Gradle - Recursive subprojects

Question

Assume I wanted to use Gradle with a project structure such as:

RootProject \-- SubProjectA     \-- SubProjectAA     \-- SubProjectAB 

How I would I achieve this?

What I tried is pretty straightforward. I've created all directories, with a structure described above:

RootProject \-- SubProjectA     \-- SubProjectAA         \-- build.gradle     \-- SubProjectAB         \-- build.gradle     \-- build.gradle     \-- settings.gradle \-- build.gradle \-- settings.gradle 

RootProject/settings.gradle:

include "SubProjectA" 

RootProject/SubProjectA/settings.gradle:

include "SubProjectAA", "SubProjectAB" 

There are two things I tried. First, I tried importing the project in Eclipse - which didn't detect SubProjectAA nor SubProjectAB. Stunned, I ran gradle projects in RootProject and got this output:

------------------------------------------------------------ Root project ------------------------------------------------------------  Root project 'RootProject' \--- Project ':SubProjectA' 

Still, thinking I made a mistake, I tried running the same command in SubProjectA, and got:

------------------------------------------------------------ Root project ------------------------------------------------------------  Root project 'RootProject' \--- Project ':SubProjectAA' \--- Project ':SubProjectAB' 

I assume that resolving subprojects doesn't go recursively. Is there any workaround for this?

Every example is masked with sample names, sorry if I made any mistake.

Thanks!

You can only have one settings.gradle. Typically it would contain something like:

include "SubProjectA:SubProjectAA" include "SubProjectA:SubProjectAB" 

More information can be found in the "multi-project builds" chapter of the Gradle User Guide.
