---------------------------------------
Hi,
currently I'm using Windows 10 and VisualSutdioCode to run 'devcontainers' - I
have my java code on windows, and VSCode setup docker container with linux on
which I can develop and so on. This docker container has access to workspace on
Windows File System by mounted directory with mount type CIFS. During running
maven install I'm getting (only in java projects which use maven resources):
{code:java}
Caused by: java.io.IOException: Failed to copy full contents from <SRC> to
<DEST>
at org.codehaus.plexus.util.FileUtils.copyFile (FileUtils.java:1018)
at org.codehaus.plexus.util.FileUtils.copyFile (FileUtils.java:2234)
at org.apache.maven.shared.filtering.DefaultMavenFileFilter.copyFile
(DefaultMavenFileFilter.java:122){code}
So I assume that's connected to this issue. This problem makes it impossible to
use DevContainer at all. Is there any chance to fix this as [~seanpltr]

Thanks in advance for answer.

> Issue Type: Bug
> Components: Utilities
> Affects Versions: 2.5
> Environment: Win Server 2008, x86
> Reporter: Sean Poulter
> Priority: Major
>
> I've been struggling to troubleshoot intermittent {{IOExceptions}} thrown
> from {{FileUtils.doCopyFile}} when copying 2-4KB files from a local temporary
> file to a network drive. Despite the error, the file appears on the network
> drive when I check. Should the output channel/buffer be forced/flushed before
> closing, and synchronized before comparing the file lengths? It's a rather
> intermittent issue on a relatively high throughput PC so I'd expect there to
> be more IO latency than normal.
