Here is a downloadable sample that demonstrates the concept in more detail. To access the Central Repository with Gradle via HTTPS you can define a Maven repository specifying the URL. Gradle supports a wide range of sources for dependencies, both in terms of format and in terms of connectivity. These can be declared as local repositories, using a local filesystem path to access them. To restore this behavior, for example, for Maven central you can use mavenCentral { metadataSources { mavenPom(); artifact() } }. Ivy repository with authentication, Example 15. As Gradle prefers to use modules whose descriptor has been created from real meta-data rather than being generated, flat directory repositories cannot be used to override artifacts with real meta-data from other repositories declared in the build. This repository does not need any configuration to be made just make sure that your IDE/machine is connected to the internet to download and use the dependencies from the central repository. The Central Repository is the default repository for Apache Maven, SBT and other build systems and can be easily used from Apache Ant/Ivy, Gradle and many other tools. with AWS V4 authentication.
