Error:No such property: GROUP for class: org.gradle.api.publication.maven.internal.deployer.DefaultGroovyMavenDeployer

注：參考：http://stackoverflow.com/questions/28450549/errorno-such-property-group-for-class-org-gradle-api-publication-maven-intern

問題大致出在庫工程 library/build.gradle 文件中的 apply from這句

apply plugin: 'com.android.library'

android {
    compileSdkVersion 17
    buildToolsVersion "19.1.0"

    defaultConfig {

        minSdkVersion 7
        targetSdkVersion 17
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:20.0.0'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

apply from: 'https://raw.github.com/twotoasters/gradle-mvn-push/master/gradle-mvn-push.gradle'

或者如

apply from: 'gradle-mvn-push.gradle'

刪掉這行即可
