Tomcat-users.xml is rewritten on container restart - how do I supply credentials? - maven

Question

Im using cargo to deploy a war file to a tomcat server. I'm unable to login to the manager however as conf/tomcat-users.xml is rewritten when I start the container ie
mvn cargo:run
how I can supply user/password creds to access the manager?
cheers!

Found it. You can supply custom configuration through the following xml (link to cargo docs in the above comments)
<files>
<copy>
<file>tomcat-users.xml</file>
<tofile>conf/tomcat-users.xml</tofile>
<configfile>true</configfile>
<overwrite>true</overwrite>
</copy>
</files>
So you can specify your own conf/*.xml or anything else and it will be copied before the container starts. I can login to the manager now :)
