gradle从7.0.2降级到6.5 报错

gradle-wrapper.properties修改

前：distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-bin.zip
后：distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-bin.zip

报错 :

A problem occurred evaluating settings 'zDelete'.
> Could not find method dependencyResolutionManagement() for argument.....

原因：gradle 从6.8开始引入了，依赖解析管理。

删除settings.gradle 中 依赖解析管理相关的设置

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        谷歌()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }
}

报错：Minimum supported Gradle version is 7.0.2. Current version is 6.5.

原因：忘了改buil.gradle（project） 中的 classpath "com.android.tools.build:gradle:7.0.0"

改为  classpath "com.android.tools.build:gradle:4.1.3"

运行报错，发现各种依赖找不到。

: Task failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugNativeLibs'.

原因：没有设置依赖仓库添加

在buil.gradle（project）

allprojects {
    repositories {
        谷歌()
        mavenCentral()
    }
}

能运行了
