Sources for Minecraft libraries wont download after the latest intelij update.

[modmuss50]

The latest intelij update has broken downloading the sources of libraries hosted on Mojang's maven server. This is because Gradle/Intelij try to download the sources from the same maven repo that provided the library jar. Mojang does not rehost the -sources.jar.

Possible workarounds that loom can do:

• Download all sources, and not just sources for mods. Will be slower for the inital setup
• Move maven central above Mojang's maven

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

[modmuss50]

A workaround for this is to add maven central as an artifact url like so:

repositories.named("Mojang", MavenArtifactRepository) {
    artifactUrls ArtifactRepositoryContainer.MAVEN_CENTRAL_URL
}

Loom should do the same when registering the Mojang repo.
