我升级了AS,错误开始出现
我看着每个地方,我无法解决问题
apply plugin: 'com.android.application'
android {
buildToolsVersion "26.0.2"
compileSdkVersion 26
defaultConfig {
applicationId "com.student.myapplication"
minSdkVersion 23
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {

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

}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7-26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
这是我的build.gralde(项目),离线未选中,我做了无效并重新启动没有工作,
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
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
}
这意味着什么无法解决依赖?这是我将存储库添加到gradle(app)时得到的

我看着gradle控制台,我找到了问题所在的链接,我点击了它们,然后在浏览器中打开并显示错误404 gradle console
