R – ccnet Not triggering build when changes are committed to svn

There is a problem with the ccnet. The server is not able to detect modifications even after the changes are committed to SVN. Can anyone help regarding this??

Below is the configuration file for the cruise:

Project
http://cruise01/ccnet

<sourcecontrol type="svn">
  <trunkUrl>http://svn01.com/abc/Project/trunk</trunkUrl>
  <workingDirectory>E:\Project\trunk</workingDirectory>
  <username>abc</username>
  <password>abcd</password>
  <timeout>36000000</timeout>
  <autoGetSource>true</autoGetSource>
  <tagOnSuccess>false</tagOnSuccess>
</sourcecontrol>

<tasks>
  <nant>
    <executable>E:\Project\trunk\tools\Nant\bin\NAnt.exe</executable>
    <buildFile>E:\Project\trunk\dev\build\Project.build</buildFile>
    <baseDirectory>E:\Project\trunk\dev\build</baseDirectory>
    <buildTimeoutSeconds>36000000</buildTimeoutSeconds>
    <logger>NAnt.Core.XmlLogger</logger>
    <targetList>
      <target>cruise</target>
    </targetList>
  </nant>
</tasks>
<publishers>
  <merge>
    <files>
      <file>E:\Project\trunk\dev\build\output\*.xml</file>
    </files>
  </merge>
  <xmllogger />
  <artifactcleanup cleanUpMethod="KeepLastXBuilds" cleanUpValue="100" />
</publishers>

The ccnet log is as follows :
