问题背景

编译 react-native-image-crop-picker 报错：Could not find com.github.yalantis:ucrop:2.2.1-native

问题原因

缺少maven源

解决方案

vim /path/to/project/android/build.gradle，并行配置多个 maven 源：

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        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://jitpack.io" 
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }  
    }
}
