Nant client error: System.IO.IOException: The file exists.

[caelevy]

After a recent server reboot, we just starting getting a strange error during our nant builds. Seems to be occurring during the VaultClientIntegrationLib.ServerOperations.SetRepository operation. The calling script is:

Code: Select all

	<vaultsetloginoptions user="${SGV.username}" password="${SGV.password}" URL="${SGV.url}" repository="${SGV.repository}" />
	<vaultgettolocationoutsideworkingfolder destPath="${basedir}\build">
	  <getoptions Merge="OverwriteWorkingCopy"  />
      <vaultfileset>
        <include name="$/build" />
      </vaultfileset>
    </vaultgettolocationoutsideworkingfolder>

Error received is:

Code: Select all

We can use the Vault client no problems, it's just the nant library that is no longer working. Server, client and library versions are 5.0.3.18802.

Is there a working folder set somewhere either in your script or using the Vault GUI client?

Can you login to a Vault GUI client on the same machine the scripts run on using the same user the scripts use?

Can you post any errors you see in your Vault Server Log that happened at the same time?

I just now saw your other post where you say:

Regular client (with the same credentials, from the same machine) work fine. Just this nant client is now not working. All components (nant client, regular client and server) are version 5.0.3.18802.

Still check that client to see if working folders are set.

I will remove the duplicate post.

Fixed by deleting files from the calling users \AppData\Local\Temp folder. We had over 70,000 files in there, and I guess the nant client was trying to assign a file name that was already extant.

Thanks for the quick response though.

Thank you for the update. I'm happy to hear about what you found.
