with current ant it is difficult to do exactly what you want,
I normally do the following:
Pick a file that Sablecc allways changes when it
is run - ${targetdir}/lexer/Lex.java for example.
Use ant-contrib's outofdate task.
<ac:outofdate>
<sourcefiles path="${grammer.file}"/>
<targetfiles path="${targetdir}/lexer/Lex.java"/>
<sequential>
<sablecc grammer="${grammer.file}" targetdir="${targetdir}"/>
</sequential>
</ac:outofdate>
Ant 1.7.1 is adding in a "erroronmissingdir" attribute to filesets, this
means that one can do:
<ac:outofdate>
<sourcefiles path="${grammer.file}"/>
<targetfiles>
<path path="${targetdir}"/>
<fileset dir=${targetdir}" erroronmissingdir="false"
includes="**/*.java"/>
</targetfiles>
<sequential>
<sablecc grammer="${grammer.file}" targetdir="${targetdir}"/>
</sequential>
</ac:outofdate>
which is more what you want.
