Can't delete own message

Message toSend = new MessageBuilder().append("aa").build(); channel.sendMessage(toSend).queue(); message.delete().complete(); toSend.delete().queueAfter(5, TimeUnit.SECONDS);

The last line returns a NPE. at net.dv8tion.jda.core.entities.impl.MessageImpl.delete(MessageImpl.java:471)

You can’t delete messages from message builder, these messages have no ID assigned and thus cannot be modified or deleted. You need to use the response message from sendMessage:

channel.sendMessage(toSend).queue( message -> message.delete().queueAfter(5, TimeUnit.SECONDS) );

maybe you’re bot doesn’t have permissions for deleting message
