Gradle构建无法从自定义Maven存储库获取依赖项

我在链接后的BitBucket上创建了一个自定义Maven存储库。当尝试使用Gradle在我的Android项目中使用依赖项时，出现以下错误

Executing tasks: [:app:compileDebugJava]

Configuration on demand is an incubating feature.
Relying on packaging to define the extension of the main artifact has been deprecated and is scheduled to be removed in Gradle 2.0

我更改了链接。但是直接打开链接将返回校验和。

下面是我的build.gradle

apply plugin: 'com.android.application'
apply plugin: 'maven'
android {
    compileSdkVersion 19
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.test.sampleapp"
        minSdkVersion 11
        targetSdkVersion 19
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}
repositories {
    mavenCentral()
    maven {
        credentials {
            username "[email protected]"
            password "test"
        }
        url "https://bitbucket.org/test/maven-repo/raw/master/repository/"
    }
}
dependencies {
    compile 'com.android.support:appcompat-v7:20.+'
    compile 'com.test.com:testCommon:1.0'
    compile files('libs/GoogleAdMobAdsSdk-6.4.1.jar')
}

我不确定我在做什么错。我也遵循了此链接。谁能帮我解决这个问题。

更新1：

当我检查〜.gradle文件夹时，即使在提供凭据后也无法登录并保存整个页面。当我将存储库从私有更改为公开时，代码开始工作。但是我不想公开我的回购。如何使gradle使用传递的登录凭据？

谢谢。
