ÉCHEC: la construction échoue avec une exception dans ionique

Je suis nouveau sur ionique et juste essayer de faire unsigned la construction de mon projet de démonstration à l'aide du soufflet mentionné commande :-

cordova build --version android

mais cette chose est de retour moi d'erreur lors de la construction de apk. Quelqu'un peut-il me dire ce que dois-je faire pour obtenir ce unsigned APk via la ligne de commande.

Voici mon message d'erreur :-

Et voici mon petit bout de code à partir de construire.gradle fichier :-

apply plugin: 'android'

buildscript {

        mavenCentral()
    }

    if (gradle.gradleVersion >= "2.2") {
        dependencies {
            classpath 'com.android.tools.build:gradle:1.0.0+'
        }
    } else if (gradle.gradleVersion >= "2.1") {
        dependencies {

        }
    } else {
        dependencies {

        }
    }
}

//Allow plugins to declare Maven dependencies via build-extras.gradle.
repositories {
    mavenCentral()
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.2.1'
}
