    If you got something similar to the above, you can skip this section and go to the [*Configure Maven* | #Configure Maven] section.

  3. Unzip/untar the binaries to a new folder (e.g. c:\maven\2.2.1).
  4. Add the path to the Maven bin directory to the system PATH environment variable.  For example: add c:\maven\2.2.1\bin to the PATH environment variable.
  5. Verify the Maven installation by opening a CMD window and typying the command line: mvn --version.  If everything is correct, something similar to the following should be displayed:

# [Download the serverTrustStore.jks|Install Maven^serverTrustStore.jks] and save it to a new folder (e.g. c:\keystores).
# To download Maven artifacts from the remote MIT maven repository (https://maven.mit.edu), an SSL connection is required.  For Maven to acquire an SSL connection, you must create a system environment variable *MAVEN_OPTS* and set it as below:
\\
\\
* *For Mac users:*  You must set the environmental variable *_JAVA_OPTIONS* as shown below.
{code}
_JAVA_OPTIONS=-Djavax.net.ssl.trustStore=/path/to/serverTrustStore.jks -Djavax.net.ssl.trustStorePassword="XXXXXXXX" -Xmx512m -Xms512m -XX:MaxPermSize=512m
{code}
* *For Windows users:*  You must set the environmental variable *MAVEN_OPTS* as shown below.
{code}
MAVEN_OPTS=-Djavax.net.ssl.trustStore=/path/to/serverTrustStore.jks -Djavax.net.ssl.trustStorePassword="XXXXXXXX" -Xmx512m -Xms512m -XX:MaxPermSize=512m
{code}
\\
In the above, replace the */path/to* with the actual path to the serverTrustStore.jks and replace *XXXXXXXX* with the actual serverTrustStore.jks password.  If you don't know the serverTrustStore.jks password, your team leader can get it for you.
\\
\\
*For MAC users*:  You can now [download a nice plugin | Install the Oracle OC4J 10.1.3.5 standalone server^RCEnvironment-1.4.X.dmg] that helps you manage your system environmental variables.  The plugin, *RCEnvironment*, is a preference pane for MacOS X 10.1 or higher that allows editing of your ~/.MacOSX/environment.plist file.
*For Window users*:  Go to *Start > Control Panel > System > Advanced system settings > Environment Variables...* and under *System variables*, click *New* and enter the *MAVEN_OPTS* shown above.
