[jruby-user] File to import not found or unreadable: compass/reset, Why?

Hi,

I following the following link to create single runnable jar containing
sass, compass, and jruby:
   http://seanchenxi.com/java/sass-compass-jruby-single-jar/
then I use:
   java -jar  jcompass.jar -S compass create MY_JPROJECT
to create a project. I got the following error message:
    error MY_JPROJECT/sass/screen.scss (Line 6: File to import not found or
unre
adable: compass/reset.
Load paths:
  Compass::SpriteImporter
  C:/projects/f5/jsass/MY_JPROJECT/sass

file:C:/projects/f5/jsass/jcompass.jar!/gems/compass-core-1.0.1/stylesheets)
Compilation failed in 1 files.

I don't know what happened for this error. I check that compass/_reset.scss
exsited in the directory "gems\compass-core-1.0.1\stylesheets" in
jcompass.jar.

How to solve it?

I use JDK jdk1.8.0_11 on Windows 8.

Thanks for your help?
