OS: MacOS Monterey 12.7.6
JDK:java 21.0.4
MySQL on the MacOS:8.0.3

I followed your documention,started the DB server first,then create mysql plugin,start plugin,it's all goning well,but when I typed
mysql --no-beep -h 127.0.0.1 -P 3307 -u root(I changed 3306 to 3307 because the local mysql service owned port 3306), I could go into mysql terminal,but at that time , lealone server has error log,you can see pics below

step 2

step 3
