Access properties of maven property plugin

Question

I included the maven property plugin like proposed in a response to this question Specify system property to Maven project. In order to be able to set my database properties from file (and override it with maven parameters in testing environment). However if I try to access one of the properties via System.getProperty("mysql.url") for example null is returned. How can I access the properties set from set properties goal.

private void initializeDatabaseConfiguration() {
    url = System.getProperty("mysql.url");
    con = DriverManager.getConnection(url, username, password);

}


   <plugin>
       <groupId>org.codehaus.mojo</groupId>
       <artifactId>properties-maven-plugin</artifactId>
       <version>1.0-alpha-2</version>
       <executions>
           <execution>
               <phase>initialize</phase>
               <goals>
                   <goal>set-system-properties</goal>
               </goals>
               <configuration>
                   <files>                          
                      <file>src/main/resources/config.properties</file>
                   </files>
                   <properties>
                       <property>
                           <name>mysql.url</name>
                           <value>${mysql.url}</value>
                       </property>
                   </properties>
               </configuration>
           </execution>
       </executions>
   </plugin>

Try to add phase:

<execution>
<phase>initialize</phase>
 <goals>
   <goal>set-system-properties</goal>
 </goals>

If you use the phase initialize, you can use the propriets after phase 'initialize'

This did not change anything – PKuhn Nov 12 '15 at 14:53
I want to use it in a method where a database connection is obtained like shown in the edited code – PKuhn Nov 12 '15 at 16:00
When you use this method initializeDatabaseConfiguration, if you use executable-jar whit main-class , you can use resources>filtering? – question_maven_com Nov 12 '15 at 16:15
could you give a more detailed answer how I would use resoure filtering to do this? – PKuhn Nov 16 '15 at 11:19
