子项目取决于Gradle中的根项目

Question

Can sub project dependent on or use some files or packages from the root project in gradle?

I have the following project:

root
├── project1
├── build.gradle
└── src
├── settings.gradle

I have the settings.gradle as following:

include 'project1'

The project1 need to use some files and packages from src of the root which is the root project, is there a way to do it?

Answer 1

I recommend this structure as it's more flexible and manageable. root will be just a wrapper and will contain subprojects only.

root
├── project1 (dependent on project 2)
|   |
|   |__build.gradle
|    
|
|__ project2
|   |
|   |__ src
|   |__ build.gradle
|   
├── build.gradle
├── settings.gradle

settings.gradle

include 'project1'
include 'project2'

EDIT: If you need to have dependency on root, use following dependency in project1 :

dependencies {
  compile project(':root')
}

In settings.gradle

rootProject.name = 'root'
include 'project1'
