Android Studio 3.0.1 gradle编译报错 Error : unable to resolve dependency for app@

在app目录下build.gradle中引用了第三方类库,gradle编译时不断报错,无法resolve第三方类库,或者无法download第三方类库

    
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'io.reactivex.rxjava2:rxjava:2.1.14'
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
    implementation 'com.squareup.retrofit2:adapter-rxjava:2.4.0'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
}

上网查询可能是网络原因,解决办法如下:

1. 检查网络连接是否正常,正常继续往下执行步骤2

2.关闭所有Android Studio项目并且重启Android Studio

3.重新打开刚才gradle编译出错的项目然后重新编译gradle,编译通过,解决该问题
