Supported Upgrades

+ * + *

Model Version Upgrades

+ *
    + *
  • 4.0.0 → 4.1.0: Upgrades Maven 3.x POMs to Maven 4.1.0 format
    • + *
+ * + *

4.0.0 → 4.1.0 Upgrade Process

+ *
    + *
  1. Namespace Update: Changes namespace from Maven 4.0.0 to 4.1.0 for all elements
    2. + *
  2. Schema Location Update: Updates xsi:schemaLocation to Maven 4.1.0 XSD
    3. + *
  3. Module Conversion: Converts {@code } to {@code } and {@code } to {@code }
    4. + *
  4. Model Version Update: Updates {@code } to 4.1.0
    5. + *
+ * + *

Default Behavior

+ * If no specific options are provided, the tool applies {@code --fix-model} and {@code --plugins} by default to ensure Maven 4 compatibility. + * + *

All-in-One Option

+ * The {@code --all} option is a convenience flag equivalent to {@code --model 4.1.0 --infer --fix-model --plugins}. + * It performs a complete upgrade to Maven 4.1.0 with all optimizations, compatibility fixes, and plugin upgrades. + * + *

Maven 4 Compatibility Fixes

+ * When {@code --fix-model} option is enabled (or by default), applies fixes for Maven 4 compatibility issues: + *
    + *
  • Unsupported combine.children Attributes: Changes 'override' to 'merge' (Maven 4 only supports 'append' and 'merge')
    • + *
  • Unsupported combine.self Attributes: Changes 'append' to 'merge' (Maven 4 only supports 'override', 'merge', and 'remove')
    • + *
  • Duplicate Dependencies: Removes duplicate dependency declarations that Maven 4 strictly validates
    • + *
  • Duplicate Plugins: Removes duplicate plugin declarations that Maven 4 strictly validates
    • + *
  • Unsupported Repository Expressions: Comments out repositories with expressions not supported by Maven 4
    • + *
  • Incorrect Parent Relative Paths: Fixes parent.relativePath that point to non-existent POMs by searching the project structure
    • + *
  • .mvn Directory Creation: Creates .mvn directory in root when not upgrading to 4.1.0 to avoid root directory warnings
    • + *
+ * + *

Plugin Upgrades

+ * When {@code --plugins} option is enabled (or by default), upgrades plugins known to fail with Maven 4: + *
    + *
  • maven-exec-plugin: Upgrades to version 3.2.0 or higher
    • + *
  • maven-enforcer-plugin: Upgrades to version 3.0.0 or higher
    • + *
  • flatten-maven-plugin: Upgrades to version 1.2.7 or higher
    • + *
  • maven-shade-plugin: Upgrades to version 3.5.0 or higher
    • + *
  • maven-remote-resources-plugin: Upgrades to version 3.0.0 or higher
    • + *
+ * Plugin versions are upgraded in both {@code } and {@code } sections. + * If a plugin version is defined via a property, the property value is updated instead. + * + *

Inference Optimizations (Optional)

+ * When {@code --infer} option is enabled, applies inference optimizations to remove redundant information: + * + *

Limited Inference for 4.0.0 Models (Maven 3.x POMs)

+ *
    + *
  • Child GroupId Removal: Removes child {@code } when it matches parent groupId
    • + *
  • Child Version Removal: Removes child {@code } when it matches parent version
    • + *
+ * + *

Full Inference for 4.1.0+ Models

+ *
    + *
  • ModelVersion Removal: Removes {@code } element (inference enabled)
    • + *
  • Root Attribute: Adds {@code root="true"} attribute to root project
    • + *
  • Parent Element Trimming: + *
      + *
    • Removes parent {@code } when child has no explicit groupId
      • + *
    • Removes parent {@code } when child has no explicit version
      • + *
    • Removes parent {@code } when it can be inferred from relativePath
      • + *
    + *
    • + *
  • Managed Dependencies Cleanup: Removes managed dependencies pointing to project artifacts
    • + *
  • Dependency Inference: + *
      + *
    • Removes dependency {@code } when it points to a project artifact
      • + *
    • Removes dependency {@code } when it points to a project artifact
      • + *
    • Applies to main dependencies, profile dependencies, and plugin dependencies

+ * + *

Multi-Module Project Support

+ *
    + *
  • POM Discovery: Recursively discovers all POM files in the project structure
    • + *
  • GAV Resolution: Computes GroupId, ArtifactId, Version for all project artifacts with parent inheritance
    • + *
  • Cross-Module Inference: Uses knowledge of all project artifacts for intelligent inference decisions
    • + *
  • RelativePath Resolution: Resolves parent POMs via relativePath for artifactId inference
    • + *
+ * + *

Format Preservation

+ *
    + *
  • Whitespace Preservation: Maintains original formatting when removing elements
    • + *
  • Comment Preservation: Preserves XML comments and processing instructions
    • + *
  • Line Separator Handling: Uses system-appropriate line separators

This package contains the implementation of the Maven upgrade tool (mvnup) that helps + * upgrade Maven projects to be compatible with Maven 4. The tool is organized around + * a goal-based architecture with pluggable upgrade strategies.

+ * + *

Architecture Overview

+ * + *

Goals

+ *
    + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.Check} - Analyzes projects and reports needed upgrades
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.Apply} - Applies upgrades to project files
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.Help} - Displays usage information
    • + *
+ * + *

Upgrade Strategies

+ *

The tool uses a strategy pattern to handle different types of upgrades:

+ *
    + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.ModelUpgradeStrategy} - Upgrades POM model versions (4.0.0 → 4.1.0)
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.PluginUpgradeStrategy} - Upgrades plugin versions for Maven 4 compatibility
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.InferenceStrategy} - Applies Maven 4.1.0+ inference optimizations
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.CompatibilityFixStrategy} - Fixes Maven 4 compatibility issues
    • + *
+ * + *

Utility Classes

+ *
    + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.StrategyOrchestrator} - Coordinates strategy execution
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.PomDiscovery} - Discovers POM files in multi-module projects
    • + *
  • {@link org.apache.maven.cling.invoker.mvnup.goals.JDomUtils} - XML manipulation utilities
    • + *
+ * + *

Usage Examples

+ * + *

Check for Available Upgrades

+ * 
{@code
+ * mvnup check
+ * }
+ * + *

Apply All Upgrades

+ * 
{@code
+ * mvnup apply --all
+ * }
+ * + *

Upgrade to Maven 4.1.0 with Inference

+ * 
{@code
+ * mvnup apply --model 4.1.0 --infer
+ * }
+ * + *

Extension Points

+ * + *

To add new upgrade strategies:

+ *
    + *
  1. Implement {@link org.apache.maven.cling.invoker.mvnup.goals.UpgradeStrategy}
    2. + *
  2. Optionally extend {@link org.apache.maven.cling.invoker.mvnup.goals.AbstractUpgradeStrategy}
    3. + *
  3. Annotate with {@code @Named} and {@code @Singleton}
    4. + *
  4. Use {@code @Priority} to control execution order
    5. + *
+ * + * @since 4.0.0 + */ +package org.apache.maven.cling.invoker.mvnup.goals; diff --git a/impl/maven-cli/src/main/java/org/apache/maven/cling/invoker/mvnup/package-info.java b/impl/maven-cli/src/main/java/org/apache/maven/cling/invoker/mvnup/package-info.java new file mode 100644 index 000000000000..b2d580c97723 --- /dev/null +++ b/impl/maven-cli/src/main/java/org/apache/maven/cling/invoker/mvnup/package-info.java @@ -0,0 +1,28 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
