In this quick tutorial, we are going to highlight how to install Maven on windows 10.
In short, Maven is a build automation and dependency management tool for Java based applications. To build a project, Maven uses its project object model (POM) and a set of plugins.
For this tutorial, I will be using:
- JDK 8
- Maven 3.8.1
- Windows 10
Note: We have also written a nice article on how to install maven on mac. Feel free to check it.
Install JDK and Set up JAVA_HOME
The installation process of Apache Maven is quite simple, we just need to extract the Maven’s zip file and set up maven environment variables.
However, Maven requires JDK to perform some important operations such as code compilation.
So, before installing Maven on Windows 10, we need to make sure that Java JDK is installed and the JAVA_HOME environment variable is configured on our machine.
Please refer to how to install on Windows 10 for more details. Another important thing to keep in mind is that:
- Apache Maven 3.3.1+ requires JDK 1.7 or above
- Apache Maven 3.2.1->3.2.5 requires JDK 1.6
- Apache Maven 2.2 to 3.1.1 requires JDK 1.5
- Apache Maven 2.0 to 2.1 requires Java 1.4
We can type the following commands to check which JDK version is installed on our machine:
C:UsersAsus>echo %JAVA_HOME%
C:Program FilesJavajdk1.8.0_261
C:UsersAsus>java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)
C:UsersAsus>
As we can see, the installed version of JDK is 1.8.0_261.
Download Apache Maven for Windows
We can download Maven directly from the official website: https://maven.apache.org/download.cgi. Make sure to download the latest stable release which now 3.8.1
Install Apache Maven on Windows 10
Now, let’s download apache-maven-3.8.1-bin.zip and unzip it to a specific folder of our choice, for example: C:UsersAsussoftapache-maven-3.8.1
That’s all, NO installation is required to work with Mvn. Cool, right?
Add MAVEN_HOME Environment Variable
The next step is to configure the MAVEN_HOME variable on Windows 10.
MAVEN_HOME should point to the folder where we extracted Maven which is C:UsersAsussoftapache-maven-3.8.1 in our case. Follow these steps to add the MAVEN_HOME environment variable:
1- Type “edit” in the Window search box, then click on the “Edit the system environment variables”
2- Next, select the “Environment Variables…” button
3- Click on the “New…” button and put MAVEN_HOME as variable name and C:UsersAsussoftapache-maven-3.8.1 as variable value
another way to set up MAVEN_HOME is to use command lines. To do so, open a new command prompt as administrator and type the following command:
C:Windowssystem32>setx /M MAVEN_HOME "C:UsersAsussoftapache-maven-3.8.1"
SUCCESS: Specified value was saved.
Add %MAVEN_HOME%bin to PATH
Now let’s add the last missing piece of the puzzle. This step is very important to run the Mvn command everywhere directly from the command prompt.
To do so conveniently, we need to edit the PATH variable by appending the Maven bin folder %MAVEN_HOME%bin.
Please bear in mind that we can accomplish the same thing using this command line:
C:Windowssystem32>setx /M PATH "%MAVEN_HOME%bin;%PATH%"
Verify Mvn Installation
Now that we put all the pieces together, let’s test if Apache Maven is successfully installed on Windows 10.
To verify the installation, we run:
C:UsersAsus>mvn --version
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: C:UsersAsussoftapache-maven-3.8.1bin..
Java version: 1.8.0_261, vendor: Oracle Corporation, runtime: C:Program FilesJavajdk1.8.0_261jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
C:UsersAsus>echo %MAVEN_HOME%
C:UsersAsussoftapache-maven-3.8.1
C:UsersAsus>
As shown above, the command indeed displays the Maven version, Maven bin folder, Java version, and operating system information.
Common Issues
1) mvn is not recognized as an internal or external command
C:UsersAsus>mvn --version
'mvn' is not recognized as an internal or external command,
operable program or batch file.
This means that the installation is not done properly, make sure %MAVEN_HOME%bin is prepended to the PATH variable the right way.
2) JAVA_HOME environment variable is not defined correctly
C:UsersAsus>mvn --version
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
This simply means that JDK is not installed and the JAVA_HOME variable is not properly configured.
3) Error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher
In this case, you need to download the binary zip archive file, instead of the source zip archive.
