how to set system properties by using -D when running Scalatest in a Maven project

Question

I am new to Scala and Maven, we are starting to use Scalatest to do pre deployment tests for a Java project. We are using maven-scala-plugin to run the tests, and we want to read some parameters (properties) off the command line to run the test, for example:

mvn test -Dparam1=value1 -Dparam2=value

however the problem is that when we use System.getProperty("param1") in tests it gives back null, which should be value1.

Any advices will be appreciated!

I suspect this is because maven forks the process and creates a new JVM to run the tests in. You can disable forking by running it like mvn -DforkMode=never.
