Hi
I have this in my settings.xml
<settings>
<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<database.driver>oracle.jdbc.driver.OracleDriver</database.driver>
<database.url>jdbc:oracle:thin:@myhome:1521:orcl</database.url>
<database.username>foo</database.username>
<database.password>bar</database.password>
</properties>
</profile>
</profiles>
</settings>
And I have tried with these in my pom.xml:
<properties>
<db.driver>oracle.jdbc.OracleDriver</db.driver>
<db.url>${database.url}</db.url>
<db.username>${database.username}</db.username>
<db.password>${database.password}</db.password>
</properties>
And this:
<properties>
<database.driver>oracle.jdbc.OracleDriver</database.driver>
<database.url>dummy</database.url>
<database.username>dummy</database.username>
<database.password>dummy</database.password>
</properties>
I still get null with System.getProperty

It's as Anders wrote already. If you want to use the same property names in
settings.xml and pom.xml you have to put them in a profile, that's how I do it
and it works. The profile could be <activeByDefault> if you prefer.
So your settings.xml could look like this:
<settings>
<profiles>
<profile>
<id>someProf</id>
<activation>
<activeByDefault/>
</activation>
<properties>
<database.url>someUrl</database.url>
</properties>
</profile>
</profiles>
</settings>
And your pom.xml would be this:
<project>
...
<properties>
<database.url>someDummyValue</database.url>
</properties>
</project>
Now reading the properties via System.getProperty("database.url") shoud work.
