Cannot build FML

Hello there and thanks for the report!
Currently, the build is broken, but I am planning to fix that. But this error shouldn't occur.
I deleted my users/x/.gradle directory, cloned this repository and ran gradlew build and it did fail, but, as I said, with a different error from yours that occurs way more late.
If you tried to upgrade the Gradle version (e. g. to Gradle 7), you might need to change
apply plugin: 'maven'
into
apply plugin: 'maven-publish'
in the build.gradle.

Otherwise, please try renaming/moving/deleting your users/x/.gradle and possibly also the users/x/.m2 directory and then running gradlew build again.

@quentin452 I have now updated the build.gradle on this repository to work out of the box again, might be worth it for you to give that a shot.
