Cannot create dev environment for forge 1.13 and above

Whenever I try to import a fresh project of Minecraft version 1.13 or higher, I seem to get multiple strange errors.

First of all when importing the project:

The above error is thrown multiple times for different classes.

The second error I get is as follows:

Could not find net.minecraftforge:forge:1.13.2-25.0.219_mapped_snapshot_20180921-1.13.

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

And the last error is more or less the same as the second but is as follows:

Could not find net.minecraftforge:forge:1.13.2-25.0.219_mapped_snapshot_20180921-1.13.

Note that this is a fresh project, I've followed the exact steps in the readme file and haven't yet changed anything in the build.gradle file. Changing the mappings does not resolve anything.
