Using insecure protocols with repositories, without explicit opt-in, has been deprecated. This is scheduled to be removed in Gradle 7.0. Switch Maven repository 'forge(http://files.minecraftforge.net/maven)' to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/6.8.3/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.
