Fix BuildCommand.

This patch fixes two issues:
- On unix like platforms, after the clone of the repos, the maven
wrapper is not executable and the build command fails.
- The goal parameter of executeMavenWrapper was not used as the goal for
the maven InvocationRequest.

Changes:
* make maven wrapper executable before executing
* use the actual goal passed to executeMavenWrapper
