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


       The  file  build.xml  is the default configuration file used by ant to determine 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  constructed.   The
       buildfile consists of one or more tasks. An example is given below.

       <project default="compile">

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


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


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


       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,   Basename,
       BuildNumber,  BUnzip2,  BZip2,  Checksum,  Chmod,  Concat,  Condition,  Copy, Cvs, Delete,
       Deltree, Dirname, Ear, Echo, Exec, Fail,  Filter,  FixCRLF,  GenKey,  Get,  GUnzip,  GZip,
       Import,  Input,  Jar, Java, Javac, Javadoc, Length, LoadFile, LoadProperties, Mail, Mkdir,
       Move, Nice, Parallel, Patch, PathConvert, Property,  Record,  Replace,  Rmic,  Sequential,
       SignJar,  Sleep, Sql, Style, Subant, Sync, Tar, Taskdef, Tempfile, Touch, TStamp, Typedef,
       Unjar, Untar, Unwar, Unzip, Uptodate, Waitfor, War, WhichResource, XmlProperty, Xslt, Zip

       Java   Executes a Java class within the running (Ant) VM or forks another 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 (disabled 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,  failonerror,  dir  and

       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 information; defaults
              to off

              optimize indicates whether source should be compiled with optimization; defaults to

              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,   bootclasspath,
              classpathref,    bootclasspathref,   extdirs,   encoding,   deprecation,   verbose,
              includeAntRuntime, includeJavaRuntime and failonerror.


       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 defined using a
       <property> task. For example, ${} expands to the name of the operating system.

              the absolute path of the project's basedir (as set with the  basedir  attribute  of

              the absolute path of the buildfile.

              the version of Ant.
              the  name  of  the  project  that  is  currently  executing;  it is set in the name
              attribute of <project>.
              the JVM version Ant detected; currently it can hold the  values  "1.1",  "1.2"  and


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

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