"The container 'Android Dependencies' references non existing" when running project in Eclipse

I am trying to get a gradle build of my project, so I have exported it from unity and imported it to Eclipse with the aim of exporting a gradle build. I have imported the UnityPlayerActivity and unity-android-resources folders, but when I run the project I receive the following build path error:

The container ‘Android Dependencies’ references non existing library ‘/Documents/MasterWorkspace/Android/Ugh/unity-android-resources/bin/unity-android-resources.jar’

Looking in the unity-android-resources folder, there is no bin folder and no unity-android-resources.jar in another folder. Has anyone seen this before?

Does Eclipse support gradle? i thought its only used in Andoid Studio …
