Android Studio 2022.2.1项目迁移报错1、No variants found for ':app'. Check build files to ensure at least one variant exists. at:，2、manifest merger failed with multiple errors see logs，3、module java.base does not “opens java.io“ to unnamed module。

PS：（2022.2.1）新版AS。。。

1，JDK17  
2，AGP8.0，我仅更为7.1+

## 1，No variants found for ':app'. Check build files to ensure at least one variant exists. at: ##

## 网上解决方案 ##

Android SDK Build-tools版本不匹配，去AS的Settings下载自己需要的SDK相关配置，但对我不生效。

### 分享我的解决方法： ###

repositories {
            flatDir {
                dirs 'libs'
            }
    //        maven {
    //            url "http://dl.bintray.com/jlmd/maven"
    //        }
        }

### 2、manifest merger failed with multiple errors see logs ###

去Terminal输入以下命令查看具体Log

./gradlew processReleaseManifest --stacktrace

### 解决：除了清单文件添加属性之外，请检查项目以及Model和三方依赖SdkVersion版本尽量保持一致 ###

### 3、module java.base does not “opens java.io“ to unnamed module ###

1，添加以下代码

maven { url 'https://jitpack.io' }

2，升级自己的AGP版本。。即可解决

    distributionBase=GRADLE_USER_HOME
    distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-bin.zip
    distributionPath=wrapper/dists
    zipStorePath=wrapper/dists
    zipStoreBase=GRADLE_USER_HOME

classpath 'com.android.tools.build:gradle:7.1.2'

3，有些github拉取的项目依旧无法运行，尝试更改JDK来解决

4，有些项目可尝试升级 ext.kotlin\_version版本号

ext.kotlin_version = "1.6.10"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
