Why does my spigot plugin maven build fail - cannot access org.bukkit.advancement.AdvancementDisplayType?

Question

I'm making a spigot plugin just for my minecraft server. Until now everything was OK and worked perfectly. Then I added some code and it just won't build... Here is the maven output:

https://pastebin.com/fftMVJth

And here is the code I added:

@EventHandler
public void onPlayerAdvancement(@NotNull PlayerAdvancementDoneEvent _event) {
    AdvancementDisplay $display = Objects.requireNonNull(_event.getAdvancement().getDisplay());
    String $message = "";
    
    switch ($display.getType()) {
        case TASK -> $message =
                """
                ["","<Name> has made the advancement ",{"text":"[<AName>]","color":"green","hoverEvent":{"action":"show_text","contents":[{"text":"<AName>\\n","color":"green"},{"text":"<ADescription>","color":"green"}]}}]
                """;
        case GOAL -> $message =
                """
                ["","<Name> has reached the goal ",{"text":"[<AName>]","color":"green","hoverEvent":{"action":"show_text","contents":[{"text":"<AName>\\n","color":"green"},{"text":"<ADescription>","color":"green"}]}}]
                """;
        case CHALLENGE -> $message =
                """
                ["","<Name> has completed the challenge ",{"text":"[<AName>]","color":"dark_purple","hoverEvent":{"action":"show_text","contents":[{"text":"<AName>\\n","color":"dark_purple"},{"text":"<ADescription>","color":"dark_purple"}]}}]
                """;
    }
    
    String final$message = $message;
    getServer().getOnlinePlayers().forEach(_player -> _player.sendRawMessage(final$message
            .replaceAll("<Name>", _event.getPlayer().getName())
            .replaceAll("<AName>", $display.getTitle())
            .replaceAll("<ADescription>", $display.getDescription())));
}

I don't think the error is in my code, it is probably in something else... So here is my pom.xml:

        </dependency>
    </dependencies>

</project>

I tried to bring the version in pom.xml down to 8, but then my code doesn't work, because I use string blocks, switch expressions and parametrized instanceof operators... But I don't think that would work then, because in the error message, some of the errors are from code that was there from start and worked perfectly before...

EDIT: I event tried to edit my code so it works on Java 8 (and bringing it down to that level too ofc), but the error is still there...

Thanks for help!
