Ant build and empty directories

For some reason, when I use scp to move files from my current machine to the server using ant it always ignores empty directories.

<scp todir="[email protected]:/var/www/html" keyfile="${basedir}\..\keys\prod_default.pem" trust="true">
<fileset dir="${staging.dir}" />
</scp>

Why is the case?

You'll have to come up with a workaround. The way that Ant implements the scp means that empty directories are always skipped.

The gist of it is that the Scp class does this:

DirectoryScanner scanner = set.getDirectoryScanner(getProject());
Directory root = new Directory(scanner.getBasedir());
String[] files = scanner.getIncludedFiles();
if (files.length != 0) {
    ...
}

In other words, it only processes the directory if it contains at least one file.

There is a patch for the Scp task code you might consider, but that means a bespoke Ant build.

The two other approaches that come to mind are

  • make the directories non-empty by populating with placeholder files (which you can delete once deployed)
  • create the empty directories in a separate step
