/**
 * Run integration tests using Surefire. This goal was copied from Maven's surefire plugin to accomodate a few things
 * for the NAR plugin:
 * <P>
 * 1. To test a jar file with its native module we can only run after the package phase, so we use the integration-test
 * phase.
 * </P>
 * <P>
 * 2. We need to set java.library.path to an AOL (architecture-os-linker) specific value, but AOL is only known in the
 * NAR plugin and thus cannot be set from the pom.
 * </P>
 * <P>
 * 3. To have the java.library.path definition picked up by java we need the "pertest" forkmode. To use this goal you
 * need to put the test sources in the regular test directories but disable the running of the tests by the
 * maven-surefire-plugin by setting maven.test.skip.exec to false in your pom.
 * </P>
