Antora does not copy attachment file to build folder if the file does not have extension.
Hello,
If a file under modules/amodulename/assets/attachments
does not have a proper extension such as script file, Antora does not copy them to the build folder during generation process so file can not be linked.
With link:{attachmentsdir}/filename[link content]
syntax (without extension in the filename) in modules/amodulename/pages/apage.adoc
document, Antora can not create a proper link since the file is not being copied to the build folder.
I think this is a bug.
