Support for passing a system property

[filiphr]

I would like to be able to pass a System property from the current execution to the new invocation.

Currently with @SystemProperty I can only provide a fix value.

Would you be interested in adding a new method (property) to SystemProperty and if it is set extract the value from that system property otherwise use the configured content. We are ready to work on this contribution to the project in case you are interested in this functionality.

The question is why do you need to pass a system property from the current execution to the integration test? Can you give a concrete example? Best would be a full working example...

We are using this extension to test different access policies to our artifacts. We create a pom.xml with a set of artifacts (same as our users will use), we then have a specific settings.xml (same as our users will use), this settings.xml needs access to a private repository, which means that we somehow need to pass the password property. We don't want to pass this password property as plain text in our source code, but we want to pass it through a secret as a system property to the test invocation.
