Gradle无法解析外部依赖项。

Question

由于某种未知原因，Gradle 拒绝下载我在 gradle.build 文件中添加的每个依赖项。我正在尝试获取“me.dm7.barcodescanner:zbar:1.7”依赖项，但每次尝试同步 Gradle 时都会给我以下错误：

Error:(6, 13) Failed to resolve: me.dm7.barcodescanner:zbar:1.7

不仅是zbar库，而是每个不是com.android库的库。我不处于离线模式，所以那也不可能是原因。我的.build文件有什么问题吗？

apply plugin: 'com.android.application'

dependencies {
    compile fileTree(include: '*.jar', dir: 'libs')
    compile project(':MetaioSDK')
    compile 'com.android.support:support-v4:22.0.0'
    compile 'me.dm7.barcodescanner:zbar:1.7'
}

android {
    compileSdkVersion 19
    buildToolsVersion "21.1.0"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['../../templatesContent_crossplatform']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

Answer 1

好的，问题已经解决。在依赖项块中添加了以下内容：

repositories {
    mavenCentral()
}

实际上，存储库块更适合放在全局脚本范围内，而不是依赖项块内 - 在此处查找更多详细信息（http://gradle.org/docs/current/userguide/artifact_dependencies_tutorial.html）。 - Amnon Shochot

Answer 2

    buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.1'
    }
}
apply plugin: 'android'
repositories {
    mavenCentral()
}
dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'me.dm7.barcodescanner:zbar:1.7'
}

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

将仓库区块与其他区块独立放置
