android - 无法在gradle中解析com.melnykov:floatingactionbutton:1.3.0

Question

如果我缺少明显的东西，我深表歉意，但是最近我将项目从Eclipse转换为Android Studio(和Gradle)，并尝试使用Melnykov's library添加对Floating Action Buttons的支持，但是Gradle无法解决它。我以为将compile 'com.melnykov:floatingactionbutton:1.3.0'添加到应用程序的build.gradle文件中很简单。我是否缺少某些内容，或者该资源无法下载或什么？提前谢谢。

我的应用程序的build.gradle文件:

apply plugin: 'android'

dependencies {
    compile 'com.android.support:support-v4:22.1.0'
    compile files('libs/opencsv-3.1.jar')
    compile 'com.android.support:appcompat-v7:22.1.0'
    compile 'com.melnykov:floatingactionbutton:1.3.0'
}

android {
    compileSdkVersion 22
    buildToolsVersion "22"

    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')
    }
}

我得到的错误是

Error:(6, 13) Failed to resolve: com.makovkastar:floatingactionbutton:1.3.0

您必须添加gradle应该从中下载aar的存储库。

repositories {
    jcenter()
}

如果没有这一部分，gradle不知道在哪里可以找到依赖项。

其他库不需要存储库，因为它们是本地jar(可以在lib文件夹中找到):

compile files('libs/opencsv-3.1.jar')

或本地专家(由sdk管理器提供)

  compile 'com.android.support:support-v4:22.1.0'
  compile 'com.android.support:appcompat-v7:22.1.0'
