The author of this book is a passionate freelance programmer with 8 years of experience in the industry. The book also provides basic information about Apache Maven and how to use it for the implementation of software engineering in any project. Maven: The Complete Reference Although Maven is one of the most popular building tools for software, there is no single book which provides complete information and serves as both an introduction and authoritative reference. The book has been written by a team of expert authors.
Maven By Example This Maven ebook offers an introduction to Maven software such as how it can be used to build required automation. Chapters on how to install Maven, a step by step guide on creating simple Maven projects, and also chapters for advanced users such as multi-module Enterprise Project handling make this book a must-have for Maven enthusiasts. It also provides a thorough introduction to Apache Maven as well as the functioning and creation of various simple web applications and projects for the developers.
It doesn't contain any sub-modules for now. You can pick archetype number , maven-archetype-quickstart, which generates a basic Java project.
The archetype:generate command also requires you to fill in the Apache Maven project co-ordinates including the project groupId, artifactId, package, and version. After project generation, inspect the POM file of the original parent project. You will find the following block added: moduleJar The sub-module we created has been automatically added in the parent POM.
It simply works—no intervention required! Compiling and installing both sub-modules in the correct order in case sub-modules are interdependent is essential. In Multi-modular projects, where dependencies can run into tens or even hundreds, Apache Maven excels in allowing you to retain a high degree of control and stability.
Apache Maven dependencies are transient, which means Maven will automatically discover artifacts that your dependencies require. This feature has been available since Maven 2, and it especially comes in handy for many of the open source project dependencies we have in today's enterprise projects. Getting ready Maven dependencies have six possible scopes: ff Compile: This is the default scope.
Compile dependencies are available in the classpaths. While we take a closer look at these in the How it works Most Apache Maven projects have dependencies to other artifacts that is, other projects, libraries, and tools. Management of dependencies and their seamless integration is one of Apache Maven's strongest features. These dependencies for a Maven project are specified in the project's POM file.
Having a single source for all dependency definitions makes dependency versioning simpler, thus keeping large projects' dependencies organized and manageable over time. The parent POM would contain the complete definition of the dependency: mysql mysql-connector-java 5. The dependencies scope and type are defaulted to compile and JAR. However, they can be overridden as required: junit junit 4.
System dependencies are not looked for in the repository. For them, we need to specify the path to the JAR: sun. After that, it should be the responsibility of Apache Maven to take care of including all dependencies. System dependencies would force the developer to take extra steps and that dilutes the effectiveness of Apache Maven in your team environment.
In the real world, you and your team can, at best, agree upon a set of programming standards and implement automated source code quality checks into your project build to verify that a certain level of code quality is upheld. These automated source code quality checks and verifications still cannot ensure that the application itself is designed correctly.
However, it can help some of the lesser experienced programmers adhere to standards expected of them. In a typical configuration, the build fails if PMD detects quality issues in the source. The following steps need to be taken to integrate source code quality checks into your Apache Maven project's build cycle.
If you don't have an Apache Maven Java project, create one by running the following goal: mvn archetype:generate Launch the project's POM file in a text editor for editing. The PMD plugin needs to be integrated into your project. It can be added to the project POM file under the reporting element: org.
Here's an optional step: if you wish to use a custom set of rules and configuration for code-quality checks, it can be done by adding a configuration block to the plugin declaration. Have a look at the following code: org. PMD is an open source tool that scans Java code and generates code quality reports. The reports are generated based on identification of potential bugs, dead code, non-optimized code, duplicate code, and so on.
Does the code meet quality guidelines? Good code committed to repository Poor code? Build fails. As we just saw, there are two ways to invoke PMD's code quality checks. You could either do it manually or automatically.
In the first case, the individual developer would be responsible for executing code quality check each time a change is made. This approach needlessly adds another task for the already busy programmer.
It makes more sense to follow the second approach for full automation. Source code quality checks are most beneficial when they are fully integrated with your build automation and continuous integration processes. Whenever a build is run on the developer's machine, Apache Maven automatically executes the PMD plugin.
