今天在使用RxJava2 和 Retrofit2在真机调试的时候出现如下错误：
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: C:\Users\Administrator.gradle\caches\modules-2\files-2.1\io.reactivex.rxjava2\rxjava\2.0.7\21734c0092a5d3c3ec99510e50c1ff76bdf0c65a\rxjava-2.0.7.jar

这是我的依赖：
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.squareup.okhttp3:okhttp:3.6.0'
compile 'io.reactivex.rxjava2:rxjava:2.0.7'

}
