Gradle正在搜索Ivy服务，但未定义Ivy配置/仓库。

Question

我从Gradle得到以下错误：

Could not resolve all dependencies for configuration ':unitTestCompile'.
> Could not find junit:junit:4.11.

这是我的build.gradle文件:

apply plugin: 'android-library'
buildscript {
    repositories {
        mavenCentral()
    }
dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}
version = '0.6.2'
configurations {
        unitTestCompile.extendsFrom runtime
        unitTestRuntime.extendsFrom unitTestCompile
}
dependencies {
    compile files('libs/android-support-v4.jar')
    unitTestCompile 'junit:junit:4.11'
}
android {
    buildToolsVersion "19.0.1"
    compileSdkVersion 17
sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src', 'bundled-src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
dependencies {
        compile fileTree(dir: './libs', include: 'Amplitude.jar')
    }
}
sourceSets {
        unitTest {
                java.srcDirs = ['tests/src']
                res.srcDirs = ['tests/res']
                assets.srcDirs = ['tests/assets']
                resources.srcDirs = ['tests/res']
        }
}
task doUnitTest(type:Test, dependsOn: assemble) {
        description = "run unit tests"
        testClassesDir = project.sourceSets.unitTest.output.classesDir
        classpath = project.sourceSets.unitTest.runtimeClasspath
}
check.dependsOn doUnitTest

调试运行结果表明它正在尝试使用Ivy而不是Maven解决依赖问题。

问题在于你只声明了一个用于构建脚本依赖项的存储库，但没有为常规依赖项声明任何存储库。（换句话说，你需要一个顶级 repositories 块。）此外，dependencies 块应始终位于 android 块之外，因为它是一个与 Android 插件无关的核心 Gradle 特性。
