[gradle-user] Replace properties in a file

[Ignacio Coloma]

Is there any way of replacing properties in a file while it's being copied?
I have a file that contains

docBase="${project.projectDir}/src/web"

And I want to copy it and replace the properties automatically. With ant, I
would have used a filterchain (expandproperties) but with gradle I'm a
little lost:

ant.copy(
        file: "fromfile.xml",
        tofile: "tofile.xml"
        //chain:   << magic happens here
        )

Note that I'm not using any wildcards here, so a pure Groovy solution may
also solve my problem.
