I have a problem with maven dependencies. I try in my maven plugin to have a full dependencies graph, but some duplicated nodes does not appear.



My maven project is made of :



  • "dependency_test", the parent project of 4 modules

  • "mod1", "mod2", "mod3", "mod4", the child modules

  • "dependency_test_maven_plugin", the maven plugin project

here are the differents pom.xml files :

 try 
 DependencyNode rootNode = dependencyGraphBuilder.buildDependencyGraph(buildingRequest, artifactFilter);

 int level = 0;
 displayNode(rootNode, level);
 getLog().info("End depdendency graph");

 CollectingDependencyNodeVisitor visitor = new CollectingDependencyNodeVisitor();
 rootNode.accept(visitor);

 for (DependencyNode dependencyNode : visitor.getNodes())

On execution, the mojo traces are :



[INFO] --- dependency_test_maven_plugin:1.0.0:dependency-test-goal (default) @ mod1 ---
[INFO] Start depdendency graph
[INFO] mod1
[INFO] --mod2

[INFO] mod4
[INFO] End depdendency graph for node mod4
[INFO] Start depdendency graph for node mod3
[INFO] mod3
[INFO] End depdendency graph for node mod3


So, in the dependency graph traces like in visitor.getNodes traces, the dependency from mod2 to mod3 is not visible (I think it's because it's a duplicate of the link from mod1 to mod3).
Is there a way to have the complete trace :



mod1
--mod2
----mod3
----mod4
--mod3


Edit 1 : If I try to use dependency:tree on my parent project, I got the same result :

    Have you tried to run mvn dependency:tree command? It might help

  • Thanks for your answer, I edit the question with the dependency:tree result (same issue, unfortunally...)

    – Alexandre Nedjari

  • Did you try Maven dependency tree with output appended? It allows to aggregate the dependency trees of each module. mvn dependency:tree -DappendOutput -DoutputFile=/path/to/dependencyTree.txt

On execution, the mojo traces are :



[INFO] --- dependency_test_maven_plugin:1.0.0:dependency-test-goal (default) @ mod1 ---
[INFO] Start depdendency graph
[INFO] mod1
[INFO] --mod2
[INFO] ----mod4
[INFO] --mod3
[INFO] End depdendency graph
[INFO] Start depdendency graph for node mod1
[INFO] mod1
[INFO] --mod2
[INFO] ----mod4
[INFO] --mod3

[INFO] mod4
[INFO] End depdendency graph for node mod4
[INFO] Start depdendency graph for node mod3
[INFO] mod3
[INFO] End depdendency graph for node mod3


So, in the dependency graph traces like in visitor.getNodes traces, the dependency from mod2 to mod3 is not visible (I think it's because it's a duplicate of the link from mod1 to mod3).
Is there a way to have the complete trace :



mod1
--mod2
----mod3
----mod4
--mod3

    Have you tried to run mvn dependency:tree command? It might help

  • Thanks for your answer, I edit the question with the dependency:tree result (same issue, unfortunally...)

    – Alexandre Nedjari

  • Did you try Maven dependency tree with output appended? It allows to aggregate the dependency trees of each module. mvn dependency:tree -DappendOutput -DoutputFile=/path/to/dependencyTree.txt

I have a problem with maven dependencies. I try in my maven plugin to have a full dependencies graph, but some duplicated nodes does not appear.



My maven project is made of :



  • "dependency_test", the parent project of 4 modules

  • "mod1", "mod2", "mod3", "mod4", the child modules

  • "dependency_test_maven_plugin", the maven plugin project

here are the differents pom.xml files :

So, in the dependency graph traces like in visitor.getNodes traces, the dependency from mod2 to mod3 is not visible (I think it's because it's a duplicate of the link from mod1 to mod3).
Is there a way to have the complete trace :



mod1
--mod2
----mod3
----mod4

My dependency graph is so like :



mod1
--mod2
----mod3
----mod4
--mod3


I need to have this complete graph in my "dependency_test_maven_plugin" plugin. For now, it look like :

