Step 1 – Verify Java Installation in Your Machine
First of all, open the console and execute a java command based on the operating system you are working on.
| OS | Task | Command |
|---|---|---|
| Windows | Open Command Console | c:> java -version |
| Linux | Open Command Terminal | $ java -version |
| Mac | Open Terminal | machine:< joseph$ java -version |
Let”s verify the output for all the operating systems −
| OS | Output |
|---|---|
| Windows |
java 11.0.11 2021-04-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9-LTS-194)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.11+9-LTS-194, mixed mode)
|
| Linux |
java 11.0.11 2021-04-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9-LTS-194)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.11+9-LTS-194, mixed mode)
|
| Mac |
java 11.0.11 2021-04-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9-LTS-194)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.11+9-LTS-194, mixed mode)

If you do not have Java installed on your system, then download the Java Software Development Kit (SDK) from the following link http://www.oracle.com. We are assuming Java 11.0.11 as the installed version for this tutorial.
Step 2 – Set JAVA Environment
Set the JAVA_HOME environment variable to point to the base directory location where Java is installed on your machine. For example.
| OS | Output |
|---|---|
| Windows | Set the environment variable JAVA_HOME to C:Program FilesJavajdk11.0.11 |
| Linux | export JAVA_HOME = /usr/local/java-current |
| Mac | export JAVA_HOME = /Library/Java/Home |
Append Java compiler location to the System Path.
| OS | Output |
|---|---|
| Windows | Append the string C:Program FilesJavajdk11.0.11bin at the end of the system variable, Path. |
| Linux | export PATH = $PATH:$JAVA_HOME/bin/ |
| Mac | not required |
Verify Java installation using the command java -version as explained above.
Step 3 – Download Maven Archive
Download Maven 3.8.4 from https://maven.apache.org/download.cgi.
| OS | Archive name |
|---|---|
| Windows | apache-maven-3.8.4-bin.zip |
| Linux | apache-maven-3.8.4-bin.tar.gz |
| Mac | apache-maven-3.8.4-bin.tar.gz |
Step 4 – Extract the Maven Archive
Extract the archive, to the directory you wish to install Maven 3.8.4. The subdirectory apache-maven-3.8.4 will be created from the archive.
| OS | Location (can be different based on your installation) |
|---|---|
| Windows | C:Program FilesApache Software Foundationapache-maven-3.8.4 |
| Linux | /usr/local/apache-maven |
| Mac | /usr/local/apache-maven |
Step 5 – Set Maven Environment Variables
Add M2_HOME, M2, MAVEN_OPTS to environment variables.
| OS | Output |
|---|---|
| Windows |
Set the environment variables using system properties.
M2_HOME=C:Program FilesApache Software Foundationapache-maven-3.8.4 M2=%M2_HOME%bin MAVEN_OPTS=-Xms256m -Xmx512m
|
| Linux |
Open command terminal and set environment variables.
export M2_HOME=/usr/local/apache-maven/apache-maven-3.8.4 export M2=$M2_HOME/bin
export MAVEN_OPTS=-Xms256m -Xmx512m
|
| Mac |
Open command terminal and set environment variables.
export M2_HOME=/usr/local/apache-maven/apache-maven-3.8.4
export M2=$M2_HOME/bin
export MAVEN_OPTS=-Xms256m -Xmx512m
|
Step 6 – Add Maven bin Directory Location to System Path
Now append M2 variable to System Path.
| OS | Output |
|---|---|
| Windows | Append the string ;%M2% to the end of the system variable, Path. |
| Linux | export PATH=$M2:$PATH |
| Mac | export PATH=$M2:$PATH |
Step 7 – Verify Maven Installation
Now open console and execute the following mvn command.
| OS | Task | Command |
|---|---|---|
| Windows | Open Command Console | c:> mvn –version |
| Linux | Open Command Terminal | $ mvn –version |
| Mac | Open Terminal | machine:~ joseph$ mvn –version |
Finally, verify the output of the above commands, which should be as follows −
| OS | Output |
|---|---|
| Windows |
