Can you timestamp each of the thread echo output to exclude the possibility the
output stream is representing order incorrectly?

Subject: ant:parallel is working differently in Maven than in Ant


I'm running the exact same set of tags with Ant and Maven, but I get different 
behavior. The Maven I'm using was built
from CVS on 11/25/03. I put this:

    <parallel>
      <sequential>
        <echo>Thread one sleeping for three seconds</echo>
        <sleep seconds="3"/>
        <echo>Thread one done sleeping</echo>
      </sequential>
      <sequential>
        <echo>Thread two sleeping for one second</echo>
        <sleep seconds="1"/>
        <echo>Thread two done sleeping</echo>
      </sequential>
    </parallel>
    <echo>All threads complete</echo>

in both a build.xml and maven.xml. Running ant on the target gives:

anttest:
     [echo] Thread one sleeping for three seconds
     [echo] Thread two sleeping for one second
     [echo] Thread two done sleeping
     [echo] Thread one done sleeping
     [echo] All threads complete

as I expected. Running Maven on the goal gives:

anttest:
    [echo] Thread one sleeping for three seconds
    [echo] Thread one done sleeping
    [echo] Thread two sleeping for one second
    [echo] Thread two done sleeping
    [echo] All threads complete

The two tasks run sequentially, even though they should run in the parallel. Running 
maven -X just gives a couple
messages about adding classpath references and verbose output on the sleep tag. Adding 
the "ant" namespace to all the
Ant tags results in the same behavior.

Has anyone else seen this? Is there something else I should or should not be doing to 
get the tasks to run in parallel
in Maven?
