Builds fail with '429 Too Many Requests' when resolving dependencies via Maven Central

Problem

Gradle builds are failing with the following message:

Could not GET 'package'. Received status code 429 from server: Too Many Requests

As a result, dependency resolution fails, blocking the execution of the builds entirely.

Cause

An introduction of stricter rate limits by Maven Central.

Resolution

Use a public mirror, such as from Google: https://docs.cloud.google.com/docs/buildpacks/java#hosted_maven_central_mirror

A gradle.settings file example that overrides the Gradle Plugin Management repository and the dependency repository:

pluginManagement {
    repositories {
        maven { url = uri("https://maven-central-eu.storage-download.googleapis.com/maven2/") }
        gradlePluginPortal()
        mavenCentral()
    }
}

dependencyResolutionManagement {
    repositories {
        maven { url = uri("https://maven-central-eu.storage-download.googleapis.com/maven2/") }
        mavenCentral()
    }
}
