# Setting up Your Maven Environment

Once you have Maven installed, either as part of a Fusion Middleware package, or from the Apache website, you need to perform a few initial steps to set up your environment.

## How to Set Up Your Maven Environment

The first thing you need to do to use Maven is to set your environment variables.

To set up your environment on Unix:

1. Add Maven to your operating system's PATH:

   - Update your shell startup script, your `.profile` or `.bash_profile`, to update the path. For example, if you have installed Oracle WebLogic Server in `/u01/fmwhome` and you are using the bash shell, then add the following to the PATH environment variable:

     `export M2_HOME=/u01/fmwhome/oracle_common/modules/org.apache.maven_3.0.4`

     `export PATH=${M2_HOME}/bin:$PATH`

2. Set the JAVA_HOME environment variable to point to your JDK installation, for example, export `JAVA_HOME=u01\jdk1.7.0`

To set up your environment on Windows:

1. Edit your PATH environment variable and add the correct Maven directory path at the beginning of the PATH environment variable. For example, if you have installed your Fusion Middleware in `c:\fmwhome`, then add the following:

   `C:\fmwhome\oracle_common\modules\org.apache.maven_3.0.4\bin`

2. Set the `JAVA_HOME` environment variable to point to your JDK installation, for example, export `JAVA_HOME=C:\Oracle\Middleware\jdk1.7.0`

3. Add the M2_HOME environment variable by opening up the system properties (WinKey + Pause), selecting the Advanced tab, then the Environment Variables button. Add the M2_HOME variable in the user variables with the value `C:\<ORACLE_HOME>\oracle_ common\modules\org.apache.maven_3.0.4\bin`\. If you installed Maven from the Apache website, the value will be `C:\Program Files\Apache Software Foundation\apache-maven-3.0.5.`

4. In the same dialog, add the user variable with the value `%M2_HOME%\bin`

5. Open a new command prompt (Winkey + R then type cmd) and run `mvn --versio`n to verify that it is correctly installed.
