问题：

在帮别人配置AS时，用的gradle编译是最新版本3.3，在离线（Office Mode）的状态下新建一个项目时出现以下错误：

Error: Failed to resolve: junit:junit:4.12
Failed to resolve: javax.inject:javax.inject:1
Failed to resolve: javax.annotation:javax.annotation-api:1.2
Failed to resolve: com.google.code.findbugs:jsr305:2.0.1
Failed to resolve: org.hamcrest:hamcrest-library:1.3
Failed to resolve: org.hamcrest:hamcrest-integration:1.3
Failed to resolve: com.squareup:javawriter:2.1.1

app中build.gradle文件：

apply plugin: 'com.android.application'

android 
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig 
        applicationId "test.app.stannah.com.uk"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    buildTypes 
        release 
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        
    


dependencies 
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', 
        exclude group: 'com.android.support', module: 'support-annotations'
    )
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'

原因及解决方法：

原因很简单，单纯的网络连接问题。解决办法就是将不需要的library去掉，将以下代码展示的库依赖去掉，重新编译即可。

compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', 
    exclude group: 'com.android.support', module: 'support-annotations'
)
testCompile 'junit:junit:4.12'
