Introduction to Apache Ant
The Apache Ant package is a
Java-based build tool. In theory,
it is like the make
command, 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-8.2
platform.

Apache Ant Dependencies
Required

Installation of Apache Ant

Note
Several dependent packages have moved since the packaging of
Ant requiring download of the
above extra files. Copy those files into the source tree with the
following commands:
cp -v ../jai-core-1.1.3.jar \
../jai-codec-1.1.3.jar \
../xz-1.0.jar lib &&
unzip -p ../NetRexx-3.06-GA.zip lib/NetRexxC.jar > lib/NetRexxC.jar
Build a limited bootstrap version of Apache Ant using the following command:
./bootstrap.sh
Download the rest of the runtime dependencies using the
fetch.xml ant build script:
bootstrap/bin/ant -f fetch.xml -Ddest=system || true &&
cp -v lib/*.jar lib/optional/
Build Apache Ant by running the
following command:
./build.sh -Ddist.dir=$PWD/ant-1.10.2 dist
Install, as the root user:
cp -rv ant-1.10.2 /opt/ &&
chown -R root:root /opt/ant-1.10.2 &&
ln -sfv ant-1.10.2 /opt/ant
Command Explanations
bootstrap/bin/ant -f fetch.xml
-Ddest=system || true: These commands download the
rest of the missing dependencies into the source tree (in the
lib/ directory).
cp -v ...
lib/optional: This command copies the previously
downloaded jar files to the expected place in the source tree so
that ant picks them
up at buld time.
./build.sh -Ddist.dir=$PWD/ant-1.10.2
dist: This command builds, tests, then installs the
package into a temporary directory..
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 issuing, as the
root user:
cat > /etc/profile.d/ant.sh << EOF
# Begin /etc/profile.d/ant.sh
pathappend /opt/ant/bin
export ANT_HOME=/opt/ant
# End /etc/profile.d/ant.sh
EOF
The above instrutions assume you have configured your system as
described in The Bash Shell Startup
Files.
