构建失败与Autact0锁在React本机Android

Question

我想与我的Android React本机应用程序使用Auth0锁。我也跟着安装说明here，但我在建筑出现以下错误：

FAILURE: Build failed with an exception. 

* What went wrong: 
A problem occurred configuring project ':app'. 
> Could not resolve all dependencies for configuration ':app:_debugCompile'. 
    > Could not find any matches for com.auth0.android:lock-react-native:+ as no versions of com.auth0.android:lock-react-native are available. 
    Searched in the following locations:

BUILD FAILED 

Total time: 16.332 secs 
Could not install the app on the device, read the error above for details. 
Make sure you have an Android emulator running or a device connected and have 
set up your Android development environment: 
https://facebook.github.io/react-native/docs/android-setup.html 

我注意到这些线：

file:/Users/m/git/this-or-that-app/node_modules/react-native/android/com/auth0/android/lock-react-native/maven-metadata.xml 
file:/Users/m/git/this-or-that-app/node_modules/react-native/android/com/auth0/android/lock-react-native/ 

我有一种预感，从本应安装在合适的位置是node_modules文件夹，但gradle在react-native-lock-android内部查看react-native模块时正在寻找内部。这可能是一个gradle配置的问题。有关如何解决此问题的任何提示？

原来，Auth0网站上react-native-android的文档已过时。使用github repo上的设置说明：https://github.com/auth0/react-native-lock-android。

但是，回购仍然有点过时，并没有完全清楚如何修改MainActivity.java。因此，对于稍后访问此帖的任何人，这里是我的MainActivity.java文件：

package com.thisorthatapp; 

import com.auth0.core.Strategies; 
import com.auth0.facebook.FacebookIdentityProvider; 
import com.auth0.lock.react.LockReactPackage; 
import com.facebook.react.ReactActivity; 
import com.facebook.react.ReactInstanceManager; 
import com.facebook.react.ReactPackage; 
import com.facebook.react.shell.MainReactPackage; 

import java.util.Arrays; 
import java.util.List; 

public class MainActivity extends ReactActivity { 

    /** 
    * Returns the name of the main component registered from JavaScript. 
    * This is used to schedule rendering of the component. 
    */ 
    @Override 
    protected String getMainComponentName() { 
     return "thisOrThatApp"; 
    } 

    /** 
    * Returns whether dev mode should be enabled. 
    * This enables e.g. the dev menu. 
    */ 
    @Override 
    protected boolean getUseDeveloperSupport() { 
     return BuildConfig.DEBUG; 
    } 

    /** 
    * A list of packages used by the app. If the app uses additional views 
    * or modules besides the default ones, add more packages here. 
    */ 
    @Override 
    protected List<ReactPackage> getPackages() { 
     LockReactPackage lockReactPackage = new LockReactPackage(); 
     lockReactPackage.addIdentityProvider(Strategies.Facebook, new FacebookIdentityProvider(this)); 
     return Arrays.<ReactPackage>asList(
      new MainReactPackage(), 
      lockReactPackage 
     ); 
    } 
}
