FTPUpload single files with options

[KKacer]

Your FTP upload examples shows 2 scenarios:
Upload a file.

Your Example 1:

  <FtpUpload 
            LocalFile="MSBuild.Community.Tasks.zip" 
            RemoteUri="ftp://localhost/" />

Your Example 2:
Upload all the files in an ItemGroup:

  <FtpUpload
            Username="username"
            Password="password"
            UsePassive="true"
            RemoteUri="ftp://webserver.com/httpdocs/"
            LocalFiles="@(FilesToUpload)"
            RemoteFiles="@(FilesToUpload->'%(RecursiveDir)%(Filename)%(Extension)')" />

(I am using your setup.msi (v1.5))
Can't understand your example 1,
In your example you didn't provide u/p, and use passive, so I added them in my below example
I tried the below scenario:

  <Target Name="FTPOneFile" AfterTargets="ZipMaker">
    <FtpUpload
        Username="xxx"
        Password="xxxx"
        UsePassive="true"
        RemoteUri="ftp://xxxxx"
        LocalFile="$(ZipFile)"
    />
  </Target>

When running, it says RemoteFiles property is necessary and is missed here.
But I don't have multiple files, I want to upload only a single file, but with full set of properties.
Adding below line also will not solve the issue will give other issues about RecursiveDir

<!--RemoteFiles="$(ZipFile)"-->
