I am studying Apache Ant to try to change some lines of code inside files, but so far I have not found anything about it in the official documentation, so the maximum I can do is rename files like this example
<move todir="my/src/dir" includeemptydirs="false">
<fileset dir="my/src/dir"/>
<mapper type="glob" from="*.default.properties" to="*.local.properties"/>
I wanted to know if they have already gone through this and how can I resolve it.
