How to copy directory via scp within gradle task?

What is a clean and elegant way to copy a bunch of files via scp with Gradle?

使用 Gradle 通过 scp 复制一堆文件的干净优雅的方法是什么？

Two ways I currently see are:

我目前看到的两种方式是：

• Using Apache Wagon, as described here: http://markmail.org/message/2tmtaffayhq25g4s
• Executing scp via command line with the Exec task

• 使用 Apache Wagon，如下所述：http: //markmail.org/message/2tmtaffayhq25g4s
• 使用 Exec 任务通过命令行执行 scp

Are there any better (more obvious) ways to approach this?

有没有更好（更明显）的方法来解决这个问题？

From a project of mine that I use to SCP files to an EC2 server. The jar files there are local files that are part of my project, I forget where I got them from. There's probably a more concise way of doing all this, but I like to be very explicit in my build scripts.

从我使用的一个项目到 SCP 文件到 EC2 服务器。jar 文件是我项目的一部分的本地文件，我忘记了我从哪里得到它们。可能有一种更简洁的方式来做这一切，但我喜欢在我的构建脚本中非常明确。

configurations {
  sshAntTask
}

dependencies {
  sshAntTask fileTree(dir:'buildSrc/lib', include:'jsch*.jar')
  sshAntTask fileTree(dir:'buildSrc/lib', include:'ant-jsch*.jar')
}

ant.taskdef(
  name: 'scp',
  classname: 'org.apache.tools.ant.taskdefs.optional.ssh.Scp',
  classpath: configurations.sshAntTask.asPath)

task uploadDbServer() {
  doLast  {
    ant.scp(
      file: '...',
      todir: '...',
      keyfile: '...' )
  }
}

A few years after the original question, I like the Gradle SSH Plugin. A small quote of its extensive documentation:

在最初的问题几年后，我喜欢Gradle SSH Plugin。其广泛文档的一小段引述：

We can describe SSH operations in the session closure.

session(remotes.web01) {
  // Execute a command
  def result = execute 'uptime'

  // Any Gradle methods or properties are available in a session closure
  copy {
    from "src/main/resources/example"
    into "$buildDir/tmp"
  }

  // Also Groovy methods or properties are available in a session closure
  println result
}

Following methods are available in a session closure.

• execute- Execute a command.
• executeBackground- Execute a command in background.
• executeSudo- Execute a command with sudo support.
• shell- Execute a shell.
• put- Put a file or directory into the remote host.
• get- Get a file or directory from the remote host.

我们可以在会话关闭中描述 SSH 操作。

session(remotes.web01) {
  // Execute a command
  def result = execute 'uptime'

  // Any Gradle methods or properties are available in a session closure
  copy {
    from "src/main/resources/example"
    into "$buildDir/tmp"
  }

  // Also Groovy methods or properties are available in a session closure
  println result
}

以下方法在会话关闭中可用。

• execute- 执行命令。
• executeBackground- 在后台执行命令。
• executeSudo- 在 sudo 支持下执行命令。
• shell- 执行一个shell。
• put- 将文件或目录放入远程主机。
• get- 从远程主机获取文件或目录。

...and allows for, for example:

...并允许，例如：

task deploy(dependsOn: war) << {
  ssh.run {
    session(remotes.staging) {
      put from: war.archivePath.path, into: '/webapps'
      execute 'sudo service tomcat restart'
    }
  }
}
