How to Install Maven in Eclipse Oxygen

For use with a project, the Maven for Eclipse is used to create Eclipse IDE files like *.classpath, *.project, *.wtpmodules, and the .settings folder. In this article, we will discuss how to install Maven in Eclipse Oxygen. It is recommended to install M2E (Maven to Eclipse) which offers several fantastic features, M2Eclipse offers tight integration of Apache Maven into the Eclipse IDE. There are two ways used to install the maven plugin in eclipse IDE one is through the complicated command prompt and the other one is easy which we will discuss in detail.

What is the Maven  #

Maven comprises a core engine that manages the build process and basic project processing functions, as well as a variety of plugins that carry out the actual build activities. Maven is only a base framework for several Maven Plugins. To put it another way, plugins are where most of the actual work is done. They are used to produce jar files, war files, compile code, unit test code, build project documentation, and a plethora of other things. Almost any task you can imagine carrying out on a project has been implemented as a Maven plugin.

The main component of Maven that enables the reuse of common build logic across numerous projects is plugins. They accomplish this by carrying out an "activity" in the context of a project's description, or the Project Object Model, such as generating a WAR file or compiling unit tests (POM). A description of each plugin objective exposes a collection of special options that can be used to alter how the plugin behaves.

The Clean Plugin in Maven is one of the most basic plugins. The target directory of a Maven project is removed by the Maven Clean plugin (maven-clean-plugin). The target directory is deleted when you run "mvn clean", which causes Maven to carry out the "clean" goal as specified in the Clean plug-in. A parameter that can be used to alter the behavior of the Clean plugin is defined.

Benefits of the maven plugin in eclipse IDE  #

Eclipse has a fantastic plugin called m2eclipse that easily connects Maven and Eclipse. The following list of M2E's key advantages includes:

  • Maven objectives can be executed from Eclipse.
  • With the help of Eclipse's built-in console, you can see the results of Maven commands.
  • With an IDE, you can update maven dependencies.
  • From Eclipse, you may launch Maven builds.
  • It manages dependencies for the Eclipse build path depending on the Maven pom.xml.
  • It resolves Maven dependencies without adding them to the local Maven repository in the Eclipse workspace (requires dependency project to be in the same workspace).
  • It automatically downloads the necessary sources and dependencies from the distant Maven repositories.
  • It offers wizards for generating new pom.xml files, new Maven projects, and for turning on Maven support for already-existing projects.
  • Remote Maven repositories offer a rapid search for dependencies.

The Maven build system is already supported by the majority of Eclipse IDE downloads. Use Help About to see whether you can see the Maven logo (with the M2E sign) to be sure. The instructions in the accompanying description can be used to install Maven support if it is not already set up.

Installation through eclipse  #

  • Select "Install New Software" from the Help menu at the top of Eclipse.
  • On the newly created window, click the Add button.
  • Type "Maven" in the Name field and"http://download.eclipse.org/technology/m2e/releases/" in the Location box.

Note: The Maven for Eclipse download can be found at the URL.

  • In the pop-up window, there will be a checkbox. Select the Maven integration check box and click the next button.
  • Please give the window some time to finish processing before attempting to use it. No more than two or three minutes will pass.
  • Click the Next button while keeping the default settings in place.
  • By selecting the Finish button, you agree to the "Terms and Conditions" and continue.
  • As the installation is being completed, wait.
  • You will be prompted to restart Eclipse after the installation is complete. Please select Yes so that the changes will be properly reflected.
  • This concludes the Maven in Eclipse installation. The next chapter is all about the alternative method of installing Maven, which is using the command line. As a result, your installation was done correctly.

Installation through Windows (Command Prompt)  #

If Java isn't already installed on your system, do so now.

  • Please open the command prompt by selecting Run from the menu and typing "cmd" to check the Java version that is installed on your computer.
  • Now enter "Java -version" once you have typed it.

Set the Java Environment Variable once Java has been installed. Open System Settings to modify the Java environment variable.

  • By right-clicking on any blank area in My Computer, navigate to My Computer and choose Properties.
  • Then select "Change settings".
  • When a pop-up box appears, select the 'Advanced' tab, then select 'Environment Variables.
  • Select the New option next to "System Variables".
  • Write "JAVA HOME" in the Variable name box, enter the JDK path "C:\Program FilesJavajdk1.8.0 20", and then click OK.
  • Under "System Variables," an entry for a freshly created Java variable will be shown.
  • The next step is to download Maven, which may be done by visiting https://maven.apache.org/download.cgi, which is the official source.
  • Set up the Maven Environment Variable in the same manner as the Java Environment Variable by extracting it to a specific location.

“MAVEN HOME” should be entered in the Variable name box, followed by the Maven path 8C:apache-maven-3.2.3*, and clicking OK.

  • By right-clicking on any blank area in My Computer, navigate to My Computer and choose Properties.
  • Then select "Change Settings".
  • When a pop-up box appears, select the 'Advanced' tab, then select Environment Variables.
  • Under "User Variables for UserName," where UserName is your machine name, click the Edit button.
  • Enter "PATH" in the Variable name box, followed by the Maven path "C:\apache-maven-3.2.3bin", and then click OK.

The installation of Maven is finished. Let's check it out now using the Windows command prompt. Enter "cmd" in the application location search box under Run. A fresh command window will appear. At the command prompt, enter mvn -version.

The Conclusion  #

In this article, I have written the details of both methods on how to install maven in eclipse oxygen. The easy way is to use eclipse IDE to install maven, the command prompt is the complicated way to install maven in eclipse.
