Eclipse / Gradle: Task 'Sync' does not synchronized linked files or folders

Question

I would to like synchronize two folders in my eclipse project with a gradle task.

The source folder is a linked resource. The destination folder a 'real' folder.

I choose the gradle Sync task to do the work, but no file or folder was copied to the traget folder.

The task in the gradle.build file:

task copyA2B(type: Sync) {
    from 'dest'
    into 'target'   
}

Any ideas?

Gradle Version: 4.10.2
