Re: [tycho-user] run integration tests against multiple target platforms

maybe the maven-invoker-plugin [1] fits your bill? Normally, it builds
dedicated integration test projects in fresh reactors, but I think you
can shoehorn it into building the current project multiple times in
fresh reactors, each time with a different target platform set.
Previously compiled and installed projects could be re-used by setting
localRepositoryPath [2] accordingly. You just need to take care to stop
before the install phase (verify being the obvious choice), so that the
extra builds don't install stuff into your local repo.

I hope this helps as a first pointer to a solution that *might* work,
*if* you want a solution that's completely internal to Maven. If you can
afford to kick of multiple builds, why not do

  mvn clean install
  mvn clean verify -pl :your.test.project -DtargetPlaform=runtime1
  mvn clean verify -pl :your.test.project -DtargetPlaform=runtime2

This should avoid recompiling everything except for your.test.project at
least.

Hope this helps.

Andreas
