How to set a java system property during testing phase

Question

sorry for the dumb question, but I'm really new to maven and I cannot find any answer (I tried, I found something, but I did not understand it ;-) )

The problem is the following:

• I'm building my (eclipse) RCP APP using tycho
• My plugins rely on a system property to enable a debug mode (by default it is disabled, and it is enabled by launching the program with "-Ddebug=true" as java argument)
• I have some tests (packaged as fragment, as suggested everywhere)
• I want that the system property is set when my tests run

How can I instruct maven to do that?

Answer 1

try

<plugins>
  <plugin>
    <groupId>org.eclipse.tycho</groupId>
    <artifactId>tycho-surefire-plugin</artifactId>
    <version>${tycho-version}</version>
    <configuration>
      <systemProperties>
          <key>value</key>
      </systemProperties>
    </configuration>
  </plugin>
</plugins>
