Gradle无法解析: commons-io:commons-io:+

Question

在Android studio中同步android项目和gradle时，无法解析如下截图所示的包。

​

​

这是我的build.gradle：

    buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}


android {
    compileSdkVersion 21
    buildToolsVersion "22.0.1"
    defaultConfig {
        applicationId "com.dmbteam.cityguide"
        minSdkVersion 10
        targetSdkVersion 22
        versionCode 4
        versionName '4.0'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'commons-io:commons-io:+'
    compile 'com.android.support:recyclerview-v7:+'
    compile 'com.android.support:cardview-v7:+'
    compile 'com.j256.ormlite:ormlite-android:4.48'
    compile('org.simpleframework:simple-xml:2.7.+') {
        exclude module: 'stax'
        exclude module: 'stax-api'
        exclude module: 'xpp3'
        exclude group: 'org.apache.commons', module: 'commons-io'
    }
    compile project(':pinterest_lib')
    compile('com.crashlytics.sdk.android:crashlytics:2.4.0@aar') {
        transitive = true;
    }
    compile 'com.google.android.gms:play-services-maps:7+'
    compile 'com.google.android.gms:play-services-location:7+'
    compile 'com.google.android.gms:play-services:7+'
}

Answer 1

在repositories下，我通常会发现我最终必须拥有一个类似于以下内容的链：

repositories {
        mavenLocal()
        maven { url 'https://maven.fabric.io/public' }
        jcenter()
}

换句话说，它首先尝试使用您本地的maven repo，然后是特定的maven repo/镜像，然后作为最后的手段退回到jcenter。
