NAME
       build.xml - configuration file used by ant to build projects

DESCRIPTION
       The file	build.xml is the default configuration file used by ant	to de-
       termine target to build for a specific project. It  can	be  considered
       the ant equivalent of Makefile..

       The  format  of ant is XML and for each project a seperate file is con-
       structed.  The buildfile	consists of one	or more	tasks. An  example  is
       given below.

       <project	default="compile">

	 <target name="compile">
	   <javac srcdir="src">
	 </target>

       </project>

       This example has	one target and it is defaulted.	The target itself con-
       sists of	one task javac which compiles the files	in the src directory.

TARGETS
       Targets can depend on other targets. These dependencies	are  given  by
       the depends attribute of	the <target> element.

TASKS
       A  task	is  a piece of code that is executed.  Ant recognizes built-in
       task, optional tasks, but one can also write new	tasks.

       Built-in	tasks

       The built-in tasks are: Ant, AntCall, AntStructure,  Apply,  Available,
       Chmod,  Copy,  Cvs,  Delete, Deltree, Echo, Exec, ExecOn, Fail, Filter,
       FixCRLF,	GenKey,	Get, GUnzip, GZip, Jar,	Java, Javac, Javadoc/Javadoc2,
       Mail, Mkdir, Move, Patch, Property, Replace, Rmic, SignJar, Sql,	Style,
       Tar, Taskdef, Touch, TStamp, Unjar, Untar, Unwar, Unzip,	Uptodate, War,
       Zip

       Java   Executes	a  Java	class within the running (Ant) VM or forks an-
	      other VM if specified. Below are some of the  attibutes  to  the
	      <java> element:

	      classname	(required) the Java class to execute

	      fork if enabled triggers the class execution in another VM (dis-
	      abled by default)

	      jvm the command used to invoke the Java Virtual Machine, default
	      is  java.	 The  command is resolved by java.lang.Runtime.exec().
	      Ignored if fork is disabled.

	      Other arguments are classpath, classpathref, maxmemory,  failon-
	      error, dir and output.

       Javac  Compiles a source	tree within the	running	(Ant) VM.

	      srcdir (required)	location of the	java files

	      destdir location to store	the class files

	      debug indicates whether source should be compiled	with debug in-
	      formation; defaults to off

	      optimize indicates whether source	should be compiled with	 opti-
	      mization;	defaults to off

	      target  generate	class files for	specific VM version (e.g., 1.1
	      or 1.2).

	      includes comma-separated list of patterns	of files that must  be
	      included;	all files are included when omitted

	      excludes	comma-separated	list of	patterns of files that must be
	      excluded;	no files (except default excludes) are	excluded  when
	      omitted.

	      defaultexcludes  indicates  whether  default  excludes should be
	      used (yes	| no); default excludes	are used when omitted.

	      Other arguments are includesfile,	excludesfile, classpath, boot-
	      classpath,  classpathref,	 bootclasspathref,  extdirs, encoding,
	      deprecation, verbose, includeAntRuntime, includeJavaRuntime  and
	      failonerror.

Properties
       A  project  can have a set of properties, which consist of a name value
       combination. Within tasks they can be used by placing them between "${"
       and "}",	as in "${builddir}/classes".

       Built-in	Properties

       Ant  provides  access  to all system properties as if they had been de-
       fined using a <property>	task. For example, ${os.name} expands  to  the
       name of the operating system.

       basedir
	      the  absolute  path  of  the  project's basedir (as set with the
	      basedir attribute	of <project>).

       ant.file
	      the absolute path	of the buildfile.

       ant.project.name
	      the name of the project that is currently	executing; it  is  set
	      in the name attribute of <project>.

       ant.java.version
	      the  JVM	version	Ant detected; currently	it can hold the	values
	      "1.1", "1.2" and "1.3".

Classpath
       The classpath can be set	by using the <classpath> element:

       <classpath>
	 <pathelement path="${classpath}"/>
	 <pathelement location="lib/helper.jar"/>
	 <fileset dir="lib">
	   <include name="**/*.jar"/>
	 </fileset> </classpath>
