Gradle cannot build in IntelliJ due to it not finding the Forge files (apparently)

[EinSteini]

Hi there!

I've recently been starting out with mod programming in Minecraft. As a version i chose 1.16.5 and downloaded the appropriate Forge MDK. I followed the wiki and ran

gradlew genIntellijRuns

 

After that I tried to start the game and got the following error message in in the "Build Output" tab:

Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find net.minecraftforge:forge:1.16.5-36.1.4_mapped_official_1.16.5.
     Searched in the following locations:
       - https://files.minecraftforge.net/maven/net/minecraftforge/forge/1.16.5-36.1.4_mapped_official_1.16.5/forge-1.16.5-36.1.4_mapped_official_1.16.5.module

     Required by:
         project :

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

I unfortunately do not understand how to transfer the solutions from the "Possible Solutions" link to my own problem. It is also noticeable that in the ExampleMod class minecraft, minecraftforge.common, minecraftforge.event, minecraftforge.eventbus, minecraftforge.fml and apache.logging aren't found and therefore are red.

I hope I provided enough information for you to be able to give me a hint or to give me a solution to the problem. If anything is still needing for proper understanding, I will be determined to provide it.

Thanks in advance,

If you mean the entire console output, then here it is:

If you mean some different logs, then please guide me where to find them.

Changing the JDK worked!

Thank you very much
