java - actionbarpull 的 gradle 文件有问题

Question

我有一些 build.gradle 文件

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.github.chrisbanes.actionbarpulltorefresh:library:+'
}

android {
    compileSdkVersion 18
    buildToolsVersion '18'

    defaultConfig {
        targetSdkVersion 18
    }

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

抛出这个错误:

A problem occurred configuring root project 'NewsFeeder'.
> Failed to notify project evaluation listener.
   > Could not resolve all dependencies for configuration ':_DebugCompile'.
      > Could not find any version that matches com.github.chrisbanes.actionbarpulltorefresh:library:+.
        Required by:
            :NewsFeeder:unspecified

但是，对 chrisbanes 的 actionbarpulltorefresh 的引用似乎是正确的:https://github.com/chrisbanes/ActionBar-PullToRefresh/wiki/QuickStart-Stock。怎么可能因为这个项目在 [maven central repo][1] 中可用？

有关信息，我在一些local.properties文件中设置了sdk.dir=/home/adt-bundle-mac-x86_64-20130522/sdk，这是与 echo $ANDROID_SDK 返回的相同

您需要告诉 gradle 它可以在哪里寻找依赖项。如果您希望 gradle 使用 mavenCentral 存储库，请将其添加到您的 build.gradle 文件中:

repositories {
    mavenCentral()
}

buildscript 存储库仅用于构建脚本依赖项，而不是项目依赖项。您想要在最外层或项目级别添加存储库条目。

您的 build.gradle 看起来像:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.github.chrisbanes.actionbarpulltorefresh:library:+'
}

android {
    compileSdkVersion 18
    buildToolsVersion '18'

    defaultConfig {
        targetSdkVersion 18
    }

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