Gradle fails to resolve dependencies in Android Studio
提问by Timme van der Meer
Whenever I add a dependency from an remote repository (jcenter) in Android Studio 1.1 (OS X) I get the following error upon syncing Gradle:
每当我从 Android Studio 1.1 (OS X) 中的远程存储库 (jcenter) 添加依赖项时，同步 Gradle 时都会出现以下错误：
Error:(26, 13) Failed to resolve: <packagename:version>
My app's build.gradle is as follows: apply plugin: 'com.android.application'
我的应用程序的 build.gradle 如下：apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "nl.timmevandermeer.cargoapp"
minSdkVersion 19
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:support-v4:21.0.3'
compile 'com.google.android.gms:play-services:6.5.87'
compile 'org.json:json:20141113'
}
I have tried changing repositories (jcenter(), mavenCentral(), etc.), reinstalling Android Studio, JDK (7 and 8), changing Gradle version and Android SDK version, none of which worked. Upon running ./gradlew build I get:
我尝试过更改存储库（jcenter()、mavenCentral() 等）、重新安装 Android Studio、JDK（7 和 8）、更改 Gradle 版本和 Android SDK 版本，但都没有奏效。运行 ./gradlew build 后，我得到：
Could not resolve com.android.tools.build:gradle:1.1.0.
13:48:04.914 [ERROR] [org.gradle.BuildExceptionReporter] Required by:
13:48:04.915 [ERROR] [org.gradle.BuildExceptionReporter] :CargoApp:unspecified
13:48:04.932 [ERROR] [org.gradle.BuildExceptionReporter] >
org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
This is an error I get in other cases as well, for example when trying to use Intellij Idea instead of Android Studio. Running the app without the dependency does work though.
这也是我在其他情况下遇到的错误，例如在尝试使用 Intellij Idea 而不是 Android Studio 时。不过，在没有依赖项的情况下运行应用程序确实有效。

Top build.gradle:
顶部build.gradle:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.3'
}
}
App build.gradle:
应用程序build.gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "nl.timmevandermeer.cargoapp"
minSdkVersion 19
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
// compile fileTree(dir: 'libs', include: ['*.jar']) // <-- use gradle depedencies
compile 'com.android.support:appcompat-v7:22.0.0' // <-- brings in v4
// compile 'com.google.android.gms:play-services:7.0.0' // <-- will cause MultiDex exception, you need to choose which ones you want
// compile 'org.json:json:20141113' // <-- android comes with org.json
}
Multi-Dex Issue:
多 Dex 问题：
compile 'com.google.android.gms:play-services:7.0.0'is too big and should not be used directly. Please choose the modules you want here: http://developer.android.com/google/play-services/setup.html
compile 'com.google.android.gms:play-services:7.0.0'太大，不应该直接使用。请在此处选择您想要的模块：http: //developer.android.com/google/play-services/setup.html

A similar problem here, and when I choose Build -> Clean Project there is a "peer not authenticated" error.
这里有一个类似的问题，当我选择 Build -> Clean Project 时，会出现“对等方未验证”错误。
solved by using "http://jcenter.bintray.com/" instead of "https://jcenter.bintray.com/"
通过使用“ http://jcenter.bintray.com/”而不是“ https://jcenter.bintray.com/”解决
repositories {
jcenter({url "http://jcenter.bintray.com/"})
}
hope this work for you.
希望这对你有用。

Tested in UBUNTU - 14.04 ,
在 UBUNTU - 14.04 中测试，
>delete .androidstudio1.2 , .gradle , .android , Android studio project from home directory
> Launch using studio.sh
>close the dialogue letting you choose new or old setting , just close it using that "x " button
> then it will set up an virtual nexus 5
>then there will be two errors saying problem about "sdk" and "gradle "
> Caution : choose the appropriate sdk version by clicking on the link given by where the problem is shown .
> close android studio
> reopen android studio
> then you will be thrown a possible error with jdk not found .
>go to file -> project structure
> give the path to jdk , in my case its "usr/local/java/jdk..."
>close android studio and open again , the gradle might work well after this .

I had a similar problem with a library on github, which stated to install it as:
我在 github 上的一个库也遇到了类似的问题，它声明将其安装为：
dependencies {
compile 'com.github.chrisbanes.photoview:library:1.2.4'
}
This workaround seem to work, although it's suboptimal because it doesn't fetch a specific version and leads to Android Studio warnings:
这种解决方法似乎有效，尽管它不是最理想的，因为它不会获取特定版本并导致 Android Studio 警告：
dependencies {
compile 'com.github.chrisbanes.photoview:library:+'
}

Rather late but probably your gradle works in offline mode. Go to File->Settings->Gradle and uncheck the offline mode. Then try to refresh gradle and it should work
比较晚，但可能您的 gradle 可以在离线模式下工作。转到 File->Settings->Gradle 并取消选中离线模式。然后尝试刷新gradle，它应该可以工作

I am behind a corporate firewall. I had my http settings set, but not my https settings. So, I added the following to my gradle.properties file:
我在公司防火墙后面。我设置了 http 设置，但没有设置 https 设置。因此，我在 gradle.properties 文件中添加了以下内容：
systemProp.https.proxyPassword=...
systemProp.https.proxyHost=...
systemProp.https.nonProxyHosts=...
systemProp.https.proxyUser=...
systemProp.https.proxyPort=...

In my case I added this to my build.gradle (module:app):
就我而言，我将其添加到我的build.gradle (module:app) 中：
compile 'com.github.glomadrian:velocimeterlibrary:1.1@aar'
However, it gave me an error today. My solution is to use this instead:
但是，今天它给了我一个错误。我的解决方案是改用它：
compile 'com.github.glomadrian:velocimeterlibrary:+'

I have similar problem -> ERROR: Failed to resolve:
我有类似的问题 -> 错误：无法解决：
solved by using maven { url 'https://jitpack.io' }instead of

通过使用maven { url 'https://jitpack.io' }代替

}
It works fine.
