A common problem. In my case this works:

In "android-support-v7-appcompat" project:

-Delete “android-support-v7-appcompat” from Package explorer.
-Import again and check “Copy into workspace”
-In Properties -> Android -> in Project build target, uncheck Android 2.2 and check Android 4.1.2
-In Java build path, uncheck if you have any .jar library, and uncheck the Dependences

In other hand, the proyect that uses “android-support-v7-appcompat”

in Propiedades -> Android add the library, but uncheck "IsLibrary”.
-In Android -> Project build tarjet check Android 4.0.
-In "Java Build Path" -> Order and Export -> Unchecked the .jar library
-Finally do a “Project -> Clean” both projects
