Yes, but this example is just scaled down from where I first noticed
it. Originally instead of the simple sleeps and echos, I ran a message
feeder program that took 30-40 minutes to run. It was much more
obvious with that example that the programs ran sequentially. I just
created the simplified example for the post

Can you timestamp each of the thread echo output to exclude the possibility the

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
echoThread one sleeping for three seconds/echo
sleep seconds=3/
echoThread one done sleeping/echo
/sequential
sequential
echoThread two sleeping for one second/echo
sleep seconds=1/
echoThread two done sleeping/echo
/sequential
/parallel
echoAll 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?
