Replaced the error message with a newer similar one, with more details
- We are using Jenkins to run our system tests on a regular schedule. The Jenkins job downloads some python scripts from Perforce, runs them and compares the outputs with known-good results.
- The problem is, sometimes downloading from Perforce fails:
> 20:29:53 P4 Task: failed: java.io.IOException: Unable to delete file: c:\Jenkins\blahblah\...In the error message, P4 is a common abbreviation for Perforce. We have a [Jenkins plugin called P4](https://plugins.jenkins.io/p4/) which downloads files from Perforce; I guess it's this plugin that writes this error message. I think something is holding the file open, that's why it couldn't be deleted.- What can I do to prevent this? I imagine that it can be caused by an antivirus, some person quietly browsing in the Jenkins's file system, a random cosmic ray, etc. How can I even start investigating this?
- Did we do something fundamentally wrong in configuring our Jenkins job this way? Something which would completely prevent this issue from happening?

fixed an inaccuracy; removed unnecessary details
- We are using Jenkins to run our system tests on a regular schedule. The Jenkins job downloads some python scripts from Perforce, runs them and compares the outputs with known-good results.
To prevent confusion, the Jenkins job deletes all files from the target directory before downloading the scripts. The problem is, sometimes this fails:- > 20:29:53 P4 Task: failed: java.io.IOException: Unable to delete file: c:\Jenkins\blahblah\...

Jenkins failed to delete a file - why? How to prevent?
