Click on the New button again and type %MAVEN_HOME%\bin. Click OK.
Click OK to close all the windows.
Verifying Maven
To verify that Maven is installed and configured correctly, open a new command prompt and type mvn -v. You should see something like this:
C:\Users\user>mvn -v Apache Maven 3.8.1 (05c21c65bdfed0feca6e2f2dfcda18f0f61312b0) Maven home: C:\apache-maven-3.8.1 Java version: 1.8.0_301, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk1.8.0_301\jre Default locale: en_US, platform encoding: Cp1252 OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
If you see something similar, congratulations! You have successfully installed Maven on your Windows system.
Configuration
Maven has two main configuration files that you can use to customize its behavior: settings.xml and pom.xml.
Setting User Settings
The settings.xml file is located in the conf directory of your Maven installation. It contains global settings that apply to all Maven projects on your system. You can edit this file to configure things such as:
The local repository where Maven stores downloaded artifacts
The remote repositories where Maven looks for artifacts
The proxies that Maven uses to access the internet
The mirrors that Maven uses to redirect requests to other repositories
The profiles that Maven activates based on certain conditions
The servers that Maven uses to authenticate with remote repositories or deployment targets
You can also create a user-specific settings.xml file in your home directory (C:\Users\user\.m2) that overrides the global settings.xml file. This is useful if you want to have different settings for different users or environments.
Setting Project Settings
The pom.xml file is located in the root directory of your Maven project. It contains project-specific settings that define what your project is, what it does, and how it does it. You can edit this file to configure things such as:
The project information such as name, description, version, URL, etc.
The project dependencies such as libraries, frameworks, plugins, etc.
The project build such as source directories, output directories, compiler options, test options, etc.
The project distribution such as packaging type, artifact name, deployment configuration, etc.
The project reporting such as documentation generation, code analysis, test coverage, etc.
Usage
Maven provides a command-line interface that you can use to perform various tasks related to your project. The general syntax of a Maven command is:
mvn [options] [goal(s)] [phase(s)]
Maven commands are composed of options, goals, and phases. Options are flags that modify the behavior of Maven such as -D for defining properties or -X for enabling debug mode. Goals are specific tasks that Maven can execute such as compile or test. Phases are stages of the build lifecycle that consist of a sequence of goals such as validate or install. You can run multiple goals and phases in a single command by separating them with spaces.
Here are some examples of common Maven commands that you can use for your project:
Creating a Project
To create a new Maven project, you can use the mvn archetype:generate command. This command will prompt you to choose an archetype, which is a template for your project. You can choose from a list of predefined archetypes or specify your own. You will also be asked to enter some information about your project such as group ID, artifact ID, version, package, etc.
For example, to create a simple Java project, you can run this command:
mvn archetype:generate -DgroupId=com.example -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
This command will generate a project with the following structure:
my-app -- pom.xml `-- src -- main `-- java `-- com `-- example `-- App.java `-- test `-- java `-- com `-- example `-- AppTest.java
Building a Project
To build your Maven project, you can use the mvn clean, mvn compile, mvn test, and mvn package commands. These commands correspond to the phases of the default build lifecycle of Maven.
The mvn clean command will delete the target directory that contains the output of the previous build. This is useful to ensure a clean state before building your project.
The mvn compile command will compile the source code of your project and place the class files in the target/classes directory.
The mvn test command will run the unit tests of your project and place the test results in the target/surefire-reports directory.
The mvn package command will package the compiled code and resources of your project into a distributable format such as a JAR, WAR, or EAR file. The packaged file will be placed in the target directory.
Running a Project
To run your Maven project, you can use the mvn exec:java command. This command will execute the main class of your project using the Java runtime. You can specify the main class using the exec.mainClass property or by configuring it in the pom.xml file.
For example, to run the App class of the simple Java project, you can run this command:
mvn exec:java -Dexec.mainClass=com.example.App
This command will print "Hello World!" to the console.
