一、Cause: duplicate entry: META-INF/MANIFEST.MF

 

1、解决方案
在android studio编译ijkplayer时出现该问题：
Cause: duplicate entry: META-INF/MANIFEST.MF一般为 工程目录build:gradle文件 classpath 'com.android.tools.build:gradle:3.5.3'版本的原因。
可以把build:gradle的版本进行调整，网上有把3.5.2调成3.5.3的，偶把3.5.2调成3.4.2，结果成功编译运行。

二、

Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveEAndroid编译异常: duplicate entry: META-INF/MANIFEST.MF`或Entry name 'META-INF/MANIFEST.MF' collided

解决办法：

1.新版本AndroidStudio解决办法：（该方法不行就使用下面的旧版本方法试试）

注意：修改的是 项目的根目录下的settings.gradle文件内容

pluginManagement {repositories {gradlePluginPortal()google()mavenCentral()maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }maven { url "https://jitpack.io" }}
}
dependencyResolutionManagement {repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)repositories {google()mavenCentral()maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }maven { url "https://jitpack.io" }}
}
rootProject.name = "My Application"
include ':app'

2.旧版本AndroidStudio用下面的办法：

注意：修改的是 项目的根目录下的build.gradle文件内容

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {repositories {maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }jcenter()maven { url "https://jitpack.io" }}
}allprojects {repositories {maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }maven { url 'https://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }jcenter()maven { url "https://jitpack.io" }}
}
