我使用android studio 3.0.0版。
更新前我使用SDK管理器更新支持库。但更新后的android studio 3我应该通过https://dl.google.com/dl/android/maven2/
进行更新。所以我需要支持库26.1.0。
on async gradle我有这个错误:
Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve junit:junit:4.12.
Could not resolve junit:junit:4.12.
Required by:
project :app > com.android.support.test:runner:1.0.1
> Could not resolve junit:junit:4.12.
> Failed to download SHA1 for resource 'https://dl.google.com/dl/android/maven2/junit/junit/4.12/junit-4.12.pom'.
> For input string: "<!"
为什么无法下载:https://dl.google.com/dl/android/maven2/junit/junit/4.12/junit-4.12.pom
?
我使用代理但无法下载。
此错误显示所有依赖项库(appcampatv7,设计,annonations等)
如何解决此问题无法下载资源的SHA1 ?
更新:
// 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:3.0.0'
// 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
}
和
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.example.testtesttest"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
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'
implementation 'com.android.support:design:26.1.0'
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'
}

经过大量搜索后解决了这个问题。在gradle.propertices
文件集中代理http
和https
并再次同步。
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyPort=12345
org.gradle.jvmargs=-Xmx1234m
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=12345
