I don't believe there is any such automatic capability in ant.  You could
build it yourself if you were willing to do a (small) bit of work.

Here's my first idea how to do it. For each target that you want to not
rerun again or future runs of the build file, you put a <propertyfile> task
at the end that sets a property in a file which lets you know that the task
was run.  The target then uses the "unless" attribute to say it wont run if
the property is set.  Also you load the properties file at the beginning of
the project.  

Essentially:

<project name="test" default="main" basedir=".">
   <property file="incremental.properties" />

   <target name="main" depends="a,b" />

   <target name="reset">
	<delete file="incremental.properties"/>
   </target>

   <target name="a" unless="a-run" >
	<echo>running a</echo>
	<propertyfile file="incremental.properties">
	   <entry key="a-run" value="true"/>
	</propertyfile>
   </target>

   <target name="b" unless="b-run" >
	<echo>running b</echo>
	<propertyfile file="incremental.properties">
	   <entry key="b-run" value="true"/>
	</propertyfile>
   </target>

   <!-- do the same with other targets -->
</project>
