I'm trying to copy additional files which are targets for hyper links in robot report file using setting "Other files to copy".

Source files layout is following:

log.html
output.xml
report.html
addition/file1.html
addition/subdir/file2.html

"Other files to copy" set to

addition/**/*.html

Actual result:
robot report files and files from addition dir copied to lastSuccessful/robot-plugin without subdirs like this:

lastSuccessful/robot-plugin/log.html
lastSuccessful/robot-plugin/output.xml
lastSuccessful/robot-plugin/report.html
lastSuccessful/robot-plugin/file1.html
lastSuccessful/robot-plugin/file2.html

this cause broken relative links from report.html to file1.html and file2.html when report.html is browsed from jenkins web-interface.

Expected result:
robot report files and files from addition dir copied to lastSuccessful/robot-plugin with subdirs like this:

lastSuccessful/robot-plugin/log.html
lastSuccessful/robot-plugin/output.xml
lastSuccessful/robot-plugin/report.html
lastSuccessful/robot-plugin/addition/file1.html
lastSuccessful/robot-plugin/addition/subdir/file2.html

I hope I just missed some configuration option or known workaround for this issue.
I believe it is usual to have additional artifacts linked from report.html not only in the same directory.
