я пытаюсь построить свой первый проект с Gradle, и я думаю, что мои файлы Gradle и настройки правильные.

используя только один модуль и библиотеки поддержки V4 + AppCompatBar.

Проект - build.gradle

allprojects {
    repositories {
        mavenCentral()
    }
}

Проект - настройки.града

include ':AssignmentTempos21'

Основной модуль - build.gradle

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }
}

dependencies {
    compile "com.android.support:support-v4:18.0.+"
    compile "com.android.support:appcompat-v7:18.0.+"
}

Вывод на консоль с флагом -i:

MacBook-Air-de-Cesar-2:AssignmentTempos21 menor$ ./gradlew -i clean assemble
