Failed to resolve: com.android.support:appcompat-v7:27.+ 报错解决方法
app module build.gradle dependencies中默认配置如下：
dependencies {
compile fileTree(dir:'libs',include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
excludegroup:'com.android.support',module:'support-annotations'
})
compile'com.android.support:appcompat-v7:27.+'
compile'com.android.support.constraint:constraint-layout:1.0.2'
testCompile'junit:junit:4.12'
}
Studio 2.3版本应该在Root Project build.gradle allprojects配置如下：
allprojects {
repositories {
jcenter()
maven { url "https://maven.google.com" }
}
}
Studio 3.0版本应该在Root Project build.gradle allprojects配置如下：
allprojects {
repositories {
jcenter() google() }
}
