EXT closure doesn't work Gradle Android

Help/Discuss

I am trying to add some extra properties (constants) to my build scripts.

I have defined dependencies.gradle for storing dependencies and constants.

// Project repositories
allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}
ext {
    // Build Tools
    gradleVerison = '2.2.3'
    //Android


    buildDependencies = [
            gradle : "com.android.tools.build:gradle:${gradleVerison}",
    ]
}

And in my root build.gradle file I want to use defined ext properties like that

// Retrieve dependencies
apply from: 'buildsystem/dependencies.gradle'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath rootProject.ext.buildDependencies
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

But it won’t work

Error:(9, 0) Cannot get property 'buildDependencies' on extra properties extension as it does not exist

I have tried different variants

 def globalConfiguration = rootProject.extensions.getByName("ext")
globalConfiguration.getAt("buildDependencies")

project.ext.buildDependencies

project.buildDependencies

...

But still the same error. Please help to get it working. And please explain internals of this code. Thanks.

I’ve solved my problem like that

buildscript {
    apply from: "$rootProject.projectDir/buildsystem/buildscript.gradle"
    dependencies {
        classpath buildscriptDependencies.gradle
    }
}

Does it look ok ?
Could someone explain internals of this ?
Thx
