同一项目中的RxJava 1和RxJava 2 [英] RxJava 1 and RxJava 2 in the same project

问题描述

我们的项目使用RxJava 1:

Our project uses RxJava 1:

compile 'io.reactivex:rxjava:1.1.6'

我们使用一个内部使用RxJava 2的库:

There is a library we use that uses RxJava 2 internally:

compile 'io.reactivex.rxjava2:rxjava:2.0.9'

当我执行 ./gradlew assembleDebug 时，出现此错误:

When I do ./gradlew assembleDebug I get this error:

com.android.build.api.transform.TransformException:com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties
      File1: /Users/darklord/.gradle/caches/modules-2/files-2.1/io.reactivex/rxjava/1.1.6/2586312cd2b8a511e4c6236736f5a039fc0f2273/rxjava-1.1.6.jar
      File2: /Users/darklord/.gradle/caches/modules-2/files-2.1/io.reactivex.rxjava2/rxjava/2.0.9/a5aad74623ade11162dd53cdf0645a51b12221a0/rxjava-2.0.9.jar

我认为可以同时使用RxJava 1和RxJava 2，为什么我仍然遇到此错误?

I think it is said that RxJava 1 and RxJava 2 can be used at the same time, why I am still getting this error?

推荐答案

运行时不需要rxjava.properties文件.

rxjava.properties file is not required at run time.

因此，您可以在打包android应用时排除该文件，方法是在app/build.gradle文件中设置PackagingOptions，如下所示.

So you can exclude the file while packaging your android app by setting packagingOptions in app/build.gradle file as shown below.

android {
    ...
    packagingOptions {
        exclude 'META-INF/**rxjava.properties**'
    }
}
