<uptodate> task might help you to do what you want.
I use it for example to avoid generating code blindly.

Alternatively a large build file is normally splitted into several targets that 
depends on each other, so there is normally always the possibility to perform a 
somewhat atomatic operation, it is up to the build.xml writer to do this 
correctly.
For example, assuming I have a dist target that takes time and that it fails, 
to compile, I can simply compile or jar...
<target name="prepare"/>
<target name="compile" depends="prepare"/>
<target name="jar" depends="compile"/>
<target name="javadoc"/>
<target name="dist" depends="jar,javadoc"/>
