从RxAndroid 1.x迁移到2.x(包括RxJava)

Question

我有一个运行RxAndroid 1.x的项目(Everythings works).我正在尝试迁移到2.x版本.

我的gradle文件:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile 'com.squareup.retrofit2:converter-gson:2.1.0'
    //compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    compile 'com.jakewharton:butterknife:8.4.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
    compile 'org.apache.commons:commons-lang3:3.4'
    compile('com.crashlytics.sdk.android:crashlytics:2.6.5@aar') {
        transitive = true;
    }

    //compile 'io.reactivex:rxandroid:1.2.1'
    //compile 'io.reactivex:rxjava:1.2.1'
    compile 'com.jakewharton.rxbinding:rxbinding:0.4.0'
    compile 'com.jakewharton.rxbinding:rxbinding-support-v4:0.4.0'

    compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'
    compile 'io.reactivex.rxjava2:rxjava:2.0.0'
    compile 'io.reactivex.rxjava2:rxandroid:2.0.0-RC1'
}

我有这个错误:

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties
    File1: /Users/agustin/.gradle/caches/modules-2/files-2.1/io.reactivex.rxjava2/rxjava/2.0.0/5151c737c01616c372c3d00ab145868ede10e826/rxjava-2.0.0.jar
    File2: /Users/agustin/.gradle/caches/modules-2/files-2.1/io.reactivex/rxjava/1.1.0/748f0546d5c3c27f1aef07270ffea0c45f0c42a4/rxjava-1.1.0.jar

为什么添加RxJava 1.1.0？

我可以排除rxjava.properties但我想了解错误.我已清理项目并使缓存无效,但错误仍然存​​在.

看图:

谢谢

只想跟进解决这个问题的方法.RxBinding 1.0.0已经发布,从这一点开始它应该与RxJava2兼容,但是它仍然会导入旧版本的RxJava,这导致了同样的问题.为了解决这个问题,只需将以下内容添加到android下的gradle构建脚本中即可.

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