build.gradle中,我定义了一些3rd party库,所有这些库都可以在Maven Central中使用。

dependencies {
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'com.google.guava:guava:15.0'
    compile 'com.netflix.rxjava:rxjava-core:0.14.2'
    compile 'com.netflix.rxjava:rxjava-android:0.14.2'
}

(我们在libs下也有手动管理的jar(针对Eclipse用户),而我曾经使用这些
也使用compile fileTree(dir: 'libs', include: '*.jar')进行Gradle构建,但我正尝试从此过渡到更简单的自动化依赖管理。)

无论如何,由于某种原因获取deps失败:
* What went wrong:
A problem occurred configuring root project 'MyApp-Android'.
> Could not resolve all dependencies for configuration ':_debugCompile'.
   > Could not find com.google.code.gson:gson:2.2.4.
     Required by:
         :MyApp-Android:unspecified
   > Could not find com.google.guava:guava:15.0.
     Required by:
         :MyApp-Android:unspecified
   > Could not find com.netflix.rxjava:rxjava-core:0.14.2.
     Required by:
         :MyApp-Android:unspecified
   > Could not find com.netflix.rxjava:rxjava-android:0.14.2.
     Required by:
         :MyApp-Android:unspecified

我究竟做错了什么?

我在想我是否应该
repositories {
    mavenCentral()
}

...也位于构建文件的顶层(不仅在buildscript内部),但添加并没有帮助。

解析度

我太草率了; 在“无法解决依赖关系”方面为提供了帮助。之后,我遇到了编译错误,但这是由于实际上与上面的libs中的四个条目相比,代码(和dependendies中)具有更多的依赖关系。

因此,在我的情况下,我必须添加指向Maven Central的顶层repositories 加上,我们实际上拥有一些其他依赖项:
compile 'com.squareup.okhttp:okhttp:1.2.1'
compile 'com.android.support:support-v4:13.0.0'
compile 'com.android.support:support-v13:13.0.0'

(原始的,残破的)完整build.gradle:
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.1'
    }
}
apply plugin: 'android'

dependencies {
    // compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'com.google.guava:guava:15.0'
    compile 'com.netflix.rxjava:rxjava-core:0.14.2'
    compile 'com.netflix.rxjava:rxjava-android:0.14.2'
}

android {
    compileSdkVersion 19
    buildToolsVersion "19"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19
    }

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

        // 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')
    }

}

最佳答案

确实,您需要添加一个

repositories {
    mavenCentral()
}

build.gradle的顶层,以指定在哪里搜索依赖项。
