Subject Re: Execute the target only if source files have changed
Date Fri, 02 Jan 2015 20:17:34 GMT
Oh, I have not read correctly the documentation of the <uptodate> task:
"multiple target files are specified using a nested <mapper> element"

So this is the correct target:
<target name="png-check">
	<uptodate property="png-uptodate">
		<srcfiles dir= "xcf" includes="*.xcf"/>
		<mapper type="glob" from="*.xcf" to="../png/*.png"/>
	</uptodate>
</target>

It seems to work :)
