Hervé Boutemy created MNG-6575:
----------------------------------
Summary: make Dependency immutable
Key: MNG-6575
URL: https://issues.apache.org/jira/browse/MNG-6575
Project: Maven
Issue Type: Improvement
Components: Dependencies, Inheritance and Interpolation
Affects Versions: 3.6.0
Reporter: Hervé Boutemy
while working on Maven memory consumption issue MNG-6571, once VersionRange is
made immutable, memory used was divided by 2: the next big expected win is to
make Dependency immutable, which would probably once again divide memory by 2
because the vast majority of time, dependencies (be it in dependencyManagement
or base dependencies) are inherited without any modification
this will require to change
[ModelMerger|https://maven.apache.org/ref/3.6.0/maven-model/apidocs/org/apache/maven/model/merge/ModelMerger.html]
's {{mergeDependency(Dependency target, Dependency source, boolean
sourceDominant, Map<Object,Object> context)}} signature, since is not really an
immutable friendly signature
and also make [Dependency
code|https://maven.apache.org/ref/3.6.0/maven-model/apidocs/org/apache/maven/model/Dependency.html]
immutable (generated by Modello)
