从GCM迁移到FCM后，无法生成APK文件

Question

我刚刚将应用程序从GCM迁移到FCM，应用程序可以正常运行和调试，但在构建apk文件时，错误显示如下：

在APK res/layout/notification_action.xml中复制的重复文件文件1:D:\Plus Android\PlusMuse\build\jarjar\jar-20.jar文件2:D:\Plus Android\PlusMuse\build\jarjar\jar-21.jar

我搜索了任何网站和论坛，以找到解决方案，但仍然无能为力。我的依赖项：依赖项{编译文件树(包括：[*.jar']，目录：'libs'(

compile jarjar.repackage {
from 'com.google.firebase:firebase-messaging:17.3.3'
classDelete "com.google.android.gms.common.util.VisibleForTesting.class"
}
compile jarjar.repackage {
from 'com.google.firebase:firebase-appindexing:16.0.2'
classDelete "android.arch.lifecycle.LifecycleOwner.class"
}
compile project(':libs:com_actionbarsherlock')
compile project(':libs:holoEverywhereLib')
compile project(':libs:recoMediaLibrary')
compile project(':libs:preLollipopTransition')
compile project(':lyrimokit')
compile 'com.google.code.gson:gson:2.8.1'
compile 'com.android.support:multidex:1.0.1'
compile 'com.android.support:support-v4:26.0.+'
compile 'com.google.firebase:firebase-core:16.0.4'
compile 'com.google.firebase:firebase-messaging:17.3.3'
compile 'com.google.firebase:firebase-appindexing:16.0.2'
compile('com.crashlytics.sdk.android:crashlytics:2.5.5@aar') {
transitive = true
}

}应用插件："com.google.gms.googleservices">

我的包装选项

packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/license.txt'
exclude 'META-INF/NOTICE'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/notice.txt'
exclude 'META-INF/ASL2.0'
}

和

dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
classpath 'io.fabric.tools:gradle:1.+'
classpath 'com.google.gms:google-services:4.0.2'
classpath "org.anarres.jarjar:jarjar-gradle:1.0.0"
}

所以，有人能帮我找到解决方案吗？

转到android studio中的文件并执行无效缓存/重新启动。
