如何检测会员在 JDA 中是否更改了其他会员的昵称？

Question

I want to make a Server Log feature, where stuff like messages changes, roles and nickname changes should be logged.

What I had done yet was this:

@Override
    public void onGuildMemberUpdateNickname(@NotNull GuildMemberUpdateNicknameEvent event) {
        if(BotMain.getInstance().getSettings().serverLogChannel != -1) {
            TextChannel serverlog = event.getGuild().getTextChannelById(BotMain.getInstance().getSettings().serverLogChannel);
            boolean removed = event.getNewNickname() == null;
            boolean created = event.getOldNickname() == null;
            EmbedBuilder builder = new EmbedBuilder();
            if(removed) {
                builder.setColor(Color.RED);
                builder.setAuthor("Nickname entfernt", event.getEntity().getUser().getAvatarUrl(), event.getEntity().getUser().getAvatarUrl());
                builder.addField("Änderung", event.getOldNickname() + " \u279C " + event.getEntity().getUser().getName(), false);
                builder.addField("Betrifft", event.getEntity().getAsMention(), false);
                builder.addField("Geändert von", event.getMember().getAsMention(), false);
            } else if(created) {
                builder.setColor(Color.GREEN);
                builder.setAuthor("Nickname erstellt", event.getEntity().getUser().getAvatarUrl(), event.getEntity().getUser().getAvatarUrl());
                builder.addField("Änderung", event.getEntity().getUser().getName() + " \u279C " + event.getNewNickname(), false);
                builder.addField("Betrifft", event.getEntity().getAsMention(), false);
                builder.addField("Geändert von", event.getMember().getAsMention(), false);
            } else {
                builder.setColor(Color.YELLOW);
                builder.setAuthor("Nickname geändert", event.getEntity().getUser().getAvatarUrl(), event.getEntity().getUser().getAvatarUrl());
                builder.addField("Änderung", event.getOldNickname() + " \u279C " + event.getNewNickname(), false);
                builder.addField("Betrifft", event.getEntity().getAsMention(), false);
                builder.addField("Geändert von", event.getMember().getAsMention(), false);
            }
            serverlog.sendMessage(builder.build()).queue();
        }
    }

But that's only triggered when a member changes his nickname, but not if a member changes the nickname of a other member.

Is there a possibility to detect this ?

You can take a look at this event GenericGuildMemberUpdateEvent ( GenericGuildMemberUpdateEvent ) and the following methods :

• getEntity() (to get the affected entity, the Member in your case)
• getMember() (to get the affector, the guy who changed the name, herited from GenericGuildMemberEvent )
• getPropertyIdentifier() (to get the property name, might be nickname or something)
• getNewValue() and getOldValue() (to get the old and new nickname)

I cannot verify this right now, keep me informed.