If the new code fails to meet the code quality standards, the build should fail and the team must be automatically notified. Test Driven Development or TDD, as it's more commonly known, introduces very short, iterative development cycles wherein the programmer first writes a failing test case, then builds the functionality followed by code refactoring, if required.
Mention the dependency in your POM: junit junit 4.
However, this archetype may include an older version of JUnit 3. You need to edit your POM file and revise the dependency version to 4. Create your first test case for an existing class using your IDE. Test; import static org. If you need to merge several test cases, they can be combined into a test suite: package net. RunWith; import org. Suite; RunWith Suite.

You should see something similar to: T E S T S Running net. In order to write automation tests, Selenium provides the Selenium IDE, which is a plugin for Mozilla Firefox that primarily allows you to record and playback tests and export them into various languages including Java. Selenium Maven Plugin allows you to specify automation tests created for Selenium in your Maven project and integrate it with the Maven build lifecycle.
Getting ready First we need a web application project to get started. Starting the Selenium server requires it to be synced with the pre-integration test phase of your build lifecycle.
This can be done by adding the following to the project POM: org. However, to run the Selenium tests, we will need to start the web application server as well.
The Maven Jetty plugin allows us to accomplish the same: org. What's next? Of course, creating our first test! You should be seeing the header text as Hello, World. If not, fix your web application project to render the same. TestCase; org. Test; com. DefaultSelenium; com. If you look at the preceding configuration, the Selenium and Jetty plugins are configured to start in the pre-integration test phase. Thus, when the integration-test build phase is reached, Jetty and Selenium are ready and available.
Now the execution of our test case begins. In the setup , we create a Selenium client. See also Test driven development section in Chapter 2, Software Engineering Techniques 43 Software Engineering Techniques Deployment automation The Maven Deploy Plugin is used to add artifact s to a remote repository during the deploy phase of the build lifecycle.
The deploy plugin introduces two goals: ff deploy:deploy: To deploy a project and all its artifacts ff deploy:deploy-file: To deploy a single artifact file Getting ready Deployment to a repository means not only to copy the artifacts to a folder but to update metadata regarding the artifacts as well.
It requires: ff Target repository: Target repository is where the artifacts will be deployed. Artifact groupId, artifactId, version, packaging, and classifier information are required. The project POM must include a valid element, which provides a element defining the remote repository location for the artifact.
For this, you need to specify a server definition in your settings.

The Apache Maven Deploy plugin is invoked usually during the deploy phase of the build life cycle. As we just saw, a element with a element in it are required to enable this plugin. Snapshots and releases can be separated by defining a element, whereas site deployments require a element. The element is inherited allowing for registry of this information in the parent POM file to make them available to all sub-modules.
The actual deployment takes place based on the protocol defined in the repository with the commonly used protocols being FTP and SSH. There's more If the remote repository is accessible through FTP, then the project POM build elements need to include the specification of the wagon-ftp extension. Hence SSH-based deployments allow secure deployments when required.
One thing common to the recipes covered here is that they are context sensitive and cater to situations that arise in medium to large software development teams. This is a chapter for Agile teams, but can be useful for any team, regardless of the methodologies followed.
However, it is recommended that one is familiar with practices that are followed by Agile teams because for many situations these practices are ideal. A good example of this is the practice of pair programming. While it is an extremely effective practice for any team, in the context of a distributed team, pair programming becomes critical and its success can have a direct impact on the health of the team and the project. Some of these techniques are well documented and have been popularized by software engineering methodologies such as Extreme Programming.
Stay ahead with the world's most comprehensive technology and business learning platform.
The recipes here offer glimpses at how these can be implemented using Maven in situations, where one is dealing with Agile, distributed and cross functional teams. Apache Maven projects can be dependent on other "artifacts".
These artifacts can be other projects or external libraries. Apache Maven stores all packaged artifacts in a local repository. In the instances where we have dependencies that aren't available in the local repository, we see that Apache Maven automatically downloads them from the Maven Central Repository. It is possible that our projects have unique dependencies that aren't available in the Apache Maven Central Repository.
Apache Maven does let you manually add libraries into the local repository through the command line.The archetype:generate command also requires you to fill in the Apache Maven project co-ordinates including the project groupId, artifactId, package, and version.
