M2E Core Tests

This repository contains the test suite for Eclipse M2E (Maven Integration for Eclipse), the Maven integration plugin for Eclipse IDE.

About This Repository

M2E Core Tests is a dedicated test repository that houses comprehensive integration and unit tests for the M2E project. These tests validate Maven project configuration, dependency resolution, lifecycle mapping, build integration, and other critical features of the Maven Eclipse plugin.

The test module (org.eclipse.m2e.tests) provides extensive coverage for:

• Maven project import and configuration
• Dependency management and resolution
• Build lifecycle execution
• Workspace synchronization
• JDT (Java Development Tools) integration
• Maven archetype support
• Plugin configuration and extensions
• Settings and preferences management

Repository History

This repository was forked from its historical location to the Eclipse M2E organization as part of organizational consolidation and IP review processes. The fork was created following the Eclipse Foundation IP Lab review documented in GitLab issue #19526.

Relationship to M2E Core

This repository is designed to work as a Maven module under the main m2e-core parent project. The pom.xml declares:

<parent>
  <groupId>org.eclipse.m2e</groupId>
  <artifactId>m2e-core</artifactId>
  <version>2.1.0-SNAPSHOT</version>
</parent>

While this repository can exist independently for test development and CI/CD purposes, it is intended to be built as part of the complete M2E build process.

Building

This project uses Maven with Tycho for building Eclipse plugins and tests:

mvn clean verify

The tests require:

• Java 21 or later
• Maven 3.6 or later
• Eclipse Tycho build infrastructure

License

Important: The license status of the files in this repository is currently unclear. Due to the historical nature of this forked repository, we have not been able to obtain clearance from all historic authors, and some files (including potential binaries) have not been fully vetted against the Eclipse IP process.

While we believe the content is covered under one or more open source licenses, we cannot definitively state that all files are licensed under the Eclipse Public License 2.0 (EPL-2.0). Users and contributors should be aware of this uncertainty when working with this repository.
