Hi, thanks for the pr Currently the build is failing because of a couple of errors while building

• in java, the classes need to be the same as the files they are in so either no sleep, or sleepless, not both.
• material.bed isn't a valid material in modern versions, instead there are ones with colours like RED_BED
