[FIXED] Allow insecure protocols, android gradle

Issue

I recently updated my android studio to Arctic Fox and got an error in my project

A problem occurred configuring root project 'so10'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Using insecure protocols with repositories, without explicit opt-in, is     unsupported. Switch Maven repository 
'maven3(http://oss.sonatype.org/content/repositories/snapshots)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols.
 See https://docs.gradle.org/7.0.2/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details. 

This is my gradle where the problem occurs

repositories {
    // maven { url 'https://maven.fabric.io/public' }
    maven { url "https://jitpack.io" }
    maven { url 'https://raw.github.com/Raizlabs/maven-releases/master/releases' }
    maven { url 'http://oss.sonatype.org/content/repositories/snapshots'}
    maven { url "https://plugins.gradle.org/m2/" }
    maven { url 'https://maven.google.com'  }
    google()
    mavenCentral()
    jcenter()
}

How do I solve it?

Solution

For insecure HTTP connections in Gradle 7+ versions, we need to specify a boolean allowInsecureProtocol as true to MavenArtifactRepository closure.
Since you have received this error for sonatype repository, you need to set the repositories as below:

1. Groovy DSL

repositories {
    maven {
        url "http://oss.sonatype.org/content/repositories/snapshots"
        allowInsecureProtocol = true
    }
    // other repositories ...
}

2. Kotlin DSL

repositories {
    maven {
        url = uri("http://oss.sonatype.org/content/repositories/snapshots")
        isAllowInsecureProtocol = true
    }
    // other repositories ...
}
