ForceBuild concern with this scenario - CruiseControl.NET

Question

I have three projects in question, lets call them A, B and C. Where 'A' just prepares a cetain build scenario for B, which is the main build. C cleans up the scenario and basically resets B to its original state. I have set these projects in the same queue, and tested this process for the most part works excecpt when Project B fails. Here is the situation, which is explained below.

<project name="A" queue="main">
    <publishers>
     <email status of build/>
      <forcebuild>
        <project>B</project>
      </forcebuild>
      <forcebuild>
        <project>C</project>
      </forcebuild>
       </publishers>
   <task>Prepares special scenario</task>
 </project>
 <project name="B" queue="main">
   <publishers>
   </publishers>
    <task>Builds main project</task>
 </project>
 <project name="C" queue="main">
   <publishers>
   </publishers>
    <task>Resets special scenario</task>
 </project>

Scenarios:

1. When project 'A' is forced, it builds project B, if B is successful, it builds C. This works fine.
2. When project 'A' is forced, it builds project 'B', if B fails, it builds C. This is also fine in my case.
3. Now after number 2 scenario and bug are fixed in Project B; if project A is forced once more and project B displays a cruise status of 'fixed', it DOES NOT build C. This is NOT fine?

Can anyone see that reason why project C will not build if a combination of No.2 and No.3 is happens? Any help or direction is welcomed.

Thanks.

Answer 1

You should always clean up your test environment after you are done with it. I would recommend using the project trigger for project C and set it up something akin to the following. This will allow C to always run if A is successful (can be changed by modifying the project trigger in C).

<project name="A" queue="main">
    <publishers>
     <email status of build/>
     <forcebuild>
       <project>B</project>
     </forcebuild>
   </publishers>
   <tasks>Prepares special scenario</tasks>
 </project>

 <project name="B" queue="main">
 ...
 </project>

 <project name="C" queue="main">
   <triggers>
     <projectTrigger project="A" />
   </triggers>
   <publishers />
   <tasks>Resets special scenario</tasks>
 </project>

Can project A be responsible for cleaning up the current state and preparing for the new build.

Say for example there was a power failure part way through B's build. In this configuration you would need to manually force C to be able to run the build process?

If A runs the same tasks as C, then as own task, this would remove this problem and yours too I believe.
