In ant, when you echo an unset property, such as myproperty, ant echoes
${myproperty}.
This is maybe an annoying feature, but this is the way it works.
yes
Maybe there are in the properties which ant defines automatically already some properties which suit you. Add <echoproperties/> in you build file to see **All*** the properties currently set.
i will try this.
If you want a property to be set always, here an example
<condition property="isDos" value="true"> <os family="dos"/> </condition> <!-- this will only applied if isDos has not been set previously --> <property name="isDos" value="false"/> <echo message="dos is ${isDos}"/>
aha, good trick!
Properties in ant are immutable. Once you have set them once, they do not change. So the trick is to give default values to properties *** after *** having used for instance condition, which will only set the value of a property under ... the conditions of your choice.
got it!
thanks
