Thank you all for your answers

I tried adding the following to my pom.xml

<properties>
  <database.driver>oracle.jdbc.OracleDriver</database.driver>
  <database.url>${database.url}</database.url>
  <database.username>${database.username}</database.username>
  <database.password>${database.password}</database.password>
</properties>

And tried reading with System.getProperty("database.username"), but it =
gave me null.

The reason for the ${database.url} and so on, is that it gets its values =
from either a default settings.xml or a user specific settings.xml, and =
that is how I need it to be. We are already using the sql-maven-plugin =
to bootstrap the database, but it only gets run once before all junit =
tests are run, and that is not what I need, I need it to run for every =
test to ensure a clean database.

I can easily make some code that drops my tables and so on, but I need =
the correct database properties from the correct settings.xml.

Bernd you talked about making a plugin that gets called before every =
test, how can I do this?

Sounds like this might help you:

- Create a Maven plugin which is executed in any phase >>bevore<< test,=20
e.g. 'generate-test-resources'. This will make it possible to set up the =

database. This plugin might help for starting the database (only if =
you're=20
using HSQL):=20
http://gforge.openehealth.org/gf/project/development/wiki/?pagename=3DDoc=
umentation+HSQLDB+plugin
, but there are others, too.

- Reading of POM-properties inside a Maven plugin is easy and described=20
here:=20

mojo-params.html#writing-plugins-sect-param-values

However, the scenario described by you clearly indicates that this is =

a unit test instead it is an integration test where other rules/plugins=20

restructuring of your project and might not be what you want.=20
