How to build a project with transitive project dependencies in gradle

I'm new to gradle, and I'm trying using gradle to build projects in Eclipse with Gradle IDE plugin.(Gradle version 2.3, Gradle IDE version 3.6.3)
I have an example of three Java projects in flat layout with dependency A->B->C. The project A, B and C know nothing about the others except the direct dependency. I need to build each of the projects.
I successfully made B depend on C with settings.gradle file in Project B to include Project C, and the build of B and C was successful.

include ":C"
project(':C').projectDir = new File(settingsDir, '../C')

Then I tried adding dependency A -> B with the same way I had tried with B->C (by adding the settings.gradle file). But this time the build of project A failed with error: cannot find C under /B. The settings.gradle file in project B was not read.
I don't want to add dependency info of C to A to build A, for A should not know about C. I searched and could not get the answer. Is there a way to resolve this kind of transitive project dependency in gradle? Thanks very much.

I have solved the problem myself with the studying of gradle DSL document and some groovy. I add the following code in my settings.gradle files to apply settings.gradle of the subproject if it exists. 

def applySettings = {
    def file = new File(project(it).projectDir, "settings.gradle");
    if (file.exists()) {
        apply "from" : file.toURI()
    }
}

applySettings ':B'
