache Ant-1.8.1
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 that 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 that executes various tasks. Each task is run by an
object that implements a particular task interface.
This package is known to build and work properly using an
LFS-SVN-20101029 platform.
Package Information
Apache Ant Dependencies
Required
IcedTea6-1.9.7 or JDK-6 Update 18
Recommended
JUnit-4.8.1
User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/apache-ant
Installation of Apache Ant
If it is not possible to install the recommended JUnit package, install Apache Ant by removing the reference to the
test instructions (note that the tests will not be performed):
sed -i 's;jars,test-jar;jars;' build.xml
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 &&
cp -v /usr/share/junit-4.8.1/junit-4.8.1.jar \
lib/optional/junit.jar
The unit regression tests are performed during the build step below
unless JUnit is not installed.
Now, as the root user:
./build.sh -Ddist.dir=/opt/ant-1.8.1 dist &&
ln -v -sf /etc/ant /opt/ant-1.8.1/etc &&
ln -v -sf ant-1.8.1 /opt/ant
Command Explanations
sed -i 's;jars...: If
the JUnit package is not
installed, the regression tests cannot be performed.
sed ...: These
commands change the configuration directory to /etc/ant to conform with FHS guidelines.
cp -v
/usr/share/junit-4.8.1/4.8.1.jar ...: This command
copies the JUnit jar file into the directory where Apache Ant will
look for it.
./build.sh -Ddist.dir=/opt/ant-1.8.1
dist: This command does everything. It builds,
tests, then installs the package into /opt/ant-1.8.1.
ln -v -sf /etc/ant
/opt/ant-1.8.1/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-1.8.1
/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
Contents
Installed Programs:
ant, antRun, antRun.pl,
complete-ant-cmd.pl, runant.pl, and runant.py
Installed Libraries:
ant.jar, ant-*.jar, xercesImpl.jar, and
xml-apis.jar
Installed Directories:
/etc/ant and /opt/ant-1.8.1
