"error: cannot find symbol" When using dep android library resource.

Created by: sean-kenny

It seems that we are not able to access a dependent android library resource from within another android library.

In this scenario we have two android libraries in the libs folder:

• lib1
• lib2

lib1 depends on lib2 for a resource, which it accesses directly via R. For example (excerpt from this file)

// lib_two_value comes from lib2 but is available via R in lib1 when using gradle
context.getString(R.string.lib_two_value)

When accessing a lib2 resource like this and running buck build //libs/lib1:lib, we get the following output:

> buck build //libs/lib1:lib

        return context.getString(R.string.lib_two_value);

Errors: 1. Warnings: 0.

To help as much as possible, I've created a test buck scenario with additional documentation on the problem here

Perhaps our buck configuration is not correct, or maybe buck does not provide the same lib1 -> lib2 resource merging as Gradle like we would normally expect.
