gradle dependencie managment with sub dependencies (nested depenencies)

I have three projects 

../server/modelProject/
../client/apiProject/
../client/appProject/

The apiProject need to depends on modelProject and appProject need to depends on apiProject. Api need the models and the app need the api. Just a normal thing, i think :)

My modelProject have nothing special.

The apiProject setup looks like this:

settings.gradle

include ':app', 'models'
project(':models').projectDir = new File('../../server/modelProject')

build.gradle

dependencies {
    compile project(':models')
}

Last my appProject:

settings.gradle

include ':app', ':api'
project(':api').projectDir = new File("../client/apiProject")

build.gradle

dependencies {
    compile project(':api')
}

I expected that my appProject on which I'm working on, depend on api which depends on model so that I can use all models classes in my appProject too. But it isn't so.

I get the following error:

Project with path :models could not be found in projects ':api'.

So solve these problem I can expand the appProjects settings.gradle to:

include ':app', ':api', ':models'
project(':api').projectDir = new File('../client/apiProject')
project(':models').projectDir = new File('../../server/modelProject')

But this isn't a nice solution and not what I expected.

So my question: It this the normal behavior of gradle? Or do I make something wrong? Can I make any changes that appProject only depends on apiProject which will automatically include the `modelProject?

you need 1 top level settings.gradle in the root folder containing all of your modules if you're going to create dependencies between modules

Just one settings.gradle is enough. Your project file tree should be something like:

Project

  • client
    • apiProject
      • build.gradle
    • appProject
      • build.gradle
  • server
    • build.gradle
  • setings.gradle
  • build.gradle

settings.gradle ->

include ':app', ':api', ':models'

project(':app').projectDir = new File(rootProject.projectDir,'client/appProject')
project(':api').projectDir = new File(rootProject.projectDir,'client/apiProject')
project(':models').projectDir = new File(rootProject.projectDir,'server/modelProject')

And your dependency flow is you explained.

Your first settings.gradle file will not be used. From the gradle docs:

A multiproject build must have a settings.gradle file in the root project of the multiproject hierarchy. It is required because the settings file defines which projects are taking part in the multi-project build

So your second approach with listing all projects in one settings.gradle file is correct.
