Example 1 with DependencyNodeVisitor

use of org.apache.maven.shared.dependency.graph.traversal.DependencyNodeVisitor in project maven-plugins by apache.

the class TreeMojo method serializeDependencyTree.

     * Serializes the specified dependency tree to a string.
     *
     * @param rootNode the dependency tree root node to serialize
     * @return the serialized dependency tree

    StringWriter writer = new StringWriter();
    DependencyNodeVisitor visitor = getSerializingDependencyNodeVisitor(writer);
    // TODO: remove the need for this when the serializer can calculate last nodes from visitor calls only
    visitor = new BuildingDependencyNodeVisitor(visitor);
