liuchangcheng created MNG-7551:
----------------------------------
Summary: Multithreaded building can create bad files for
downloaded artifacts in local repository
Key: MNG-7551
URL: https://issues.apache.org/jira/browse/MNG-7551
Project: Maven
Issue Type: Bug
Components: Artifacts and Repositories
Affects Versions: 3.8.6
Reporter: liuchangcheng
Assignee: Michael Osipov
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?
we are still facing this problem with maven 3.8.6
I get error like this below
