Error creating a new MySQL database - create H2 instead

[mlavelle42]

I setup the overrides file with /opt/mango/ as root. See all three found below.
./overrides/classes/properties/env.properties
./templates/env.properties
./classes/env.properties

I then changed the /overrides/classes/properties/env.properties file as follows:

Commented out H2
#Default database settings, NOTE that on windows this must be an absolute path
#db.type=h2
#db.url=jdbc:h2:${ma.home}/databases/mah2
#db.location=${ma.home}/databases/mah2
#db.username=
#db.password=
#For web console
#db.web.start=false
#db.web.port=8091

Then uncommented MySQL
#MySQL database settings. Your MySQL instance must already be running and configured before this can be used.
db.type=mysql
db.url=jdbc:mysql://localhost/mango
db.username=validusername
db.password=validuserpassword

MySQL was running
/opt/mango/overrides/classes/properties $ /etc/init.d/mysql status
● mysql.service - LSB: Start and stop the mysql database server daemon

*But mango built an H2 database in /opt/mango/databases
7360512 Apr 22 15:20 mah2.h2.db

Note: the /opt/mango/classes/env.properties file is the original, and unchanged, set to create H2 by default.

Question: what did I do wrong?

To override the env.properties file place it in overrides/properties
