How to Install Apache Maven on Amazon Linux 2

What is Apache Maven?

Apache Maven is a build automation tool for Java projects. It is used to manage a project’s build, reporting, and documentation from a central piece of information. Maven uses a declarative approach to building control, in which the developer specifies what the desired outcome should be, rather than specifying the steps to achieve it. This allows Maven to handle much of the build process automatically, reducing the amount of work that the developer needs to do. Maven is based on the concept of a “project object model” (POM) and uses a set of plugins to execute tasks such as compiling code, running tests, and creating documentation.

Why Do People Use Apache Maven?

There are several reasons why people use Apache Maven:

1. Simplifies the build process: Maven automates the build process, taking care of the details of the build so that the developer can focus on coding.
2. Provides a uniform build system: Maven uses a standard directory layout and a standard build lifecycle, which makes it easier for developers to understand and work with projects built with Maven.
3. Manages dependencies: Maven can automatically download required dependencies and libraries that a project depends on, and manage the version conflicts that can arise when working with multiple dependencies.
4. Generates reports: Maven can generate reports on the project’s build, including information on the dependencies used, the testing results, and the project’s code quality.
5. Integrates with other tools: Maven can be integrated with other tools, such as continuous integration servers, making it easy to automate the build process and deploy code to production.

Overall, Maven helps to make the build process more efficient and reliable, allowing developers to focus on what they do best: writing code.