Mojo class :

@Mojo(name = "dependency-test-goal", defaultPhase = LifecyclePhase.PROCESS_RESOURCES, requiresDependencyCollection = ResolutionScope.COMPILE_PLUS_RUNTIME, requiresDependencyResolution = ResolutionScope.COMPILE_PLUS_RUNTIME)
public class JLinkMojo extends AbstractMojo 

 @Parameter(defaultValue = "$project", readonly = true, required = true)
 MavenProject project;

 @Parameter(defaultValue = "$session", readonly = true, required = true)
 private MavenSession session;

 @Component(hint = "default")
 private DependencyGraphBuilder dependencyGraphBuilder;

 ArtifactFilter artifactFilter;
 ProjectBuildingRequest buildingRequest;

 public void execute() throws MojoExecutionException 
 artifactFilter = new ExcludesArtifactFilter(Arrays.asList("com.aned:dependency_test_maven_plugin"));
 buildingRequest = new DefaultProjectBuildingRequest(session.getProjectBuildingRequest());

 buildingRequest.setProject(project);

 try 
 DependencyNode rootNode = dependencyGraphBuilder.buildDependencyGraph(buildingRequest, artifactFilter);
 getLog().info("Start depdendency graph");
 int level = 0;
 displayNode(rootNode, level);
 getLog().info("End depdendency graph");

 CollectingDependencyNodeVisitor visitor = new CollectingDependencyNodeVisitor();
 rootNode.accept(visitor);

 for (DependencyNode dependencyNode : visitor.getNodes()) 
 getLog().info("Start depdendency graph for node " + dependencyNode.getArtifact().getArtifactId());
 displayNode(dependencyNode, level);
 getLog().info("End depdendency graph for node " + dependencyNode.getArtifact().getArtifactId());
 

 catch (DependencyGraphBuilderException e) 
 throw new MojoExecutionException("Error", e);
 
 

 private void displayNode(DependencyNode rootNode, int level) 
 String indentation = "";
 for (int i = 0; i < level; i++) 
 indentation += "--";
 
 getLog().info(indentation + rootNode.getArtifact().getArtifactId());

 for (DependencyNode childrenNode : rootNode.getChildren()) 
 displayNode(childrenNode, level + 1);



On execution, the mojo traces are :



[INFO] --- dependency_test_maven_plugin:1.0.0:dependency-test-goal (default) @ mod1 ---
[INFO] Start depdendency graph
[INFO] mod1
[INFO] --mod2
[INFO] ----mod4
[INFO] --mod3
[INFO] End depdendency graph
[INFO] Start depdendency graph for node mod1
[INFO] mod1
[INFO] --mod2
[INFO] ----mod4
[INFO] --mod3
[INFO] End depdendency graph for node mod1
[INFO] Start depdendency graph for node mod2
[INFO] mod2
[INFO] --mod4
[INFO] End depdendency graph for node mod2
[INFO] Start depdendency graph for node mod4
[INFO] mod4
[INFO] End depdendency graph for node mod4
[INFO] Start depdendency graph for node mod3
[INFO] mod3
[INFO] End depdendency graph for node mod3


So, in the dependency graph traces like in visitor.getNodes traces, the dependency from mod2 to mod3 is not visible (I think it's because it's a duplicate of the link from mod1 to mod3).
Is there a way to have the complete trace :



mod1
--mod2
----mod3
----mod4
--mod3


Edit 1 : If I try to use dependency:tree on my parent project, I got the same result :

    Have you tried to run mvn dependency:tree command? It might help

  • Thanks for your answer, I edit the question with the dependency:tree result (same issue, unfortunally...)

  • Did you try Maven dependency tree with output appended? It allows to aggregate the dependency trees of each module. mvn dependency:tree -DappendOutput -DoutputFile=/path/to/dependencyTree.txt

What's happening: "mod3" resolves to the nearest parent.



I believe this falls under "dependency mediation" although that is more for version resolution.



To get the tree you expect you would have to buildDependencyGraph with the children as the root.
