【中文标题】Ant：如果不存在，则创建目录

【英文标题】：Ant: scp create directory if not exist

【问题描述】：

我正在使用它从 A 复制到 B。 但是，例如，如果文件夹 /config 不存在，它会给我一个例外。我该如何解决？我试过 mkdirs="true" 但它也会出错

<scp todir="$ftplogin@$ftpserver:$ftp-remote-dir/config" verbose="false" trust="true" failonerror="No">
            <fileset dir="$stuff/$stuff-version/config$config-files">
                <include name="*.*"/>               
            </fileset> 
        </scp>

【参考方案1】：

无法使用 scp 任务创建远程目录。 这是 scptransfer 的宏定义，它完成了传输所需的所有工作 从给定的 stagedirectory => 修复换行，createremote，deleteremote，如果 stagedir 为空则失败 ... 等等。 Macrodef 正在使用 ant 插件 Flaka，如果您不需要所有的花里胡哨，只需使用 sshexec task 和 mkdir -p 在 scp 之前创建您的远程目标目录。

【参考方案2】：

您可以在应对之前使用sshexec 在远程机器上创建目录树。 mkdir -p 如果不存在则创建目录。 (How to mkdir only if a dir does not already exist?)

<sshexec
    host="$host"
    username="$remote_user"
    password="$remote_password"
    command="mkdir -p $remote_dir_path"
    trust="true" />

在 scp 之前将其添加到您的目标
