无法访问Maven的pom.xml中设置的属性，System.getProperty返回null

Question

I try to set up properties in my pom.xml and access them during my jUnit test. The class I want to read them in, is imported by the jUnit Test.java and is using String prop = System.getProperty("target1"); but it always is null. What I tried in my pom.xml already:

...
<profiles>
    <profile>
        <id>default</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <target1>2948</target1>
        </properties>
    </profile>
</profiles>

and also

...
<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-failsafe-plugin</artifactId>
   <version>2.15</version>
   <systemPropertyVariables>
      <target2>2948</target2>
   </systemPropertyVariables>
   <systemProperties>
     <property>
        <name>target3</name>
        <value>2948</value>
     </property>
   </systemProperties>
...
</configuration>
...     

I do have a parent pom.xml but that can't be the problem can it? I'm using Netbeans and starting the Tests by hiting "Test File" on the pom.xml

Thanks yous :)

I don't know about maven-failsafe-plugin, but I am able to get the result by adding property and value in maven-surefire-plugin since that is what is used by junit tests in a maven project. Here is a detailed explanation: Specify system property to Maven project

from the maven site ( http://maven.apache.org/surefire/maven-failsafe-plugin/ ) - "The Failsafe Plugin is designed to run integration tests while the Surefire Plugins is designed to run unit tests". Since you are running a junit, you should add your property to surefire plugin.
