> Add a ProjectArtifactsCache similar to PluginArtifactsCache

> Key: MNG-6025
> URL: https://issues.apache.org/jira/browse/MNG-6025
> Project: Maven
> Issue Type: Improvement
> Components: core
> Affects Versions: 3.3.9
> Reporter: Anton Tanasenko
> Assignee: Jason van Zyl
> Priority: Minor
> Fix For: 3.4.0
>
>
> Every mojo execution, if it specifies dependency resolution other than
> 'none', will cause a resolution to be performed.
> There is a guard in MojoExecutor's DependencyContext which guards against
> performing this resolution multiple times by looking at the changes to
> dependencyArtifacts list.
> However, during a build in an incremental/interactive environment, like
> eclipse m2e or maven console, those mojos might be executed at an arbitrary
> time and will not benefit from that DependencyContext check.
> I propose having a ProjectArtifactsCache (very similar to
> PluginArtifactsCache) that will cache artifact set as returned by
> LifecycleDependencyResolver#getDependencies().
> While it does not improve cli builds, incremental/interactive builds will
> receive a huge performance boost between pom changes.
> I've been able to get build of a project with a lot of dependencies (jenkins
> plugin) and a number of (fully incremental) mojo executions from 7 seconds to
> around 1.5 on a single java file change in eclipse m2e after introducing this
> cache.
> I will provide a patch shortly.
