android - Gradle 找不到库

Question

我正在使用 android studio。具有以下依赖关系。 Gradle 找不到第三方库 volley 和 square 但确实找到了 appcompat:

compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.mcxiaoke.volley:library:1.0.+@aar'
compile 'com.squareup.phrase:phrase:1.0.3'

.

Error:Failed to find: com.mcxiaoke.volley:library:1.0.+

我已经更新了 Android SDK 管理器工具和 Extras，包括支持库，但仍然没有成功。我已经尝试过使用 jcenter() 和 mavenCentral()。谁能帮忙？

build.gradle:

// 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:1.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
    dependencies{

    }
}

app/build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.tap"
        minSdkVersion 8
        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.mcxiaoke.volley:library:1.0.+@aar'
    compile 'com.squareup.phrase:phrase:1.0.3'
}

settings.gradle:

include ':app'

Answer 1

你需要从

compile 'com.mcxiaoke.volley:library:1.0.+@aar' 

到

 compile 'com.mcxiaoke.volley:library:1.0.+'

& 在存储库部分包含 mavenCentral()。 在您的 app/build.gradle 中，在发布部分之后的存储库部分添加 mavenCentral()。

Note - Google doesn’t provide a build of Volley for Gradle but there are mirrored copies of Volley published for use in Gradle.

参见 Unofficial mirror for android-volley library here .

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
    repositories {
        mavenCentral()
    }
}

并更改您的依赖项部分以使其看起来相似:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.mcxiaoke.volley:library:1.0.+'
compile 'com.squareup.phrase:phrase:1.0.3'
