【中文标题】react-native-pdf 库 gradle build 中的问题

【英文标题】：Issue in react-native-pdf library gradle build

【问题描述】：

我在运行react-native run-android 时收到以下构建错误

错误

无法解析所有配置文件 ':react-native-pdf:debugCompileClasspath'。 找不到 support-v4.aar (com.android.support:support-v4:26.1.0)。在以下搜索 地点： https://jcenter.bintray.com/com/android/support/support-v4/26.1.0/support-v4-26.1.0.aar

问题是由于 jcenter url 中的 404 错误。

/**
 * The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets

 * bundle directly from the development server. Below you can see all the possible configurations
 * and their defaults. If you decide to add a configuration block, make sure to add it before the

【问题讨论】：

你能显示项目“react-native-pdf”的build.gradle文件吗

谢谢纳库尔。但是我的 jcenter() 在 allprojects -> repositories 中的顺序不正确。我想通了并修复了。

【参考方案1】：

我自己想出来的。

allprojects 
    repositories 
        mavenLocal()
        google() // Jcenter must come after google() -- I only checked buildscript
        jcenter()
        configurations.all 
        resolutionStrategy 
            force 'com.facebook.android:facebook-android-sdk:4.22.1'
        
    
        maven 
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        
        maven 
            url "https://maven.google.com"
