Issue while migrating Gradle version from 6.5 to 7.0

Question

Could not resolve all dependencies for configuration ':debugRuntimeClasspath'. Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven5(http://download.flutter.io)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.0/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.

Answer 1

You either have to enable HTTPS for your custom repository or you have to change your repository definition to allow the insecure HTTP, like in the following example:

maven { url "http://[YOUR_REPOSITORY_URL]"; allowInsecureProtocol true }
