Michael Osipov commented on MNG-7545:
-------------------------------------
Uprade to a test Java 8 version first. This one is years old.
> Multi building can create bad files for downloaded artifacts in local
> repository
> --------------------------------------------------------------------------------
>
> Key: MNG-7545
> URL: https://issues.apache.org/jira/browse/MNG-7545
> Project: Maven
> Issue Type: Bug
> Components: Artifacts and Repositories
> Affects Versions: 3.8.6
> Reporter: liuchangcheng
> Assignee: Michael Osipov
> Priority: Major
> Fix For: waiting-for-feedback

> Within a parallel build, modules A and B can start at the same time and
> decide at the same time that they need to download artifact X. Since X is not
> available locally, both can start download of X. Both will download X and
> both will try to write the file for X to disk.
> On Windows platforms, one of them can fail with file locking problems. On
> Unixes the contents of the written file can be non-deterministic.
> This issue is related to MNG-2802 in the sense that it can create a corrupted
> artifact file in the local repository, and it can happen to ANY file written.
> But as opposed to MNG-2802 the synhronization needed to fix this issue is
> basically only within a single running maven process, so regular java
> mechanisms can apply, whereas MNG-2802 probably needs to use a totally
> different solution space.

> is this issue fixed?
