Summary of Changes

Hello @vogella, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates the Maven Wrapper into the project, which standardizes the Maven version used for builds across all development environments. It also refines the management of the Tycho build plugin version by moving its definition to a dedicated configuration file, promoting more consistent and efficient build processes.

Highlights

• Maven Wrapper Introduction: The Maven Wrapper (mvnw and mvnw.cmd) has been added to the project, allowing users to build the project without a pre-installed Maven instance, ensuring consistent build environments.
• Tycho Version Management: The Tycho build plugin version has been externalized from pom.xml and is now managed via .mvn/maven.config, setting it to 5.0.1.
• Build Configuration: A new .mvn/maven.config file has been introduced to define global Maven command-line options, including parallel build execution (-T4) and ignoring local Tycho artifacts (-Dtycho.localArtifacts=ignore).

Code Review

This pull request introduces the Maven wrapper, which is a great addition for ensuring consistent and reproducible builds across different environments. The changes correctly centralize the Tycho version configuration into .mvn/maven.config and also upgrade it from 5.0.0 to 5.0.1. I have one important security recommendation regarding the wrapper configuration to prevent potential supply chain attacks.

[gemini-code-assist]

For security, it's highly recommended to validate the downloaded Maven distribution against its checksum. This prevents potential man-in-the-middle attacks where an attacker could provide a malicious version of Maven. You can enable this by adding the distributionSha256Sum property with the SHA-256 checksum of the Maven distribution.

The checksum for Maven 3.9.11 is 43ae8433033359892621b19593539851a947d01435f042045936434453313262.
