Sequential is a container task—it can contain other Apache Ant tasks. The
nested tasks are simply executed in sequence. Sequential's primary use is to support the sequential
execution of a subset of tasks within the parallel task
sequential task has no attributes and does not support any nested elements apart
from Ant tasks. Any valid Ant task may be embedded within the sequential task.
This example shows how the
sequential task is used to execute three tasks in
sequence, while another task is being executed in a separate thread.
<parallel> <wlrun ... > <sequential> <sleep seconds="30"/> <junit ... > <wlstop/> </sequential> </parallel>
