【问题描述】：
当我开始一个新项目时，弹出这些错误
Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.support:appcompat-v7:26.1.0.
Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.android.support.test.espresso:espresso-core:3.0.1.

Unable to resolve dependency for ':app@releaseUnitTest/compileClasspath': Could not resolve com.android.support:appcompat-v7:26.1.0.
这些是显示的错误。下面是我的 build.gradle(Module:app)
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "com.example.user.myapplication"
minSdkVersion 22
targetSdkVersion 26

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {

minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
buildToolsVersion '26.0.2'
}

androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-
core:3.0.1'
}
build.gradle(Project:myapp)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
gradle-wrapper.properties(Gradle 版本)

顺便说一句，我的 gradle 是 4.1，我的 android studio 是 3.0.1。 请帮助我如何解决这个问题。谢谢。
【问题讨论】：
-
您正在执行什么 gradle 任务导致这些错误消息？另外，您是否尝试过清洁和重建？
-
我正在尝试执行该应用程序，但尽管我清理并重建了项目，但错误仍然相同。详细信息说“连接超时”。
-
您也可以发布“root”
build.gradle文件吗？通常它位于app文件夹所在的项目根目录下。 -
连接超时：这意味着它试图从 Google 存储库中检索某些文件但无法检索。确保您的 PC 具有正常工作的 Internet。还要检查这个答案：stackoverflow.com/a/47306129/2949966

我认为我的外部 gradle 安装是 gradle 2.3.3
