Question

I’m using Ant 1.8.2. Given a directory, how do I add an “.html” extension to all files in the directory and its sub-directories only if those files don’t already have an .html extension?

Answer 1

There’s an example in the Ant move task docs for renaming .bak files that is similar, here it is adjusted for .html files under a directory called my_dir:

<move todir="my_dir" includeemptydirs="false">
    <fileset dir="my_dir">
        <exclude name="**/*.html" />
    </fileset>
    <mapper type="glob" from="*" to="*.html" />
</move>

The fileset excludes files that already have the target extension, the mapper defines the renaming pattern.
