CruiseControl.NET : launch build on commit

Question

Hi all.

I searched a lot but i didn't find a solution for my problem.

I use CruiseControl.NET (1.4.4). My project (in ccnet.config) load a repository from a cvs server to a local repository, and launch some executables (msbuild, NUnit...).

I use a trigger (Interval or Schedule Trigger), that launch regularly my project. But if my project has not been modified, it always launch all next tasks. And I would like to avoid it. So i want to launch my project only if a commit has been detected.

Is there any solution for it please?

Thanks

Olivier

Answer 1

Your trigger needs to specify IfModificationExists:

<intervalTrigger 
    name = "dave" 
    seconds = "30"   
    buildCondition = "IfModificationExists" />

Although buildCondition="IfModificationExists" is the default anyway, so as long as its not set to ForceBuild you should be fine.

EDIT:

The URL Trigger might be of some use to you. You can set your svn server to modify a page on commmit and the CC.Net checks the page to see if it has changed, thus not getting all the files.

Answer 2

Just use IntervalTrigger, like this:

<triggers>
 <intervalTrigger />
</triggers>

You can also add an modificationDelaySeconds, to wait for a number of seconds before starting the build after the last commit.

    <modificationDelaySeconds>30</modificationDelaySeconds>

Thank you Anders Juul abd Andy for your quick answers.

By using the intervalTrigger with "IfModificationExists" build condition, the project must be loaded each time (it's logical ^^). But my project size is about 450Mo. So it's a little long. So my last question is : can we execute all builds and next tasks when a commit command has been detected? (without loading all files, in CruiseControl). I use TortoiseCVS (version 1.10.10). Maybe we can force CruiseControl project to be lauched after a commit?
