It would be preferred to use the build artifacts from the previous job instead of fetching the release file like this. The files attached on a release are not necessarily the same as builds from source code.

Tip: with curl the mv step is also completely unnecessary since you can also save the file as a specified filename

Suggested change

	RUN curl -LJO "https://github.com/jagrosh/MusicBot/releases/download/$MUSICBOT_VERSION/JMusicBot-$MUSICBOT_VERSION.jar" \
	&& mv "JMusicBot-$MUSICBOT_VERSION.jar" JMusicBot.jar
	RUN curl -o JMusicBot.jar -LJ "https://github.com/jagrosh/MusicBot/releases/download/$MUSICBOT_VERSION/JMusicBot-$MUSICBOT_VERSION.jar"
