When working on a project, it is important to ensure that everyone on the team is using the same version of Apache Maven. This helps avoid problems that may arise between different Maven versions. An easy way to achieve this is to use Maven Wrapper.
What is a Maven wrapper?
Maven Wrapper is a tool that allows you to specify a specific Maven version for your project. It ensures that anyone who copies your project can build it using the exact same Maven version without having to manually install Maven.
How to set up the Maven wrapper
To set up Maven Wrapper for your project, follow these simple steps:
Open the terminal and navigate to the project directory.
Execute the following command to establish the Maven Wrapper configuration:
mvn wrapper:wrapper -Dmaven="3.9.9"
This command produces the necessary archives and the mvnw command, which downloads and executes Maven version 3.9.9.
Submit the resulting archive to a version control system (e.g., Git). This ensures that everyone who clones your project has access to Maven Wrapper.
Using the Maven wrapper
After setting up the Maven Wrapper, you can use it to execute Maven commands. Instead of using mvn, use ./mvnw (or mvnw.cmd on Windows). For example:
./mvnw clean install
This command will clean and build your project using the specified Maven version (3.9.9 in this example).
benefit
Using Maven Wrapper provides DevOps teams with several benefits:
consistency: Make sure all team members and CI/CD pipelines are using the same Maven version.
Easy to set up: New team members can get started quickly without having to worry about installing the correct Maven version.
Automation: Simplify the setup of the build environment, making it easier to build and deploy automation.
Did you know that Maven Wrapper can also help you manage different Maven versions for different projects? If you work on multiple projects that require different Maven versions, Maven Wrapper allows you to easily switch between them without any hassle.
