无法解决:android.arch.lifecycle:extensions:1.0.0-alpha1 android studio 3.0

Question

我正在android studio 3.0中使用android插件'com.android.tools.build:gradle:3.0.0-alpha1'和gradle版本构建一个项目gradle-4.0-milestone-1-all.zip.

二手maven repo:

maven {
            url 'https://maven.google.com'
      }

此外,在我的项目中使用android Room持久性和生命周期.已经在我的app gradle文件中声明了以下依赖项:

compile "android.arch.lifecycle:extensions:1.0.0-alpha1"
compile "android.arch.persistence.room:runtime:1.0.0-alpha1"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha1"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha1"

同步并构建项目时,它显示以下错误:

Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha1

我是否遗漏了这个问题或某些其他解决方案.

Answer 1

我通过更新我的app build.gradle文件解决了以下问题:

// 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:3.0.0-alpha2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

实际上必须从buildscript存储库中删除maven存储库并添加到allprojects存储库,如上所示.此外,您可以将maven存储库保留在两个位置,但必须包含在allprojects存储库中以解决问题.

Answer 2

添加应用程序/成绩文件

compile "android.arch.lifecycle:extensions:1.0.0-alpha4"
compile "android.arch.persistence.room:runtime:1.0.0-alpha4"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha4"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha4"

将Maven添加到基于项目的Gradle

allprojects {
repositories {
    jcenter()
    maven { url 'https://maven.google.com' }
}
}

容易编译
