Use something like this to update your tomcat users.

<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="manager-gui"/>

Tomcat users file is located inside conf folder of tomcat installation. To find the path of catalina_base you can use the command: ps aux | grep catalina You can find one of the values -Dcatalina.base=/usr/local/Cellar/tomcat/9.0.37/libexec

Most Important:

Don't forget to remove the comment lines from the tomcat-users.xml just before the start of the roles.

Follow my steps and be happy   1 - When you are configuring Netbeans for the first time  they will ask you for a  user  and  pass  for the Catalina-Server   2 - Type whatever  user  and  pass    This will modify your   tomcat-users xml  and will add   user password  MYPASS  roles  manager-script admin tomcat  username  MYUSER   3 - To use this  user  just restart your TOMCAT WEB SERVER and NETBEANS

When you re launching tomcat server from netbeans IDE you need to check in menu  tools- servers  on connection tab for tomcat server - there is catalina base directory  And you need to include something like     lt role rolename  manager   gt     lt user username  admin  password  admin  roles  manager   gt    at file    CATALINA BASE conf tomcat-users xml   or use username automatically generated by IDE with description already placed in this file or on connection tab  For Manager Apps   GUI access    lt role rolename  manager-gui   gt   lt user username  tomcat  password  s3cret  roles  manager-gui   gt
