Ant构建和空目录

Question

由于某些原因，当我使用scp将文件从当前机器移动到使用ant的服务器时，它总是忽略空目录。

<scp todir="[e-mail]:/var/www/html" keyfile="${basedir}..keysprod_default.pem" trust="true">
<fileset dir="${staging.dir}" />
</scp>

为什么会这样？

您必须想出一个变通方法。Ant实现scp的方式意味着总是跳过空目录。

要点是Scp类是这样做的：

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

换句话说，只有当目录至少包含一个文件时，它才会处理该目录。

你可能会考虑为Scp任务代码提供一个补丁，但这意味着要定制Ant构建。

想到的另外两种方法是

• 通过填充占位符文件（部署后可以删除）使目录不为空
• 在单独的步骤中创建空目录
