:A ''project '' has three attributes: '''name''': the name of the project. '''default''': the default target to use when no target is supplied. '''basedir''': the base directory from which all path calculations are done
: Each project defines one or more targets which are a set of task elements you want to execute
: When starting ant, you can select which target(s) you want to have executed
:A ''target '' has the following attributes: '''name''': the name of the target. '''depends''': a comma-separated list of names of targets. '''if''': the name of the property that must be set in order for this target to execute
:It should be noted, however, that Ant's depends attribute only specifies the order in which targets should be executed - it does not affect whether the target that specifies the dependency(s) gets executed if the dependent target(s) did not (need to) run.
:Note:The if and unless attributes only enable or disable the target to which they are attached. They do not control whether or not targets that a conditional target depends upon get executed. In fact, they do not even get evaluated until the target is about to be executed, and all its predecessors have already run. (See code below)<source lang=java><target name="myTarget" depends="myTarget.check" if="myTarget.run"> <echo>Files foo.txt and bar.txt are present.</echo></target> <target name="myTarget.check"> <condition property="myTarget.run"> <and> <available file="foo.txt"/> <available file="bar.txt"/> </and> </condition></target></source>:A project can have a set of properties:A '''NOTE'property''has a name and a value; the name is case-sensitive. Properties may be used in the value of task attributes. This is done by placing the property name between "${" and "}" in the attribute value. Example:::If "builddir" property with the value “c:/test",::This could be used in an attribute like this: ${builddir}/classes::This is resolved at run-time as c:/test/classes<source lang=java><project name="MyProject" default="init" basedir="."> <description> simple example build file </description> <!-- set global properties for this build --> <property name="src" location="src"/> <property name="build" location="build"/> <target name="init"> <!-- Create the build directory structure used by compile --> <mkdir dir="${build}"/> </target> <target name="compile" depends="init" description="comp-source "> <!-- Compile the java code from ${src} into ${build} --> <javac srcdir="${src}" destdir="${build}"/> </target> <target name="clean" description="clean up" > <!-- Delete the ${build} directory tree --> <delete dir="${build}"/> </target></project></source> ==ANT & Mercurial==:[http://ant4hg.free.fr/index.html ANT4HG] is an ANT task for HG ( mercurial ).: How to add ant4hg tasks to ant:::1- Download binaries. Latest version is ant4hg V0.07. It has been released with ant 1.8.0 and hg 1.5.1. Source code and binaries are available on the [http://sourceforge.net/projects/ant4hg/files/SourceForge download page].::2- Copy ant4hg-Vx.y.jar to the ant lib directory::3- Consider using : <code> <taskdef resource="net/sourceforge/ant4hg/taskdefs/antlib.xml"/></code> instead of: <code> <taskdef resource="net/sourceforge/ant4hg/antlib.xml"/> </code>.::4- Available tasks and the instruction of using them can be found in this [http://ant4hg.free.fr/specifications.html documentation]. ==Tips==: In Cygwin in the ''build'' folder. Just typing <code>ant</code>, will build the default target of the project. But typing <code>ant assign1.test</code> for example, will start from mentioned target.
:Also, option -f will build any files that's not named ''build.xml'' e.g. <code>ant -f buildHudson.xml</code>
