Mickael Istria commented on MNG-7285:
-------------------------------------
PR at [https://github.com/apache/maven/pull/570] shows the regression. This
same test is working with maven 3.8.1 and starts failing since 3.8.3.
I think any mojo that uses project.getArtifacts() can get faulty result if
using parallel build.
> [Regression] MavenProject.getArtifacts() not returning correct value across

> --------------------------------------------------------------------------------------------
>
> Key: MNG-7285
> URL: https://issues.apache.org/jira/browse/MNG-7285
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.8.2, 3.8.3
> Reporter: Mickael Istria
> Priority: Critical
>
> Patch for MNG-6843 seems to cause that when trying to use
> MavenProject.getArtifacts() across different threads, some of them get an
> incorrect result.
> This cause an issue in m2e where we schedule a lot of work and don't have
> much control over which thread will do the work (there is a thread pool);
> we've faced several regressions because of this issue when trying to adopt
> 3.8.3 from 3.8.1. More details at
> [https://github.com/eclipse-m2e/m2e-core/pull/346|https://github.com/eclipse-m2e/m2e-core/pull/350]
> ,
> [https://github.com/eclipse-m2e/m2e-core/pull/347|https://github.com/eclipse-m2e/m2e-core/pull/350]
> and [https://github.com/eclipse-m2e/m2e-core/pull/350] .
> I'll try to capture it in a test case for maven repo in the next days.
