我的Android Studio Gradle无法从Maven Central获取插件

Question

I tried to add smoothprogressbar library to my android project

I added these lines to my build.gradle

dependencies {
    // of course, do not write x.x.x but the version number
    compile 'com.github.castorflex.smoothprogressbar:library:0.5.2'
}

And when i sync the gradle its saying that Failed to find : com.github.castorflex.smoothprogressbar:library:0.5.1

I tried putting mavenCentral() and maven url in build.gradle and other solutions which i found in stackoverflow but nothing seems to work.

Edited :

This is my full gradle file

apply plugin: 'com.android.application'


repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    //compile 'com.android.support:cardview-v7:21.+'
    compile('com.google.http-client:google-http-client-android:1.18.0-rc') {
        exclude(group: 'com.google.android', module: 'android')
        exclude(group: 'org.apache.httpcomponents', module: 'httpclient')
    }
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile project(path: ':backend', configuration: 'android-endpoints')
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile project(':library')
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile 'com.android.support:support-v4:19.+'
    compile 'com.google.android.gms:play-services:4.4.52'
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile 'com.android.support:support-v13:19.+'
    compile 'com.google.code.gson:gson:2.+'
    compile 'com.github.castorflex.smoothprogressbar:library:0.5.2'
}

android {
    signingConfigs {
        ...
    }
    compileSdkVersion 19
    buildToolsVersion '20.0.0'
    defaultConfig {
        applicationId ...
        minSdkVersion 15
        targetSdkVersion 19
        versionCode 1
        versionName '1.0'
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.config
        }
    }
    dexOptions {
        preDexLibraries = false
    }
    productFlavors {
    }
}

Answer 1

Works for me. You should post more of your build.gradle script (in particular, how exactly you tried to put mavenCentral() in the script), but the gist is that you need the following outside of the android {} block in the script (and this is in addition to the similar code in the buildscript {} block):

buildscript {
    // ...
}

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.github.castorflex.smoothprogressbar:library:0.5.2'
}

android {
    // ...
}

Then re-sync your project with Gradle.

使用此方法：

compile 'com.github.castorflex.smoothprogressbar:library:0.5.2@aar'
