I see one clarification to add to your "by value" explanation: what is imported is the dependencyManagement content from the *effective* imported model, ie with its interpolation (properties substitution) already done
I don't see how any property from the imported model could affect the importing model A few reference to source code: - the importer: https://maven.apache.org/ref/3.8.6/maven-model-builder/xref/org/apache/maven/model/composition/DefaultDependencyManagementImporter.html - and the effective model resolution that happens before: https://maven.apache.org/ref/3.8.6/maven-model-builder/xref/org/apache/maven/model/building/DefaultModelBuilder.html#L1236 Hope this helps Hervé On 2022/08/17 21:47:41 Laird Nelson wrote: > I have been using Maven for decades. > > I have a question about import scope. > > My mental model of this feature has always been the following: > > Suppose my project has: > > <dependencyManagement> > <dependencies> > <dependency> > <!-- coordinates --> > <type>*pom*</type> > <scope>*import*</scope> > </dependency> > </dependencies> > </dependencyManagement> > > My understanding is that the imported pom's <dependencyManagement> element > is effectively "copied over" this dependency "by value" and then the > resulting pom is interpreted afterward. > > Now consider an imported pom that defines a <properties> element.
