Or you get ant-contrib's new tasks (mostly working fine), and can do things
like (examples from production build files):
<if>
<istrue value="${verbose}" />
<then>
<echo message="Building ${ant.project.name}" />
<echo message=" on ${env.COMPUTERNAME}" />
<echo message=" at ${TIME_NOW} on ${TODAY}" />
<echo message=" from ${basedir}" />
<echo message=" using JDK ${java.vm.version}" />
</then>
</if>
or
<!-- Set various properties according to the build mode -->
<switch value="${buildmode}" caseinsensitive="true">
<case value="debug">
<property name="debug" value="true" />
<property name="configuration" value="Win32 Debug" />
<property name="baseconfig" value="shared.debug" />
</case>
<case value="release">
<property name="debug" value="false" />
<property name="configuration" value="Win32 Release" />
<property name="baseconfig" value="shared" />
</case>
<default>
<fail message="Invalid buildmode: ${buildmode}" />
</default>
</switch>
or
<if>
<not>
<uptodate targetfile="${buildmagic.jar}">
<srcfiles dir="${buildmagic.home}/src" includes="**/*.java" />
</uptodate>
</not>
<then>
<ant dir="${buildmagic.home}" target="jar" inheritAll="false" />
</then>
</if>
<taskdef name="which" classname="com.lgc.buildmagic.Which"
classpath="${buildmagic.jar}" />
<taskdef name="subant" classname="com.lgc.buildmagic.SubAnt"
classpath="${buildmagic.jar}" />
<taskdef name="lsync" classname="com.lgc.buildmagic.LocalSynchronize"
classpath="${buildmagic.jar}" />
<property name="-buildmagic-defined" value="true" />
--DD
PS: There are things that do not work that well though... It's all a matter
of experimenting ;-) Note that <if>/<switch>/etc... are not officially
supported by the Ant team, nor recommended. Report any problems to the
ant-contrib team (on SourceForge), of which at least one Ant committer
belongs to, thankfully ;-).

Are you sure that "every" target does ? I'm trying to use "unless" in the
<depend unless="my.property" .../> target, but I get this error:
build.xml:110: The <depend> task doesn't support the "unless" attribute.
