Android Question Maven artifact not found

Hello

I get the error:

Maven artifact not found: G/\Android\android-sdk\extras\android\support\v4\android-support-v4

when i add this to my project

#AdditionalJar: G:\Android\android-sdk\extras\android\support\v4\android-support-v4.jar

Please look at the rror msg it says : Maven artifact not found: G/\Android\
