How to prevent teamcity to collection changes from vcs root? Follow

Hi,

   I have some problems on teamcity's subversion checkout.

   The setting of my project'svcs root.

     I let teamcity to check out the source on agent side.

     Because the teamcity cant access vcs server directly.

     But teamcity still collections the changes of the vcs root before build run.

     So errors ocur!

   The picture above shows the teamcity collects the changes.I dont want it to happen.

   Maybe there are some hidden properties i dont know which cant do like this?
