Failed to deploy site due to handling of local directories?

[jdolan]

I've configured this wagon for all distribution management channels, including site:

        <repository>
            <id>aws-release</id>
            <url>s3://reel-web-service/release</url>
        </repository>
        <snapshotRepository>
            <id>aws-snapshot</id>
            <url>s3://reel-web-service/snapshot</url>
        </snapshotRepository>
        <site>
            <id>aws-site</id>
            <url>s3://reel-web-service/site</url>
        </site>
    </distributionManagement>

Deploying of snapshots (and presumably releases) works fine. However, when running mvn site:deploy, the process creates the site folder in the target bucket, but fails to create apidocs due to what I believe to be a local directory recursion issue:

[DEBUG] File name has no extension, mime type cannot be recognised for: apidocs

This, despite the fact that target/site/apidocs is present, readable, and full of Javadocs. Really strange behavior. Anyone seen this before?

Yes. This appears to be due to AbstractWagon#putDirectory passing all results of File#listFiles() to put(), despite the fact that listFiles() returns entries for both files and folders.
