Android Studio编译程序报错 ?报错

Android Studio今天突然在编译项目的时候报错，以下是报错的信息：

 Information:Gradle tasks [:app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources, :easelibrary:generateDebugSources, :easelibrary:generateDebugAndroidTestSources, :easelibrary:mockableAndroidJar, :easelibrary:prepareDebugUnitTestDependencies, :easeui:generateDebugSources, :easeui:generateDebugAndroidTestSources, :easeui:mockableAndroidJar, :easeui:prepareDebugUnitTestDependencies, :http:generateDebugSources, :http:generateDebugAndroidTestSources, :http:mockableAndroidJar, :http:prepareDebugUnitTestDependencies, :more:generateDebugSources, :more:generateDebugAndroidTestSources, :more:mockableAndroidJar, :more:prepareDebugUnitTestDependencies]

 Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed with multiple errors, see logs

工程结构如下图：

build.gradle中的信息如下：其中主工程的targetSdkVersion是19，其他的是23.

有没有遇到此类问题的朋友，该如何解决呢？
