Cause

This error appears for Windows users running Bamboo 2.3.1 with the newer SVNKit 1.3 library. The file access problem is probably caused by a SVNKit bug with NTLM authentication, the real cause is unknown.

For further details see, this SVNKit bug report.

Resolution

Roll back SVNKit version, by following these steps:

1. Stop Bamboo and all remote agents;
2. Remove svnkit-1.3.0.5847.jar, jna-3.0.9.jar and trilead-ssh2-build213-svnkit-1.3-patch.jar from <bamboo-install>/webapp/WEB-INF/lib;
3. Replace with the 3 attached files;
4. Important: remove the complete Bamboo working copy in <bamboo-home>/xml-data/build-dir on the server and in <bamboo-agent-home>/xml-data/build-dir on remote agents. If you are using elastic agents with EBS snapshots you need to remove the working copy on the snapshot volume re-snapshot to remove the working copy permanently.
5. Restart Bamboo and remote agents.
