Google Closure Compiler SourceMap with multiple files

Question

How can I instruct google closure compiler to create a map file for my minified files that are in different folders preserving the right relative paths.

I cannot even specify a sourceRoot as option in sourcemap generation

I have a javascript file in /Js/common.js and then some other files in /Admin/js/plugin.js

"C:\Program Files\Java\jre6\bin\java.exe" -jar "..\SolutionItems\Javascript\compiler.jar" --js ".\Js\Common.js" --js ".\Admin\assets\js\plugins.js" %*  --source_map_format=V3 --js_output_file "./Admin/Asset/Js/admin.min.js" --create_source_map "./Admin/Asset/Js/admin.min.map"

this is the generated .map file

{
"version":3,
"file":"./Admin/Asset/Js/admin.min.js",
...
"sources":[".\\Js\\Common.js",".\\Admin\\assets\\js\\plugins.js"],
..
}

but it is misinterpreted by the browser because it use relative path from /Admin/Asset/Js/ and it try to find those js in /Admin/Asset/Js/js/common.js and /Admin/Asset/Js//Admin/Asset/js/common.js

-----UPDATE-----

For future reference: if you don't want to copy the closure compiler to the js folder (like me) it is enought to change the current folder before calling it.

cd c:\Website\Admin\Asset\js
"C:\Program Files\Java\jre6\bin\java.exe" -jar "c:\SolutionItems\Javascript\compiler.jar"--js "../../../Js/Common.js" --js "plugins.js"  --source_map_format=V3 --js_output_file "admin.min.js" --create_source_map "admin.min.map"

Run the compiler from the admin/assets/js/ folder. You can specify output paths for the other resources.
