Android studio未能找到：com。getbase:floatingactionbutton：1.3.0

Question

我正在尝试使用已经存在的android项目运行我的gradle文件。我在这个应用程序中遇到的唯一错误是未能找到：com.getbase： Floatingaction按钮：1.3.0。下面是我的gradle文件。是否需要更改才能使其正常工作？

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}

apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.android.support:appcompat-v7:21.+'
    compile 'com.google.android.gms:play-services:6.5.+'
    compile 'com.getbase:floatingactionbutton:1.3.0'
}

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    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')
    }
}

如果您需要更多信息，请告诉我。提前感谢您！

确保Android Studio中的“全局渐变设置”未设置为“脱机工作”

Answer 2

根据Maven Central在http://search.maven.org/#search|ga | 1 | floatingactionbutton表示库存在，所以我认为问题可能是您没有在构建脚本中添加存储库语句，以使其解决依赖关系；您在buildscript块中得到的只是解析构建系统插件，而不是构建依赖项。我知道这很令人困惑。在顶层添加此块：

repositories {
    mavenCentral()
}

我还假设您有一个具有平面目录结构和单个build.gradle文件的项目；当Android Studio通过向导创建项目时，它使用带有多个build.gradle文件的嵌套目录结构，并且它通常会在顶级构建文件中添加样板文件，这样您就不必将此repositories块添加到每个单独模块的构建文件中。如果是这种情况并且已经到位，那么这种补救措施将不起作用，因此您必须深入挖掘。
