Android Studio：Gradle无法解决依赖关系

我正在尝试构建导入的项目。

进程“ Gradle：解决依赖关系'：app：_debugCompile'”仅继续运行

所以我搜索了互联网，发现我需要在终端中运行gradlew build --stacktrace --debug

然后我看到，在某个时候Android Studio试图做到这一点：

Connecting to 10.153.20.12:8080

然后连接失败，构建也失败：

 FAILURE: Build failed with an exception.
 * What went wrong:
 A problem occurred configuring root project 'MyProject'.
 > Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:1.2.3.
 Required by:           
     :MyProject:unspecified

     > Could not get resource 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.2.3/gradle-1.2.3.pom'.
        > Could not GET 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.2.3/gradle-1.2.3.pom'.
           > Connection to http://10.153.20.12:8080 refused

PS：其他项目的建立没有问题

PPS：同一件事发生在不同的计算机上

这是我的app：build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "ru.myrunner.myrunner"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.pkmmte.view:circularimageview:1.1'
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:cardview-v7:22.2.1'
    compile 'com.google.android.gms:play-services:7.8.0'
    compile 'com.android.support:recyclerview-v7:22.2.1'
}

编辑：显然，问题出在

compile 'com.pkmmte.view:circularimageview:1.1'
