The collection could not be built as it contains no data. Make sure that at least one of the directories or files you specified on the source data page exists and is of a type or (in the case of a directory) contains files of a type, that Greenstone can process.
But I can not see the mistake, I put a URL there,and it is a valid URL.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Please download and install Greenstone v2.50 and use the Greenstone Librarian Interface for building your collections. This is a much more powerful and easy to use program than the Collector, and gives you more information if anything goes wrong.
On Windows, a shortcut to the Librarian Interface is added to the Start Menu under the Greenstone Digital Library folder.

Also, I tried to put a file there, which is a PDF file. It always shows that the input sources is unavailable.
