Error: "The specified key does not exist" when passing S3 prefix as the only value of <keys> field.

When I pass the S3 prefix of the objects that I want downloaded before packaging, I get the following error:

Failed to execute goal com.gkatzioura.maven.cloud:s3-storage-wagon:2.3:s3-download (download-multiple-files-to-one-directory) on project TestProject: Execution download-multiple-files-to-one-directory of goal com.gkatzioura.maven.cloud:s3-storage-wagon:2.3:s3-download failed: The specified key does not exist. (Service: Amazon S3; Status Code: 404; Error Code: NoSuchKey; Request ID: REDACTED; S3 Extended Request ID: REDACTED) -> [Help 1]

The execution config is as follows:

<execution>
    <id>download-multiple-files-to-one-directory</id>
    <phase>prepare-package</phase>
    <goals>
        <goal>s3-download</goal>
    </goals>
    <configuration>
        <bucket>plugins-bucket</bucket>
        <downloadPath>WebContent\WEB-INF</downloadPath>
        <keys>Plugins</keys>
    </configuration>
</execution>

Going through the code in S3DownloadMojo.java I have come across the following lines:

if (keys.size()==1) {
    downloadSingleFile(amazonS3,keys.get(0));
    return;
}

Here downloadSingleFile() is set to only download a single file if the number of keys given is one. Could this be enhanced to recursively fetch all objects under the given prefix via another configuration parameter?

I agree this is needed
