Hi I’m trying to create this mod but everytime I build it, this comes I don’t know what to do
Please never anywhere share screenshots of text if you only want to share the text and not something additional like colors or IDE annotations. Text in images is hard to read, especially on mobile, very hard to copy, and nearly impossible to search for.
Optimally, share Gradle problems by sharing a build --scan URL if possible.
Besides that, you also missed to provide almost all relevant information.
Select the highest node in the lower left tree so that you see the full output. (Don’t get fooled by https://youtrack.jetbrains.com/issue/IDEA-241844)
Anyway the part of the error message that is visible in your screenshots hints at some problem with something Minecraft-specific and so most probably this is not the right place to ask for.
