Gradle找不到com.android.databinding:dataBinder:1.0-rc0

Question

我正在浏览https://developer.android.com/tools/data-binding/guide.html上的Android数据绑定指南.我已经确定我正在运行Android Studio 1.3(金丝雀版).

遵循指南,我收到此错误:

Gradle sync failed: could not find com.android.databinding:library:1.0-rc0

还有其他人有同样的问题吗？谢谢你的帮助.

Answer 1

我有这个问题并通过在我的顶级build.gradle中的allprojects.repositories下添加"jcenter"来解决它(我一直在使用mavenCentral).

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
        classpath 'com.android.databinding:dataBinder:1.0-rc1'
    }
}

allprojects {
    repositories {
        mavenCentral()
        jcenter() // <=== *** Adding this fixed it ***
    }
}

我在同步build.gradle文件时遇到错误.

错误:无法解析:com.android.databinding:library:1.0-rc0

错误:无法解析:com.android.databinding:adapters:1.0-rc0

我终于找到了解决方案.

dependencies {

    // instead of the below pathes...
    //classpath "com.android.tools.build:gradle:1.3.0-beta2"
    //classpath "com.android.databinding:dataBinder:1.0-rc0"

    // I used the following classpathes.... It works!
    classpath "com.android.tools.build:gradle:1.3.+"
    classpath "com.android.databinding:dataBinder:1.+"

}

通过查看您的错误,Gradle couldn't find com.android.databinding:dataBinder:1.0-rc0您应该尝试这样做,

classpath "com.android.databinding:dataBinder:1.0-rc1"

要使用,请DataBinding遵循所有这些步骤.

1. 更新您Android Studio的Android Studio 1.3版本.

2. 要设置您application的使用data binding,data binding请top-level build.gradle在"android"下面添加到文件的类路径.

   dependencies {
      classpath "com.android.tools.build:gradle:1.3"
      classpath "com.android.databinding:dataBinder:1.0-rc1"
   }
   

3. 然后确保jcenter位于顶级build.gradle文件中的项目的存储库列表中.

   allprojects {
      repositories {
          jcenter()
      }
   }
   

4. 在你想要使用数据绑定的每个模块中,在android插件之后立即应用插件.

   apply plugin: 'com.android.application'
   apply plugin: 'com.android.databinding'
   

5. Clean和build你的应用程序.

完整的代码

top-level build.gradle 文件,

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3'
        classpath "com.android.databinding:dataBinder:1.0-rc1"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

module-level build.gradle 文件,

apply plugin: 'com.android.application'
apply plugin: 'com.android.databinding'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.example.packagename"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.1'
}

请尝试将类路径更改为“com.android.tools.build:gradle:1.3.0-beta 2 ”并设置buildToolsVersion“ 23 rc2 ”。

执行此操作之前，请不要忘记通过 SDK 管理器更新 SDK 包。
