Michael Osipov commented on MNG-7705:
-------------------------------------
[~cstamas], looking at:
{code:java}
public static NameMapper fileGav()
{
return new GAVNameMapper( true, "", ".lock", "", ".lock", "~" );
}
{code}
Locks for both metadata and artifact are identical, so I guess we can exclude
locking here, no?
{{NoSuchFileException}} maps to {{rename(2)}} with {{ENOENT}}:
{noformat}
[ENOENT] A component of the from path does not exist, or a path
prefix of to does not exist.
{noformat}
The exception message is misleading, I guess the target dir *does* exist, so is
the source (from) gone? The temp file, how can this be? We know that there no
concurrent write happens to the actual target file, but only to the temp then
the atomic move happens.

> On a CI server, we have multiple builds running on the same host and sharing
> the same repo.
> While testing 3.9.0, I started to see a NIO exception for the
> {{.lastUpdated}} file. This has worked fine for years, all the way up to
> 3.8.7.
> If you re-run the build, it will work. I think that it's just a collision
> between the different processes.
