Gradle SSH plugin copying parent folder and not just files

Question

I'm using this Gradle SSH plugin. It has a method put that will move files from my local machine to the machine the session is connected to.

My app is fully built and exists in build/app and I'm trying to move it to /opt/nginx/latest/html/ such that the file build/app/index.html would exist at /opt/nginx/latest/html/index.html and that any subfolders of build/app are also copied over.

My build.gradle:

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath 'org.hidetake:gradle-ssh-plugin:1.1.4'
  }
}

apply plugin: 'org.hidetake.ssh'

remotes {
  target {
    host = '<my target vm>'
    user = 'user'
    password = 'pass'
  }
}

...

task deploy() << {
  ssh.run {
    session(remotes.target) {
      put from: 'build/app/', into: '/opt/nginx/latest/html/'
    }
  }
}

As I have it above, it's putting all the files into /opt/nginx/latest/html/app. If I change the from to use fileTree(dir: 'build/app') then all the files get copied over but I lose the file structure, i.e. build/app/scripts/main.js gets copied to /opt/nginx/latest/html/main.js instead of the expected /opt/nginx/latest/html/scripts/main.js.

How can I copy the CONTENTS of one directory (not the directory itself) into the target directory while retaining folder structure?

Answer 1

You could create a FileTree object for your build/app directory and then ssh your entire tree structure to your remote instance:

FileTree myFileTree = fileTree(dir: 'build/app')

task deploy() << {
  ssh.run {
    session(remotes.target) {
      put from: myFileTree.getDir(), into: '/opt/nginx/latest/html/'
    }
  }

It should copy your structure and files like:

// 'build/app'         -> '/opt/nginx/latest/html/
// 'build/app/scripts' -> '/opt/nginx/latest/html/scripts/'
// 'build/app/*.*'     -> 'opt/nginx/latest/html/*.*'
// ...

Looking through the plugin's code, it says:

    static usage = '''put() accepts following signatures:
        put(from: String or File, into: String)  // put a file or directory
        put(from: Iterable<File>, into: String) // put files or directories
        put(from: InputStream, into: String)     // put a stream into the remote file
        put(text: String, into: String)          // put a string into the remote file
        put(bytes: byte[], into: String)         // put a byte array into the remote file'''

You're using option #1 where you are providing a File (which can also be a directory), while you should be using #2, which would be an iterable list of build/app's children. So I would try:

put (from: new File('build/app').listFiles(), into: '/opt/nginx/latest/html/')

Edit: Alternatively,

new File('build/app').listFiles().each{put (from:it, into:'/opt/nginx/latest/html/')}

You could add a wildcard to copy all files in the folder:

put from: 'build/app/*', into: '/opt/nginx/latest/html/'
