Bisser commented on MNG-5156: ----------------------------- Sorry, the whitespace got completely destroyed. I'm reposting it again: When calculating the scope of a dependency, Maven should assign to direct dependencies higher priority than transitive dependencies. For example: {noformat} com.acme:root:jar:1.0.0 +- com.acme:test-framework:jar:1.0.0:test <<<<<<<<<<<<< direct dependency \- com.acme:another-module:jar:1.0.0:compile \- com.acme:test-framework:jar:1.0.0:compile <<<<<<<<<<<<< transitive dependency {noformat} We can see that the 'root' project references test-framework directly with scope 'test'. However, the same test-framework also has a 'compile' scope, but via a transitive dependency. I believe that the final scope should be 'test' -- that's the explicit desire of the author of project 'root'. However, when I do roughly the following: {noformat} ProjectBuilder projectBuilder = plexusContainer.lookup(ProjectBuilder.class); ProjectBuildingRequest projectBuildingRequest = ....; projectBuildingRequest.setResolveDependencies(true); ... ProjectBuildingResult result = projectBuilder.build(pom, projectBuildingRequest); MavenProject proj = result.getProject(); ... Set<Artifact> artifacts = proj.getArtifacts(); {noformat} The 'test-framework' Artifact has a scope of 'compile'!!! (I will provide more code, if you'd like.) After some debugging to find out the reason for this, I reached class org.sonatype.aether.util.graph.transformer.JavaEffectiveScopeCalculator. There, in method chooseEffectiveScope, there's the following code: {noformat} else if ( scopes.contains( JavaScopes.COMPILE ) ) { effectiveScope = JavaScopes.COMPILE; } {noformat} So, no attention is paid whether the dependency is direct or transitive. If there's *any* dependency with scope 'compile', then the conflict is resolved by setting the final scope to 'compile'. But, as I said above, I believe the final scope should be 'test'. Here's a relevant stack trace for Maven 3.0.3: {noformat} JavaEffectiveScopeCalculator.chooseEffectiveScope(Set<String>) line: 220 JavaEffectiveScopeCalculator.resolve(ConflictGroup, Map<?,?>, Set<?>) line: 139 JavaEffectiveScopeCalculator.transformGraph(DependencyNode, DependencyGraphTransformationContext) line: 92 ChainedDependencyGraphTransformer.transformGraph(DependencyNode, DependencyGraphTransformationContext) line: 75 DefaultDependencyCollector.collectDependencies(RepositorySystemSession, CollectRequest) line: 253 DefaultRepositorySystem.collectDependencies(RepositorySystemSession, CollectRequest) line: 345 DefaultProjectDependenciesResolver.resolve(DependencyResolutionRequest) line: 131 DefaultProjectBuilder.build(File, ModelSource, DefaultProjectBuilder$InternalConfig) line: 166 DefaultProjectBuilder.build(ModelSource, ProjectBuildingRequest) line: 108 . . . {noformat} By the way, the Dependency Plugin reports this: {noformat} ... +- com.acme:test-framework:jar:1.0.0:test (scope not updated to compile) {noformat} The plugin resolves the conflict properly! The scope remains 'test', it's not set to 'compile'. I detected this problem with versions 3.0.3 and 3.0.2. It might be present in other versions too but I didn't bother to check any more versions. > org.sonatype.aether.util.graph.transformer.JavaEffectiveScopeCalculator > doesn't take into account direct vs. transitive dependencies > ------------------------------------------------------------------------------------------------------------------------------------ > > Key: MNG-5156 > URL: https://jira.codehaus.org/browse/MNG-5156 > Project: Maven 2 & 3 > Issue Type: Bug > Components: Dependencies > Affects Versions: 3.0.2, 3.0.3 > Environment: Irrelevant (I debugged the code and I provide an exact > location of the problem) > Reporter: Bisser > Priority: Minor > > When calculating the scope of a dependency, Maven should assign to direct > dependencies higher priority than transitive dependencies. > For example: > com.acme:root:jar:1.0.0 > +- com.acme:test-framework:jar:1.0.0:test <<<<<<<<<<<<< > direct dependency > \- com.acme:another-module:jar:1.0.0:compile > \- com.acme:test-framework:jar:1.0.0:compile <<<<<<<<<<<<< > transitive dependency > We can see that the 'root' project references test-framework directly with > scope 'test'.
