Apache Maven is a build automation tool that addresses anyone who wants to build applications using Java. The idea behind the utility is to help make the design process overall smoother. It manages to achieve this due to the building process that entails describing how you intend to make the software solution and then specifying its dependencies.
We hope that we have created something that will make the day-to-day work of Java developers easier and generally help with the comprehension of any Java-based project.
At the same time, the application provides developers a uniform build system that relies on two main components, namely the Project Object Model (POM) and a set of plugins, which are shared by all projects that are built via this tool. Since the steps of developing an application follow the same pattern, you are likely to spend less time and effort when working on your next project.
Apache Maven is important to note that the application also includes helpful data that can be taken from your POM or that can be partially generated from the sources of your project. The direct advantage is that you can have the change log documents created directly from the source control as well as comprehensive unit test reports, dependency lists, mailing lists or cross-referenced sources.
Apache Maven Main Features
Maven is able to build any number of projects into predefined output types such as a JAR, WAR, or distribution based on metadata about the project, without the need to do any scripting in most cases.
Coherent site of project information:
Using the same metadata as for the build process, Maven is able to generate a web site or PDF including any documentation you care to add, and adds to that standard reports about the state of development of the project. Examples of this information can be seen at the bottom of the left-hand navigation of this site under the “Project Information” and “Project Reports” submenus.
Release management and distribution publication:
Without much additional configuration, Maven will integrate with your source control system and manage the release of a project based on a certain tag. It can also publish this to a distribution location for use by other projects. Maven is able to publish individual outputs such as a JAR, an archive including other dependencies and documentation, or as a source distribution.
Maven comes with a mechanism that your project’s clients can use to download any JARs required for building your project from a central JAR repository much like Perl’s CPAN. This allows users of Maven to reuse JARs across projects and encourages communication between projects to ensure that backward compatibility issues are dealt with.
Maven Other Features
- Simple project setup that follows best practices – get a new project or module started in seconds
- Consistent usage across all projects – means no ramp-up time for new developers coming onto a project
- Superior dependency management including automatic updating, dependency closures
- Able to easily work with multiple projects at the same time.
- A large and growing repository of libraries and metadata to use out of the box, and arrangements in place with the largest Open Source projects for real-time availability of their latest releases
- Extensible, with the ability to easily write plugins in Java or scripting languages
