关于android：Gradle：不止一个项目变体：myLib与使用者属性匹配


Gradle: More than one variant of project :myLib matches the consumer attributes

我写的myLib库使用Firebase中的RemoteMessage，应用本身也使用Firebase。

使用gradle 4.7。在4.4.1。

中也面临此问题。

如何修复？

google-services gradle插件可与Google Play服务和Firebase 15+一起使用，但是您将其与版本12.0.1一起使用。

解决方案是：

  • 将您的Play服务和Firebase依赖项升级到版本15+(请注意，它们现在具有不同的版本)
  • 取消升级到3.3.0的操作，直到升级到3.3.0
    15+，即将gradle插件降级到版本3.2.1。

编辑1：有关在多模块应用程序中使用google-services 3.3的已知问题。这意味着降级到google-services到3.2.1可能是您唯一的选择，直到发布修复该错误的新版本为止。

编辑2：上述错误已在google-services gradle插件的4.0.1版本中修复！ (并且版本4.0.2也修复了在某些情况下发生的NPE)

顺便说一句，您应该转到FCM。
GCM将在不久的将来停止工作。

当我使用google-services：3.3.0时出现此错误。

在项目.gradle中降级到classpath 'com.google.gms:google-services:3.2.1'。

应该可以解决问题。

更新：在当前版本中可能不应该出现。

相关讨论

升级到3.3.1时遇到类似问题

通过降级到3.2.1修复了该问题

我们可以将Firebase版本> = 15与3.2.1一起使用

以下步骤对我有用---

  • 转到android / build.gradle文件。
  • 搜索jcentre()方法。
  • 将所有jcenter()方法移至其块内的底部。
    • 相关讨论

    过去几天我也遇到了类似的问题。

    implementation 'com.google.android.gms:play-services-auth:15.0.0'
    implementation 'com.google.firebase:firebase-messaging:15.0.0'

    解决方案是降级到

    2
    implementation 'com.google.android.gms:play-services-auth:12.0.1'
    implementation 'com.google.firebase:firebase-messaging:12.0.1'

    或考虑离开Goog??le Cloud Services并完全升级到FCM