Best Practices
Maven is a powerful and flexible tool that can help you manage your Java projects more efficiently and effectively. However, to get the most out of Maven, you should follow some best practices that can improve your productivity and quality of your projects. Here are some of them:
Following Conventions
Maven follows some conventions for organizing and naming your projects, directories, files, etc. These conventions make it easier for Maven to understand and process your projects without requiring much configuration. They also make it easier for other developers to understand and work with your projects.
You should follow these conventions as much as possible unless you have a good reason not to. Some of these conventions are:
The group ID of your project should be a reverse domain name that represents your organization or group. For example, com.example.
The artifact ID of your project should be a short and descriptive name that represents your project. For example, my-app.
The version of your project should follow the semantic versioning scheme that consists of three numbers: major, minor, and patch. For example, 1.0.0.
The packaging type of your project should match the format of the artifact that you want to distribute. For example, jar, war, ear, etc.
The source code of your project should be placed in the src/main/java directory.
The resources of your project such as properties files, images, etc. should be placed in the src/main/resources directory.
The unit tests of your project should be placed in the src/test/java directory.The test resources of your project such as test data, configuration files, etc. should be placed in the src/test/resources directory.
The output of your project such as class files, test results, packaged artifacts, etc. should be placed in the target directory.
Managing Dependencies
Maven has a powerful feature that allows you to manage the dependencies of your project such as libraries, frameworks, plugins, etc. You can declare the dependencies of your project in the pom.xml file using the element. You can specify the group ID, artifact ID, and version of the dependency, as well as other attributes such as scope, type, classifier, etc.
Maven will automatically download the dependencies of your project from the remote repositories that you have configured in the settings.xml file or in the pom.xml file using the element. Maven will also resolve the transitive dependencies of your project, which are the dependencies of your dependencies. This way, you don't have to worry about managing multiple versions of the same dependency or downloading them manually.
However, you should also be careful when managing dependencies with Maven. You should follow some best practices such as:
Use the latest stable version of the dependency unless you have a specific reason to use an older or newer version.
Use the same version of the dependency across all your projects to avoid compatibility issues.
Use the appropriate scope for your dependency such as compile, test, provided, runtime, etc. to indicate when and where the dependency is needed.
Exclude any unnecessary or conflicting transitive dependencies using the element.
Check for any dependency conflicts or vulnerabilities using Maven plugins such as maven-enforcer-plugin or maven-dependency-plugin.
Using a Repository Manager
A repository manager is a tool that acts as a proxy, cache, and manager for Maven repositories. It can help you improve the performance and security of your Maven projects by providing features such as:
Caching remote artifacts locally to reduce network traffic and latency.
Mirroring remote repositories to provide faster and more reliable access.
Hosting local repositories to store and share your own artifacts.
Grouping repositories to provide a single access point for multiple repositories.
Securing repositories to control access and permissions.
Managing repositories to monitor and optimize their usage and health.
You should use a repository manager for your Maven projects if you want to benefit from these features. Some popular repository managers for Maven are Nexus and Artifactory. You can install and configure them on your own server or use their cloud-based services. You can also integrate them with your IDE and other tools that you use for your development workflow.
Common Errors and Solutions
Maven is a complex tool that can sometimes produce errors or unexpected results. These errors can be caused by various factors such as incorrect configuration, network issues, dependency conflicts, etc. Here are some common errors that you may encounter when working with Maven and how to solve them:
Compiler Version Problems
If you see an error message like this:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project my-app: Fatal error compiling: invalid target release: 11 -> [Help 1]
It means that Maven is trying to compile your project using a Java version that is different from the one that you have installed or specified. This can happen if you have multiple versions of Java on your system or if you have not set the JAVA_HOME variable correctly.
To fix this problem, you can do one of the following:
Set the JAVA_HOME variable to point to the correct JDK installation.
Specify the source and target properties in the pom.xml file to match the Java version that you want to use. For example:
11
11
Specify the Java compiler settings in your IDE to match the Java version that you want to use.
