我刚刚在我的应用程序中使用Google Firebase云消息传递。
在使用FCM之前，我能够使用buildToolsVersion 23.0.2
因为我更新了buildToolsVersion 25.0.2并添加了一些firebase依赖项，所以我突然异常：
Warning: there were 1 unresolved references to library class members.
You probably need to update the library versions.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember)
Warning: Exception while processing task java.io.IOException: Please correct the above warnings first.
:app:transformClassesAndResourcesWithProguardForRelease FAILED
:app:transformClassesAndResourcesWithProguardForRelease (Thread[Task worker Thread 6,5,main]) completed. Took 4.354 secs.
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> Job failed, see logs for details
* Try:
Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.
BUILD FAILED
我需要为firebase添加proguard.txt吗？
我的Firebase依赖关系如下：
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'
此外我正在使用自定义解析SDK 引用此处https://github.com/ParsePlatform/Parse-SDK-Android/tree/master/Parse，我将解析sdk添加为外部项目，根据我的src代码稍作修改需要。
