How to setup/install Maven Environment ?
- In computer program and software product development, the developmentenvironment is the set of processes and programming tools used to create the program or software product. The term may sometimes also imply the physicalenvironment.
- Maven is Java based tool, so the very first requirement is to have JDK installed on your machine.
System Requirement
| JDK | 1.5 or above. |
|---|---|
| Memory | no minimum requirement. |
| Disk Space | no minimum requirement. |
| Operating System | no minimum requirement. |
Step 1 - verify Java installation on your machine
- Now open console and execute the following java command.
| 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 version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13) Java HotSpot(TM) Client VM (build 24.75-b04, mixed mode, sharing) |
| Linux | java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13) Java HotSpot(TM) Client VM (build 24.75-b04, mixed mode, sharing) |
| Mac | java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13) Java HotSpot(TM)64-Bit Server VM (build 24.75-b04, mixed mode, sharing) |
- Install the java Software Development Kit (SDK) .
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.
| OS | Output |
|---|---|
| Windows | Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.7.0_75 |
| Linux | export JAVA_HOME=/usr/local/java-current |
| Mac | export JAVA_HOME=/Library/Java/Home |
- Append Java compiler location to System Path.
| OS | Output |
|---|---|
| Windows | Append the string ;C:\Program Files\Java\jdk1.7.0_75\bin to the end of the system variable, Path. |
| Linux | export PATH=$PATH:$JAVA_HOME/bin/ |
| Mac | not required |
- Verify Java Installation using java -version command explained above.
Step 3: Download Maven archive
- Download Maven 3.3.3
| OS | Archive name |
|---|---|
| Windows | apache-maven-3.3.3-bin.zip |
| Linux | apache-maven-3.3.3-bin.tar.gz |
| Mac | apache-maven-3.3.3-bin.tar.gz |
Step 4: Extract the Maven archive
- Extract the archive, to the directory you wish to install Maven 3.3.3. The subdirectory apache-maven-3.3.3 will be created from the archive.
| OS | Location (can be different based on your installation) |
|---|---|
| Windows | C:\Program Files\Apache Software Foundation\apache-maven-3.3.3 |
| 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 Files\Apache Software Foundation\apache-maven-3.3.3 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-3.3.3 export M2=$M2_HOME/bin export MAVEN_OPTS=-Xms256m -Xmx512m |
| Mac | Open command terminal and set environment variables. export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.3 export M2=$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, 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 something as follows:
| OS | Output |
