Class DefaultDependencyManager

java.lang.Object

org.eclipse.aether.util.graph.manager.AbstractDependencyManager

org.eclipse.aether.util.graph.manager.DefaultDependencyManager

All Implemented Interfaces:

org.eclipse.aether.collection.DependencyManager

public final class DefaultDependencyManager
extends AbstractDependencyManager

A dependency manager that applies management at all levels with aggressive transitive behavior.

Overview

This manager provides the most aggressive dependency management approach, applying management rules at every level of the dependency graph. Unlike other managers, it starts applying management from the very first level (depth=0) and continues indefinitely.

Key Characteristics

• Aggressive Application: deriveUntil=Integer.MAX_VALUE, applyFrom=0
• First Level Management: Applies management even at the root level
• ModelBuilder Interference: Ignores and overrides ModelBuilder's work
• Complete Transitivity: Manages dependencies at all depths

When NOT to Use

⚠️ Warning: This manager is not recommended for Maven or Maven-like use cases because it interferes with ModelBuilder, potentially rewriting models that ModelBuilder has already processed correctly. This can lead to unexpected dependency resolution behavior.

When to Use

Consider this manager only for non-Maven scenarios where you need complete control over dependency management at all levels and are not using Maven's ModelBuilder.

Comparison with Other Managers

• ClassicDependencyManager: Maven 2.x compatibility, limited scope
• TransitiveDependencyManager: Proper transitive management, ModelBuilder-friendly
• This manager: Aggressive, all-level management (use with caution)

Since:

1.4.0

Constructor Detail

DefaultDependencyManager

public DefaultDependencyManager()

Creates a new dependency manager without any management information.

DefaultDependencyManager

public DefaultDependencyManager(org.eclipse.aether.scope.ScopeManager scopeManager)

Creates a new dependency manager with aggressive management behavior.

⚠️ Warning: This manager is not recommended for Maven use cases. It initializes with the most aggressive settings:

• deriveUntil = Integer.MAX_VALUE (always collect management rules)
• applyFrom = 0 (apply management from the very first level)
• No respect for ModelBuilder's work

Parameters:

scopeManager - application-specific scope manager for handling system dependencies, may be null to use legacy system dependency scope handling
