Thanks David,
This is what I was thinking.
Ruben:
Here is my sample config related to queue:
<queue name="Author" duplicates="UseFirst"/>
<project name="author" queue="Author" queuePriority="1">
<workingDirectory>G:\author\build\scripts</workingDirectory>
<artifactDirectory>G:\author\build\logs</artifactDirectory>
<modificationDelaySeconds>2</modificationDelaySeconds>
...
</project>
I could not see an option in the CCTray or webdashboard to post a
second build request (Forced Build) in the same project if already
building.
Regards,
Nikhil
