Why does it not recognize builder()?
It wont show up and Im not sure why, please help.
It doesnt recognize these either. Please help.
for the first one, after I looked at the source code, there was no method: "DiscordMessage.builder()" it looks lilke he might have changed the way that it is used. I would try using "new DiscordMessageBuilder()" to get the builder but you should still see what the repo owner has to say. As for the ThumbnailEmbed... take a look at the class source code: https://github.com/MrPowerGamerBR/TemmieWebhook/blob/master/src/com/mrpowergamerbr/temmiewebhook/embed/ThumbnailEmbed.java I don't recognise the annotation "@AllArgsConstructor" but it suggests to me that you should use a constructor with each parameter being a field in that class ^ (I'd suggest in the same order)
I took your advice but it did this
But I think the whole thing is broken since when I loaded one of his classes it showed this

Do you have a discord server where we could talk directly?
To me this repo seems to have errors and incomplete code. You should try to get in contact with the repo author
There hasn't been any updates to this repo for over a month so I'd advise looking at the forks or making a fork yourself. I think the author has abandoned this.
Because he used a compiler plugin called lombok instead of writing it in standard java.