Project Won't Start or Import
If you see an error message like this:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test (default-test) on project my-app: Execution default-test of goal org.apache.maven.plugins:maven-surefire -plugin:2.12.4:test failed: The forked VM terminated without properly saying goodbye. VM crash or System.exit called? -> [Help 1]
It means that Maven is unable to start or import your project due to insufficient memory or other system resources. This can happen if you have a large or complex project that requires more memory than the default settings of Maven allow.
To fix this problem, you can do one of the following:
Increase the heap size for the Maven importer in your IDE. For example, in Eclipse, you can go to Window > Preferences > Maven > Importing and set the VM options for importer to something like -Xmx1024m.
Increase the heap size for the Maven command line by setting the MAVEN_OPTS environment variable. For example, you can run this command before running Maven:
set MAVEN_OPTS=-Xmx1024m
Check your network settings and make sure that you can access the remote repositories that Maven needs to download dependencies from.
Update your Maven repositories by running mvn clean install -U to force Maven to check for the latest versions of dependencies.

FAQs
What is the difference between Maven and Gradle?
Maven and Gradle are both popular tools for managing Java projects, but they have some differences in terms of features, syntax, and performance. Some of the main differences are:
Maven uses XML to define the project configuration, while Gradle uses a Groovy-based DSL (Domain Specific Language) that is more concise and expressive.
Maven follows a fixed and linear build lifecycle that consists of predefined phases and goals, while Gradle follows a flexible and dynamic build model that allows custom tasks and dependencies.
Maven relies on external plugins to provide additional functionality, while Gradle has built-in support for many features such as dependency management, testing, code quality, etc.
Maven tends to be slower and more memory-intensive than Gradle, especially for large or complex projects.
How do I update Maven to the latest version?
To update Maven to the latest version, you can follow these steps:
Download the latest binary zip archive of Maven from the website.
Extract the zip file to a directory of your choice.
Delete or rename the old Maven directory that you have installed previously.
Set the MAVEN_HOME environment variable to point to the new Maven directory that you have extracted.
Verify that Maven is updated by running mvn -v.
How do I add a dependency to my project?
To add a dependency to your project, you need to edit the pom.xml file and add a element inside the element. You need to specify the group ID, artifact ID, and version of the dependency that you want to use. For example, to add JUnit as a test dependency, you can add this code:
...
junit
junit
4.13.2
test
...
You can find the information about the dependencies that you want to use from sources such as the website, which contains a searchable index of Maven artifacts.
After adding the dependency to your pom.xml file, you need to run mvn clean install to download the dependency and update your project.
How do I create a JAR file for my project?
To create a JAR file for your project, you can use the mvn package command. This command will compile your source code, run your tests, and package your project into a JAR file that will be placed in the target directory.
However, by default, the JAR file that Maven creates does not include the dependencies of your project. This means that you will need to provide the dependencies separately when you run or distribute your JAR file. To include the dependencies in your JAR file, you can use the plugin. This plugin will create an executable JAR file that contains all the dependencies of your project.
To use this plugin, you need to add it to your pom.xml file inside the element. For example, you can add this code:
...
org.apache.maven.plugins
maven-shade-plugin
3.2.4
package
shade
...
This code will tell Maven to use the shade plugin during the package phase and create a shaded JAR file that contains all the dependencies of your project. You can also customize the plugin configuration to change the name, location, or content of the JAR file.
How do I generate documentation for my project?
To generate documentation for your project, you can use the mvn site command. This command will generate a website that contains information about your project such as description, dependencies, reports, etc. The website will be placed in the target/site directory.
To customize the content and appearance of the website, you can edit the site.xml file in the src/site directory of your project. You can also add additional files such as images, CSS, etc. to the src/site/resources directory.
You can also use various Maven plugins to generate different types of reports for your project such as JavaDoc, test coverage, code analysis, etc. You can add these plugins to your pom.xml file inside the element. For example, you can add this code:
...
...
org.apache.maven.plugins
maven-javadoc-plugin
3.3.0
...
...
This code will tell Maven to use the javadoc plugin to generate JavaDoc for your project and include it in the website. 44f88ac181
