Cruise control merging???

Question

Hi all, I had successfully extracted the compilation log present in my IDE into some one xml file very well.So inorder to merge it i had mentioned in my ccnet.config file inside the publisher task using the section.But when i force my build,i am able to get the output.xml file correctly but error comes in ccnet.config window that unable to merge as this file is currently used by some other process.please see below.

[VSAT:ERROR] Publisher threw exception: ThoughtWorks.CruiseControl.Core.CruiseC ontrolException: Unable to read the contents of the file: C: \ThreePartition\outp ut.xml ---> System.IO.IOException: The process cannot access the file 'C:\ThreeP artition\output.xml' because it is being used by another process. Can u please suggest me any method by which merging can be done successfully. I have pasted the whole ccnet.config file below.

Hi, I had just placed the publishers section below for the better view

           <publishers>
      <merge>
     <files>
              <file>C:\ThreePartition\output.xml</file>                 
         </files>
    </merge>
 <email from="[email protected]" mailhost="smtp.server.com" includeDetails="TRUE">
   <users>
          <user name="Maddy" group="buildmaster" address="[email protected]"/>
   </users>
   <groups>      <group name="buildmaster" notification="always"/>
     <group name="developers" notification="change"/>
   </groups>
 </email>

Some ideas:

• Eliminate other obvious applications that would be writing to that file: other CCNet projects, other CCNet instances (e.g. are you maybe running the service and something from the command line?), or perhaps your source control.
• If you're not attached to NAnt, try MSBuild and see if you get the same error. If all you're doing is compiling, you can pass the .sln or .csproj as a parameter directly to MSBuild.
• Make sure you're on the latest version of CCNet - they regularly publish what I would consider fairly major bug fixes regularly.
