Maven Eclipse unit test configuration

I use Eclipse and for some of my unit tests, I need to set some JVM args for the test to work, -Djava.library.path in particular. I set it in my POM file as follows:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <argLine>-Djava.library.path=target/dll</argLine>
  </configuration>
</plugin>

and it works correctly when I build with Maven. However, when I run in Eclipse (even with the Maven plug-in installed - I have everything else in my Eclipse environment working properly with maven), this JVM argument is not applied. Does anyone know why this is or how to fix this?

Solution

Running the test in Eclipse with the JUnit test runner does not invoke maven , even if you are using m2eclipse.

I suggest you either:

create a maven launch configuration for the test goal;
add -Djava.library.path=target/dll to your JVM arguments in the JUnit launch configuration.
