failed to resolve: com.android.support:appcompat-v7:27.+ 解决方法。新创建一个android studio project.出现了failed to resolve: com.android.support:appcompat-v7:27.+问题。
我的工作环境是 android studio 2.3.3。
app 下的 build.gradle文件内容如下:
apply plugin: 'com.android.application' android { compilesdkversion 27 buildtoolsversion "27.0.3" defaultconfig { applicationid "com.bestgo.facebookdownload" minsdkversion 15 targetsdkversion 27 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-v7:27.0.0' compile 'com.android.support.constraint:constraint-layout:1.0.2' testcompile 'junit:junit:4.12' }
project下的build.gradle文件内容如下:
????
// 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:2.3.3' // note: do not place your application dependencies here; they belong // in the inpidual module build.gradle files } } allprojects { repositories { jcenter() } } task clean(type: delete) { delete rootproject.builddir }解决方法:
?在project 下的build.gradle 文件里的 allprojects加入以下代码:
????????maven {
? ? ? ? ? ? url "https://maven.google.com"
? ? ? ? }
加入后的build.gradle文件如下:
// 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:2.3.3' // note: do not place your application dependencies here; they belong // in the inpidual module build.gradle files } } allprojects { repositories { jcenter() maven { url "https://maven.google.com" } } } task clean(type: delete) { delete rootproject.builddir }
