Question

I have two surefire executions in one profile – they need different config.
When I run -Dtest=…, the matching test is running twice – once for each execution.

How can I make the test run only once?
Or better, how can I make surefire follow includes and excludes?
(One execution would run 0 tests; I’d use -DfailIfNoTest=false.)

This sounds like a misuse of the maven-surefire-plugin, cause you seemed to have some kind of integration-tests which should be done by the maven-failsafe-plugin instead. By using them you automatically have different configurations for unit- and integration tests. The maven-surefire-plugin is intended to run unit tests where as the maven-failsafe-plugin is intended to run integration tests. Furthermore you configuration looks like you need different kind of integration-tests which means in other word to have several integration-tests modules.

 +-- pom.xml
 +-- module-1
 +-- module-2
 +-- integration-test-single-node
 +-- integration-test-multi-node
 ...

And this will be the best thing to have different configurations for integration test runs.
