I am attempting to set up Eclipse and Minecraft Forge with Gradle on Mac OS X so I can try my hand at modding. Whenever I run either of the following commands, Gradle returns the same error:
./gradlew genEclipseRuns ./gradlew setupDecompWorkspace
FAILURE: Build failed with an exception. * What went wrong: A problem occurred configuring root project 'forge-1.12.2-18.104.22.16854-mdk'. > Could not resolve all artifacts for configuration ':classpath'. > Could not resolve net.minecraftforge.gradle:ForgeGradle:3.+.

I’ve found a number of issues on the web that seem similar to this, namely this one, but I don’t really understand the answer. How can I get this to work? Thanks in advance for your feedback!
Some details that might be relevant:
I’m running java 1.8.0_65.
The Forge version is “forge-1.12.2-22.214.171.12454-mdk”, which is the recommended mdk for MC 1.12.2.
I’m using Gradle 6.4.1.
Thanks for your help! I seem to have found the problem.
For others who are wondering, changing the maven url from https to http in the repositories of forge’s build.gradle solved the error I posted above. However, I kept running into similar errors that seemed to be a result of forge no longer supporting 1.12.2. I deleted the old files and started over with 1.15.2, and now everything runs without issue.
