Ant 构建和清空目录

Question

由于某种原因，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="ec2-user@xx.x.x.xxx:/var/www/html" keyfile="${basedir}\..\keys\prod_default.pem" trust="true">
<fileset dir="${staging.dir}" />
</scp>

为什么会这样？

您必须想出一个解决方法。 Ant 实现 scp 的方式意味着总是会跳过空目录。

它的要点是 Scp 类这样做：

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

换句话说，它只处理包含至少一个文件的目录。

您可能会考虑使用patch for the Scp task code，但这意味着定制的 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）使目录非空
• 在单独的步骤中创建空目录
