Basics of ANT

 Introduction – What & Why
 Installing and Executing ANT
 ANT Terminologies and Concepts
 Core ANT tasks
 Creating a build file
 Execute an executable
 Executing SQL queries
 DEMO
 Queries

 Apache Ant (Ant) is a general purpose build tool. Ant
is an abbreviation for Another Neat Tool.
 Ant is primarily used for building and deploying Java
projects but can be used for every possible repetitive
tasks.
 ANT is Operating System and Language Neutral.
 ANT is implemented in Java.

 Ant can get source code from version control
 CVS, Subversion, Synergy, Perforce, ClearCase and many
more
 Ant can compile source code
 Ant can run unit tests
 JUnit3, JUnit4, TestNG, or any arbitrary test application
 Ant can package compiled code and resources
 jars, wars, ears, tars, zips, whatever

 Download latest stable zip file
from http://ant.apache.org/bindownload.cgi
 Unzip downloaded file into a directory
 Setup Environment Variables
 Define ANT_HOME to be the location where Ant was
unzipped
 Define JAVA_HOME to be the location where the JDK is
installed
 Add %ANT_HOME%bin to the PATH
 Check your installation by opening a command line
and typing ant -version into the commend line.

 Ant Project – a collection of named targets that can
run in any order. Each build file contains one project.
 Ant Target – a fixed series of ant tasks in a specified
order that can depend on other named targets. Targets
can depend only on other targets, not on projects or
tasks. A target represents a particular item to be
created, it can be a single item like a jar, or a group of
items, like classes.
 Ant Task – something that ant can execute such as a
compile, copy or replace. Most tasks have very
convenient default values.

 Each build file should contains one project which contains
the targets and the tasks to perform.
 A project has three attributes:
 Each project defines one or more targets. A target is a set
of tasks you want to be executed. When starting Ant, you
can select which target(s) you want to have executed.
When no target is given, the project's default is used.
Attribute Description Required
name The name of the project. No
default The default target to use when no target is supplied. No
basedir The base directory from which all path calculations are done. No

 A target is a container of tasks that cooperate to reach
a desired state during the build process.
 Targets can depend on other targets and Apache Ant
ensures that these other targets have been executed
before the current target.
 A target has the following attributes:
Attribute Description Required
name The name of the target. Yes
depends A comma-separated list of names of targets on
which this target depends.
No
if The name of the property that must be set in
order for this target to execute.
No
unless The name of the property that must not be set in
order for this target to execute.
No
description A short description of this target's function. No

 A task is a piece of code that can be executed.
 We have inbuilt tasks available for all the basic functions
needed for the build creation and automation.
 File Tasks:
<copy>, <concat>, <delete>, <filter>, <fixcrlf>, <get>
 Compile Tasks:
<javac>, <apt>,<rmic>
 Archive Tasks:
<zip>, <unzip>,<war>,<unwar>,<ear>
 Testing Tasks:
<junit>,<junitreport>
 Miscelleneous Tasks:
<echo>,<javadoc>,<sql>

 Build File is an XML file which contains all the
configuration which is executed by ANT to create
build and performing other Tasks.
 The Sample Build file to create a build is attached
below:

 EXEC is an inbuilt task in Ant which helps us to run
any executable through ANT.
 Sample Execution of MQL
<target name="exec-mql">
<exec executable="mql -c">
<arg value="set context user creator;compile prog
* force update;"/>
</exec>
</target>

 Sometimes executing SQL queries also is a part of
application build. In that case ANT can help you to
automate the SQL execution as a part of ANT build.
 Connecting to Database:
<sql
driver="org.database.jdbcDriver”
url="jdbc:database-url”
userid="sa”
password="pass”
src="data.sql”
/>
 Here src conatins the sql script to be executed.

 Executing Query:
<sql
userid="sa”
password="pass”>
truncate table some_other_table;
</sql>

 Executing Query:
<sql
userid="sa”
password="pass” >
<transaction src="data1.sql"/>
<transaction>
truncate table some_other_table;
</transaction>
</sql>
