[1.16.3] Problem building recommended mdk

[Schmille 0]

I tried importing the recommended mdk version of Minecraft Forge 1.16.3 (1.16.3 - 34.1.0) into Intellij IDEA (version 2020.1.4) and got the following errors:

Could not make Minecraft POM. Missing version json

Could not find net.minecraft:client:1.16.3

 

A full stacktrace (gradlew build --stacktrace --plain-console) can be found here (pastebin)

Can anyone help with this?

OpenJ9 is not officially supported. Please use OpenJDK with HotSpot.

Please use OpenJDK with HotSpot.

I have switched to a JDK version which uses HotSpot. Unfortunately the errors are still there.

I managed to solve the issue. For anyone else who might be experiencing this problem, here is what I did:

I deleted the “forge_gradle” and “minecraft” cache-folders located under %USERPROFILE%\.gradle\caches and let IntellJ re-import the project.

Additionally (but likely unrelated) I updated to IntelliJ IDEA version 2020.2.3 and OpenJDK (Hotspot) version 1.8.0_272.
