------------------------------------
Summary: 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
Priority: Minor
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.
