Little problem to merge plugin 3.0 API to 4.0 API

In API 4.0 all the config code change ? beacause in eclipse i have to much red all in config andsome on command

What is your build.gradle (or pom.xml)?
Make sure your depending on API 4.0.1, as 4.0.0 doesn’t use dependencies right or something…

Edit:
Also, some things changed package

my pom.xml

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project LootCrate: Compilation failure
[ERROR] /C:/Users/maxime/git/Loot_case/Sponge/src/main/java/fr/terrainwax/LootCrate/MainLootCrate.java:[23,1] Plugin ID ‘LootCrate’ should match pattern a-z?
[ERROR] -> [Help 1]

Your plugin id needs to be all lower-case (e.g lootcrate).
