How can I make sure that an included subproject runs before the main project in Gradle?

I have two Gradle projects with the following directory structure:

/baseDir
  /first
  /first/build.gradle
  /second 
  /second/build.gradle
  /second/settings.gradle

settings.gradle looks like this: 

includeFlat "first"

When I do gradle build the second project is compiled after the first (main) project. I tried in the first project's build.gradle:

dependencies {
  compile project(':first')
}

When doing gradle build I get an error that dependencies declared in the first project could not be found in the second one.

What I need is the following. When I do gradle buildon the second project I want that the first project will be build first and that first.jar is used as a dependency in the second project.

How can I do that?

Edit: When I set the following in my second project's settings.gradle: 

includeFlat "first", "second"

then I get the following error while doing graddle clean:

FAILURE: Build failed with an exception.

* What went wrong:
Could not select the default project for this build. Multiple projects in this build have project directory '/Users/mg/Documents/Grails/GGTS3.6.3-SR1/second': [:, :second]
> Multiple projects in this build have project directory '/Users/mg/Documents/Grails/GGTS3.6.3-SR1/second': [:, :second]

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Edit: I create a sample project form demonstration: https://github.com/confile/Gradle-MultiProject-Test

you can let the build task depend on the build task of another project:

build{
    dependsOn ':first:build'
}

Try this project settup:

root
  settings.gradle
  gradle.build
  first
    gradle.build
  second
    gradle.build

and put this in settings.gradle of your root:

include 'first'
include 'second'

You should move the block 

dependencies {
  compile project(':first')
}

to the second project's build.gradle. This will build the first project and before the second project and second project could use first project's classes.
